# COMPLEX Docs
|
||||
|
||||
Цей проєкт має на меті надати зручний доступ до документації програми емуляції цифрової ЕОМ, що має назву КОМПЛЕКС (також відома як МікроЕОМ та COMPLEX), а також перекласти її зрозумілою українською мовою з англо-російської.
|
||||
|
||||
## Структура проєкту
|
||||
|
||||
Файли документації та її перекладу зберігаються у відповідних теках `docs/*`.
|
||||
|
||||
Повний текст оригінальної документації можна знайти у файлі `docs/original/total.txt`. Він розбитий на частини, що стосуються програми загалом (файли `docs/original/complex-*.txt`) та компілятора мікроасемблера COMANDOR (файли `docs/original/comandor-*.txt`).
|
||||
|
||||
Тексти перекладів знаходяться у відповідних каталогах `docs/*`, що містять файли перекладів `complex-*.txt` та `comandor-*.txt`. Зверніть увагу, що в каталогах перекладів відсутні файли `total.txt`: вони формуватимуться у відповідному каталозі `build/` під час побудови документації.
|
||||
|
||||
Інструменти (зокрема, для побудови документації) знаходяться у каталозі `utils/`.
|
||||
|
||||
## Побудова документації
|
||||
|

Foreword.
|

══════════
|
||||
|
||||
Mnemonic two-pass assembler "COMANDOR" is intended to
|
||||
relief of the laborious labour of the programmer on writing the micro-
|
||||
instructions of the microprocessor system "COMPLEX", debug and
|
||||
performing the programs on software emulator, and quick contributing
|
||||
the changes to source text.
|
||||
The result of the functioning the assembler on translations of the
|
||||
source text file is a file with extension '.pmk', and its queue source
|
||||
for programm emulator of the microprocessor complex.

|
||||
1. Source file.
|
||||
═══════════════
|
||||
|
||||
As source file for translation is a usual text file, for which
|
||||
equitable following rates of the writing:
|
||||
|
||||
1) all unadulterated mnemonics must be written together,assembler
|
||||
does not make differences between title and small letter of the
|
||||
alphabet, so mnemonics
|
||||
|
||||
'ADD' 'AdD' 'ADd' 'Add' 'aDD'
|
||||
|
||||
are identical and assembler do not differ them;
|
||||
|
||||
2) between separate mnemonics, digital constant, mark, correspo-
|
||||
ndence and comments can be pleaced many insignificant symbol
|
||||
and controlling sign, such as gap, tabulation, return the
|
||||
carriage, linefeed etc.,there are no restrictions on accomodation
|
||||
of the commands in text is not imposed; this allows programmer
|
||||
an enough liberally to pertain to text of programm with standpoint
|
||||
of its exterior;
|
||||
|
||||
3) follows to point to the fact, that assembler supports the
|
||||
higher part of the table symbol ASCII, in which is
|
||||
enclosed national alphabet, but all standard mnemonics,
|
||||
provided in a ⁿ1 table-addon of reserved mnemonics,
|
||||
was translated for latin alphabet, and so necessary neatly
|
||||
to pertain a wadding of mnemonics, that have in its
|
||||
composition symbols, which are equally writed, but having
|
||||
differ coding. However, given rule does not mean that
|
||||
programmer must avoid the national alphabet, except
|
||||
for writing explaining commentaries that is complitly seen
|
||||
in such programming languages, which were are oriented
|
||||
only on english user. By help of the labels structures
|
||||
and correspondence the user can in any place of its
|
||||
source file assign comprehensible for him indication and
|
||||
use it with standard mnemonics of the language.
|
||||
So such, for instance, command, as
|
||||
|
||||
Sum up operand1, operand2;
|
||||
|
||||
will not contain mistake and it is will be translated correctly
|
||||
under that condition that all provided in example of mnemonics
|
||||
will beforehand described.
|
||||
|
||||
4) the main file must be ended of the microprocessor command, that is
|
||||
concluded in quotation marks.
|
||||
|
||||
Strictly keeping rules of commands writing, the neatness in set
|
||||
of the text of the program will guarantee the quick translation and
|
||||
debug - the practice is witnesses that majority error appears firstly
|
||||
of all because stile of writing is careless and the inexact knowledge
|
||||
of the development object.

2. Numeric constants.
|
||||
═════════════════════
|
||||
|
||||
The numeric constants are used at assigning the numeric operand,
|
||||
the addresses transition and load constants. The sign of the constant
|
||||
is a value at the beginning of initially mnemonics. "COMANDOR"
|
||||
distinguishes four main forms of the value assign:
|
||||
|
||||
1) decimal form:
|
||||
10
|
||||
0
|
||||
65535
|
||||
|
||||
2) hexadecimal form:
|
||||
0Ah
|
||||
15H
|
||||
0FFFFh
|
||||
|
||||
3) octonary form:
|
||||
7o
|
||||
177777o
|
||||
|
||||
4) binary form:
|
||||
011%
|
||||
1111111111111111%
|
||||
|
||||
All constants cannot exceed size of the machine word.
|
||||
|
||||
Except direct assign of the constant in command You may refer to the
|
||||
current Pointer of the Command CP. The Assembler transforms it in the
|
||||
current numerical value of the Command Pointer .

3. Marks.
|
||||
═════════
|
||||
|
||||
The marks is serves for change often used constants on symbolic
|
||||
equivalent for increasing read ability of the source text.
|
||||
|
||||
Main rules for writing the marks:
|
||||
|
||||
1) symbols, which can not be included in marks:
|
||||
# $ ( ) * + , - . / [ \ ] { | }
|
||||
|
||||
2) mark can not begin from numerals values;
|
||||
|
||||
3) the sign of mark ending is any sign of punctuation,
|
||||
gap, sign of tabulations, the end of line, as well as
|
||||
any one of symbol, enumerated in rule 1;
|
||||
|
||||
4) the mark is not comply with reserved mnemonics (see
|
||||
exhibit 1 - a table of reserved mnemonics);
|
||||
|
||||
5) the length of the mark can be assign arbitrarily, but
|
||||
assembler will recognize only first ten symbols; so
|
||||
when use the marks more than ten symbols then in
|
||||
translations can appear some mistakes;
|
||||
|
||||
Examples of the marks writing: - Loop
|
||||
- First_go
|
||||
- Mark_1
|
||||
- To_long_mark_is_incorrect

4. Commentary.
|
||||
══════════════
|
||||
|
||||
The commentary are used for explanation of one or another
|
||||
command functioning, or the whole program as a general, as
|
||||
well as for "commenting" some checking command.
|
||||
Begin sign of commentary is a special symbol
|
||||
|
||||
'\'.
|
||||
|
||||
The assembler ignores all meeting symbols before the next
|
||||
symbol '\' or to the next line. For instance:
|
||||
|
||||
\ short example of the program \
|
||||
{ add RB,X,Z; } \ load X in R10
|
||||
{ add R11,Y,Z; } \ load Y in R11
|
||||
{ add RQ,R10,Z; \ rewrite X in RQ
|
||||
cjp l1,compute; } \ if number is positive that moves to
|
||||
\ calculation
|
||||
{ sub RQ,Z,RQ; } \ otherwise bring X to positive
|
||||
{ sub R11,Z,R11; } \ convert Y for correct sign

5. Structure of the microinstruction task.
|
||||
══════════════════════════════════════════
|
||||
|
||||
The memory of microinstructions in microprocessor complex contains
|
||||
the separate microinstructions, each of which is divided on many field.
|
||||
The command of the assembler is modifies some parts of microinstruction
|
||||
field. Whole microinstruction is assigned by operator for microinstruction
|
||||
assign, which is described by assistans of two figured bracket
|
||||
{}
|
||||
Thereby collection of the assembler commands is limited inwardly
|
||||
'{}' and presents one microinstruction of the microprocessor complex.
|
||||
Inwardly bracket can be kept any amount of the commands of
|
||||
assembler, or no one. So even at assigning of empty microinstruction
|
||||
you determine actions, that produced in emulator of the microprocessor.
|
||||
Usually - it's "empty" actions that corresponding to command NOP if
|
||||
it existed.
|
||||
Main rules of the commands writing on assembler language "COMANDOR" is
|
||||
described below:
|
||||
|
||||
1) all commands of the assembler must be fited inwardly in operator of
|
||||
the microinstruction assign '{}';
|
||||
|
||||
2) command always begins with name of the command, which is reserved
|
||||
mnemonics;
|
||||
|
||||
3) operands divide between itself by operator of the division operands
|
||||
',';
|
||||
|
||||
4) command must be ended by operator of the command end ';';

6. Arithmetic-logical commands.
|
||||
═══════════════════════════════
|
||||
|
||||
The arithmetic-logical commands serves for performing some microinstruction
|
||||
as adding, subtractions, bitwise logical operation, operation of the shifts,
|
||||
loading, inversion of separate register in Arithmetic-Logical Unit (ALU),
|
||||
that is built on four microcircuits BC1 and one m/c BP2.
|
||||
In a whole there is 7 commands, formats of which will are considered in
|
||||
given section:
|
||||
|
||||
1)ADD - arithmetical adding;
|
||||
2)SUB - arithmetical subtraction;
|
||||
3)OR - logical adding;
|
||||
4)AND - logical multiplying;
|
||||
5)XOR - logical subtraction (excluding "OR");
|
||||
6)NAND - logical multiplying in which first operand is taking
|
||||
with inversion;
|
||||
7)NXOR - logical subtraction in which result is inverted;
|
||||
|
||||
Next will be considered:
|
||||
|
||||
6.1. Assign of register shifts.
|
||||
6.2. Assign of the result receiver.
|
||||
6.3. Assign of operand, on which is executed some operation.
|
||||
6.4. Assign of the input carrying.
|
||||
|
||||
6.1. Receiver of the result.
|
||||
────────────────────────────
|
||||
|
||||
As receiver of the result can emerge the following operands:
|
||||
|
||||
1) RQ - work registers of ALB;
|
||||
|
||||
2) R0..R15 - one of the register of the general-purpose (RGP);
|
||||
|
||||
3) RB - RGP, number of which is determined in RB;
|
||||
|
||||
4) NIL - the empty receiver (the result is not saved, but can protrude on
|
||||
BD, as well as can be used flags, which are installed when the
|
||||
operations is perform).
|
||||
|
||||
The assigning of the RB implies use of RGP, the number of which is kept
|
||||
in stood register RB.
|
||||
|
||||
|
||||
6.2. Operands, on which operation is assigned.
|
||||
────────────────────────────────────────────────
|
||||
|
||||
Any one of described above commands allows to execute the
|
||||
actions on two operands and place the result in to operations
|
||||
register, in general event not coinsiding with operand, on which
|
||||
operation was executed. For example,
|
||||
|
||||
ADD RQ,R1,R2;
|
||||
|
||||
But often receiver of the result is simultaneously and one of the
|
||||
worker operand. Then possible lower writing of this operand twice,
|
||||
and assembler by itself will be undertake the task hipping an
|
||||
operand commands. For example:
|
||||
|
||||
SUB RQ,1;
|
||||
|
||||
Here is possible operands, which possible indicate when command assign:
|
||||
|
||||
1) Z - "internal" zero, specially realization in
|
||||
BC1 chip is to protect data bus from frequent
|
||||
trivial information;
|
||||
|
||||
2) RQ - work register of ALB;
|
||||
|
||||
3) R0..R15 - one of the general-purpose register;
|
||||
|
||||
4) RA,RB - GPR, number of which is determined in RA or RB;
|
||||
|
||||
5) numeric constant;
|
||||
|
||||
6) BUS_D - writing of such operand speaks of that, that
|
||||
operand will be scanned from data bus.
|
||||
|
||||
|
||||
6.3. Assign of shift register.
|
||||
──────────────────────────────
|
||||
|
||||
6.3.1. Structured scheme of the shift performing on ALB.
|
||||
6.3.2. Standard types of shifts.
|
||||
6.3.3. General types of shifts.
|
||||
|
||||
The arithmetic-logical block, on which is built ALU of microprocessor
|
||||
complex has as one of their own function possibility of simultaneously
|
||||
with execution one of the arithmetic-logical operation to produce the shift
|
||||
of the register-receiver. Control of shift type is realized by microinstruction,
|
||||
entering on entry MI(10-6) m/c BR2. Shift is assigned by microinstruction
|
||||
MI(8) m/c BH1. Herewith is possible to realize simultaneous shift of worke
|
||||
register RQ. For this purpose is necessary to place before operand of the
|
||||
shift the operator of the modification
|
||||
|
||||
"@"
|
||||
|
||||
which is indicates to assembler that is produced simultaneous shift of the
|
||||
register-receiver and work register RQ. For example:
|
||||
|
||||
ADD @SRA,R4,123H;
|
||||
|
||||
The assembler allows to define any one of possible types of the
|
||||
shift, or using one of the standard shift. Below brought all possible
|
||||
types of shift and operands, by means of which their are possible
|
||||
to assign.

When assign the double standard shift it is necessary to write
|
||||
accordingly SRWL SLWL SRWA SLWA.
|
||||
|
||||
For example: ADD SRA,R4,0;
|
||||
XOR SLWL,RQ,1010101010101010%;
|
||||
|
||||
|
||||
6.3.3. General types of shifts.
|
||||
─────────────────────────────────────
|
||||
They Are Assigned by type of shift (SR - a right shift, SL - a left
|
||||
shift) and type of the shift. The Type of the shift is assigned by its
|
||||
number (refer to table for BP2_MI.A-6), specified through point
|
||||
directly for type of the shift , for example:
|
||||
ADD SR.3, R0, R5, R3;
|
||||
XOR SL.18, R0, 10;
|
||||
Point to the fact, the type of right shifts (SR) is assigned by number
|
||||
from 0 to 15 and the type of left shifts (SL) by number from 16 to 31.
|
||||
|
||||
6.4. Entering carry.
|
||||
───────────────────
|
||||
Entering carry is assigned in command of the first subgroup (ADD and
|
||||
SUB).This operand is unnecessary and is by default considered equal zero.
|
||||
In the event of evident inputting of the carrying its necessary to set it
|
||||
in quality of the last operand of the command. The Inputting of the
|
||||
operand of the carrying influences on the field MI(5-0) of controller shift
|
||||
m/c BP2 of microinstructions. Here follows to take into account that this
|
||||
field is responsible also for loading of register of marks RM and RN m/c
|
||||
BP2; so be cearful in simultaneous use the commands of the arithmetical
|
||||
adding(subtractions) and commands of the loading of register of marks,
|
||||
because it can occur the accompaniment of the undesirable input carrying
|
||||
that will distort the result. The Translator of the assembler do not checks
|
||||
the compatibility of the commands and a mistake under said event will not give.
|
||||
|
||||
|
||||
|
||||
The following possible signals of the entering carry are exist:
|
||||
|
||||
1) Z - a signal of the logical zero;
|
||||
|
||||
2) RM_C - a bit C of register of the mark RM;
|
||||
|
||||
3) RN_C - a bit C of register of the mark RN.
|
||||
|
||||
It possible to assign the inversion of these signals by means of last
|
||||
operator to inversions "NOT". The Examples:
|
||||
ADD R1,RQ,R5,RM_C;
|
||||
SUB RQ,R4,not Z;
|
||||
ADD @SRA,R5,10,not RN_C;
|
||||
|
||||
The using of the operand of the carrying requires the full task of the
|
||||
command.

|

|
||||
Many commands BY4 execute the modification of the counter of the micro-
|
||||
instructions, executing hereunder the transition on new microinstruction,
|
||||
not residing directly behind executed in memories of the microinstructions.
|
||||
The Other commands can execute the modification of the register of the
|
||||
address. All address and data for loading enter on BY4 with Buses of the
|
||||
Address of the Transition (BAT). On BAT data can enter with three buffers:
|
||||
- the buffer V;
|
||||
- the buffer M;
|
||||
- the buffer P.
|
||||
As can be seen from schemes situated below, each of these buffers is
|
||||
commuted with different source of data:
|
||||
- the buffer V sends on BAT the data from ROM vectors of transition m/c BH1;
|
||||
- the buffer M commute BAT and Data Bus (look on directive LINK M);
|
||||
- the buffer P sends on BAT data from ROM of microinstructions (field D);

|
||||
If while inputting commands it is required to indicate the condition of its
|
||||
execution,then it is put after mnemonics of the command as first operand;if is
|
||||
it additionally required to indicate the direct address of the transition, or
|
||||
(for command LDCT) to assign new value of the register of the address RA, then
|
||||
numerical value (the mark) handles in command as a second operand:

7.3. Operands of inputting the conditions.
|
||||
─────────────────────────────────────────
|
||||
|
||||
The operands of the inputting of the condition are used in such commands
|
||||
as CJS, CJP, PUSH, JSRP, CJV, JRP, CRTN, CJPP, LOOP and TWB. The Signal of
|
||||
the condition is given on entry of LU block of microprogramming management
|
||||
through eight-entered multiplexor MS, two entries of which are beforehand
|
||||
predestined as Z and NZ (0 and 1), but the rest of six entries can be commuted
|
||||
by different signals (refer to inputting of switchings of the conditions with
|
||||
help of directives LINK). While inputting of the operand of the condition it
|
||||
is possible to use following predestined mnemonics:
|
||||
|
||||
1)Z, NZ - condition is defined as undoubtedly false (true);;
|
||||
|
||||
2)ZO, CO, NO, VO - signs of the zero, carrying, sign and overflows defined
|
||||
by result of the execution of operation in ALU;
|
||||
|
||||
3)RM_Z,RM_C,RM_N,RM_V - the flags Z, C, N and V keeping in register of the
|
||||
marks RM;
|
||||
|
||||
4)RN_Z,RN_C,RN_N,RN_V - similarly for RN;
|
||||
|
||||
5)NXORV - sign of the overflow for system with two digits of signs;
|
||||
|
||||
6)ZORC - condition is became true when there is a flag of zero or
|
||||
overflows in ALB after operation
|
||||
(ZORC = Z or C).
|
||||
|
||||
7)L1,L2,L3,L4,L5,L6 - a direct inputting of the number of the entering
|
||||
of the multiplexor of the conditions, from which the condition signal will
|
||||
be scanned, and the installation of the signal will not be realized.
|
||||
|
||||
Writing the operator "not" is applicable preliminary to all sign that
|
||||
influences upon field COM of microprogramming block of management BY4.
|
||||
All signals it is necessary to lock beforehand with one of the enterences
|
||||
(L1..L6) of the multiplexor by directive LINK .

8. Commands of the processing of the interruptions.
|
||||
════════════════════════════════════════════════
|
||||
|
||||
The Commands of the processing of the interruptions fill the field of
|
||||
microinstruction m/c BH1. The chip KM1804BH1 - is 8-digits microprogramming
|
||||
scheme (with ability to be increased) of the vector priority interruption,
|
||||
which produces processing by priority of inquiry for interruptions, which
|
||||
enter by eight buses from different devices.
|
||||
Commands of management m/c and types of their writing are brought Below:
|
||||
|
||||
1)RESET - a command for cleaning;
|
||||
can be without or with one operand;
|
||||
|
||||
a)command RESET without operands conducts general clearing.
|
||||
While this command is executed the zeroizing of the register of
|
||||
the condition occures and trigger of the permit of the request
|
||||
of the interruption moves into condition, which allows leaving of
|
||||
the request of the interruption, a.w. system of the interruption
|
||||
will react on the request of any priority
|
||||
|
||||
b)RESET MR - a clearing the register of the mask(zeroizing all
|
||||
digits of the register of the mask); as a result
|
||||
all interruptions will be unmasked.
|
||||
|
||||
c)RESET IR - clearing of the register of the interruption.
|
||||
|
||||
2)CLR - a command of bitwise cleaning of internal registers of the chip;
|
||||
it is used to registers of the interruptions and masks:
|
||||
|
||||
a)IR - can be realized by signals from data buse, register of the
|
||||
mask and register of the vector. For exemple:
|
||||
|
||||
CLR IR ,00011000% ; \clean 4 and 5 digits
|
||||
CLR IR , MR; \clean that digits of the register of the
|
||||
\interruptions, for which the numeral in
|
||||
\ register of the mask corresponds
|
||||
CLR IR , VR ; \occurs zeroizing those of IR ,
|
||||
\which corresponds with the vector of the
|
||||
\interruptions,located in register of the vector
|
||||
|
||||
b)MR - realized by signals from data buses.
|
||||
|
||||
3)SET - is a command of the bitwise installing of the register of the mask.
|
||||
For instance:
|
||||
SET MR , 11100000%;\masking hte interruptions,
|
||||
\which enter from 8,7 and 6 external devices;
|
||||
\the rest of digits of the register of the mask
|
||||
\are not touched
|
||||
|
||||
4)READ - a command of the reading of the register m/c;
|
||||
it is used to registers of the mask, of the condition and of the
|
||||
vector:
|
||||
|
||||
a)READ MR;
|
||||
|
||||
b)READ SR;
|
||||
|
||||
c)READ VR;
|
||||
|
||||
While these commands are executing the signals, reflecting by
|
||||
condition of register of the mask, conditions and vector, are
|
||||
given on data bus.
|
||||
|
||||
5)DI - a prohibition of the request of the interruptions(occurs zeroizing
|
||||
of the trigger of the permiting of the request of the interruption).
|
||||
(command is without operands)
|
||||
6)EI - the permittion of the request of the interruption; the command acts
|
||||
opposite command DI. (command is without operands)
|
||||
|
||||
For all commands, where as second operand appears numerical value, shortcut
|
||||
form is also equitable - without direct inputting of the data; then the data
|
||||
will enter on data bus not from the memory of the microinstructions, but
|
||||
forming in process of the performing of the microinstruction on the kit of
|
||||
the microprocessor. For instance:
|
||||
|
||||
{OE_ALU; \allow the issue of the result of the execution
|
||||
\of operation on data bus in ALU
|
||||
XOR R1,R4; \execute the operation in ALU
|
||||
CLR MR; } \clean those digits of the register of the mask
|
||||
\that correspond to digits R1 and
|
||||
\R4 of ALU and do not coincide
|
||||
|
||||
All commands, which read or give on data bus some values, work from younger
|
||||
digits of the bus; for instance, the command
|
||||
|
||||
READ VR;
|
||||
|
||||
will issue the value of 3-digital register of the vector on three younger
|
||||
digits of the data bus.

9. Command of the loading of the LOAD register.
|
||||
══════════════════════════════════════════
|
||||
|
||||
The given command differs from all other commands of accembler, because it
|
||||
assigns the loading of the official registers, that refer to many nodes of the
|
||||
complex of the microprocessor. Depending on the operand that follows after the
|
||||
command, it can be with one or two operands:
|
||||
|
||||
1)The loading of the register of the inputting of the operand of the block
|
||||
of the ALU:
|
||||
|
||||
LOAD RA;
|
||||
LOAD RB;
|
||||
|
||||
the given command does not require as second operand to indicate the
|
||||
source of the loading or direct operand, because as hardware registers
|
||||
are connected to data bus and after presenting the signal record the
|
||||
value will be loaded in them, which is at present found on bus.
|
||||
|
||||
2)loading of registers of the marks of the controller of shifts:
|
||||
|
||||
LOAD RM;
|
||||
LOAD RN;
|
||||
here as the second operand it is possible to indicate necessary values:
|
||||
|
||||
1)Z - loading in all four marks the register of the zeroes;
|
||||
|
||||
2)NZ- loading in all four marks the register of the numeral;
|
||||
|
||||
3)FLAGS - loading in registers signs of execution of last
|
||||
operation in block ALU; with using the operator of the modification
|
||||
@ flags will be loaded in modified type (refer to table of the
|
||||
loading registers of marks);
|
||||
|
||||
besides it is possible to load one register by another. The Examples:
|
||||
|
||||
LOAD RM,Z;
|
||||
LOAD RN,RM;
|
||||
XOR R1,R5;
|
||||
LOAD RM,FLAGS;
|
||||
|
||||
The rest of the types of the loading of registers of marks are available
|
||||
when the command FIELD is in a use.
|
||||
|
||||
3)The loading of the registers of the mask and conditions of the block of
|
||||
the processing of the interruptions.
|
||||
The Command can be with one or two operands. The Difference is that in
|
||||
one operanded command registers are loaded by current information from
|
||||
data bus while under direct inputting of the operand of the loading, it
|
||||
is brought in the data field of microinstruction and is read on data bus
|
||||
from there. For instance:
|
||||
|
||||
LOAD SR,7; \register of the condition is with 3 digits,
|
||||
\remember that attempt to load there number
|
||||
\greater then 7 will cause a mistake\
|
||||
INC R1;
|
||||
LOAD MR; \load in register of the mask
|
||||
\the incremented value of the register
|
||||
\R1(more exactly the younger 8 digits)

||||
microprocessor complex different official signals, as the signals of the permit
|
||||
(forbid) of the issue of the data on the exits of the chip or record in
|
||||
internal registers etc. All these commands are especially specialized and have
|
||||
no operands. The Influence turns on those fields of microcommand, which are not
|
||||
touched by other groups of the commands.
|
||||
|
||||
1) The command of management of arithmetic-logical device on m/c BC1:
|
||||
|
||||
1. OEY - allow the issue of the result of operations in ALU on data bus;
|
||||
by default the issue of the data is suppressed.
|
||||
|
||||
2) The command of device management of shift management on m/c BP2:
|
||||
|
||||
1,2. CEM,CEN - a commands of the permition of recording to registers RM and RN;
|
||||
3..6. CEM_C,CEM_Z,CEM_N,CEM_V - writing the mark C(Z,N,V) in register of
|
||||
the marks RM.
|
||||
|
||||
3) The Commands of management of device management on m/c BY4:
|
||||
|
||||
1. RLD - a permition of the recording in register of the address/counter
|
||||
2. CCE - a permition of the presenting the condition
|
||||
3. CI - a prohibition of the forming the address of the following command;
|
||||
|
||||
4) The commands of the management of the device of the processing of the
|
||||
interruptions on m/c BH1:
|
||||
|
||||
1. EV - a permition of the issue of the address of the device of the
|
||||
interruptions on data bus
|
||||
|
||||
5) The commands of the management of the external devices and memory:
|
||||
|
||||
1. R - a command of the reading from memory
|
||||
2. W - a command of the recording in memory
|
||||
3. IN - a command of the reception from the external device
|
||||
4. OUT - a command of the recording in external device
|
||||
5..6. EWH,EWL - a commands of the recording in senior and younger digits
|
||||
of the register of the address accordingly. Two commands are incorporated for
|
||||
event, when number of digits BD < BA and write the new address in register of
|
||||
the address for one tact is impossible. Then the younger part of the address
|
||||
on data bus is formed, and, after making the signal EWL it writes in the
|
||||
register of the address, and then with senior part of formed address do the
|
||||
same.
|

12. Directives of the assembler.
|
||||
══════════════════════════════
|
||||
|
||||
The Directives does not translate in executive codes. They serve as pointers
|
||||
of assembler on that or other action which it must do with operands, attached to
|
||||
the directive. We shall consider the directives, supported by assembler
|
||||
"COMANDOR" and rules of the work with them:
|
||||
Following directives will are considered In this part:
|
||||
|
||||
12.1. Directive of including in translated text INCLUDE.
|
||||
12.2. Directive of accomodations of the executive code ORG.
|
||||
12.3. Directive of input of mark and(or) of the correspondence to EQU.
|
||||
12.4. Directive of input of macros.
|
||||
12.5. Directive of input of values of determined cells of memory DW.
|
||||
12.6. Directive of installation of internal registers of complex ACCEPT.
|
||||
12.7. Directive of input of switchings of the conditions for BMM LINK.
|
||||
|
||||
12.1. The Directive of the including of translated text INCLUDE.
|
||||
────────────────────────────────────────────────────────────
|
||||
|
||||
INCLUDE (+) - a directive of the insertion in translating program of the text
|
||||
from indicated file. The File assigned in directive must be in the same
|
||||
directory, as translating file. The Example:
|
||||
|
||||
include macro.lib
|
||||
+ routine
|
||||
|
||||
12.2. Directive of the accomodation of the executive code ORG.
|
||||
────────────────────────────────────────────────────────────
|
||||
|
||||
ORG ($) - a directive of the accomodation of the executive code indicates to
|
||||
the assembler on that nearest following after directive microinstruction will
|
||||
be situated in memories of the microinstructions by adress, specified after
|
||||
directive ORG. The Address must not exceed the last addressed field of the
|
||||
microinstructions. For instance:
|
||||
|
||||
org 010h
|
||||
org start
|
||||
$ 100
|
||||
|
||||
12.3.Directive of input of the mark and(or) of the correspondence to EQU.
|
||||
──────────────────────────────────────────────────────────────────────
|
||||
|
||||
EQU (=) - a directive of the inputting of the marks and correspondence need
|
||||
for You if You want to change any numeric constant or standard mnemonics of the
|
||||
assembler on clearer equivalent for You. The inputting of the mark is realized
|
||||
by writing the keyword EQU(=), name of the mark and by operator of division ":"
|
||||
of equivalent of the mark.
|
||||
For instance:
|
||||
|
||||
equ start : 10
|
||||
= add :add equ op1 : r1
|
||||
equ op2 : 10
|
||||
$ start
|
||||
{add op1,op2;}
|
||||
|
||||
12.4. Directive of the inputting of the macros MACRO.
|
||||
─────────────────────────────────────────────────
|
||||
|
||||
MACRO (#) - a directive of the inputting of macros allows You to construct
|
||||
your own commands and use them in the same way easy, as standard commands of
|
||||
the assembler. The Directive of macros is assigned by keyword MACRO, name of
|
||||
macro with enumeration of all its formal parameters and, by operator of division
|
||||
":" - the macro, executed in the manner of standard command of the assembler
|
||||
that is to say, inside of operators "{ }".
|
||||
For instance:
|
||||
|
||||
MACRO inc reg :{ add reg, reg, z, not z; }
|
||||
# JC cond, addr:{ Field Const addr, 0; CJP cond; }
|
||||
# dec_RgQ :{ sub Rq, Rq, z, not z; }
|
||||
|
||||
The Name of macro becomes usual standard mnemonics for translator with all
|
||||
spreading rights on it. The Names of formal operands of macro can`t be reserved
|
||||
mnemonics. In program a macro is assigned by its name and, real operands
|
||||
enumerated through comma in the same order, as it was inputed.
|
||||
For instance:
|
||||
|
||||
{ inc r4; jc not co, start;}
|
||||
.......
|
||||
|
||||
start {dec_RgQ;}
|
||||
|
||||
12.5. Directive of the input of values of determined cells of memory DW.
|
||||
────────────────────────────────────────────────────────────────────
|
||||
|
||||
DW - directive of the inputting of anyy cells of memory from lower 256
|
||||
addresses (0..255), as well as random 32 cells of memories from the general
|
||||
address space by amount of 2Mbytes by necessary values. For instance:
|
||||
|
||||
dw 03Fh:15
|
||||
dw 124:1,2,3,4,5 \put into cells with address
|
||||
\beginning from 124 numbers 1,2,3,4,5
|
||||
|

12.6. Directive of installation of internal registers of complex ACCEPT.
|
||||
───────────────────────────────────────────────────────────────────
|
||||
|
||||
ACCEPT - a directive of the installation ACCEPT will help You immediately to

|
||||
ACCEPT RDM_DELAY : 3
|
||||
will install speed to memories in 3 machine tacts
|
||||
|
||||
12.7. Directive of inputting of switchings of conditions for BMM LINK.
|
||||
───────────────────────────────────────────────────────────────────
|
||||
|
||||
LINK (&) - a directive of the inputting of the adjusting the connections of
|
||||
the kit allows the programmer to produce all necessary adjusting of the
|
||||
system right in program:
|
||||
12.7.1. Adjustments of the recording in register of the address.
|
||||
12.7.2. Inputting the address of transition by vector of interruptions.
|
||||
12.7.3. Adjustments of converter of address of the microinstruction.
|
||||
12.7.4. Adjustments of the buffer V.
|
||||
12.7.5. Adjustments of enters of the multiplexor of the conditions.
|
||||
12.7.6. Adjustments of registers of the inputting of operands in ALU.
|
||||
|
||||
12.7.1. Adjustment of the recording in register of adress.
|
||||
───────────────────────────────────────────────────────
|
||||
In given system the register of the address has 20 bits that with 16 bits
|
||||
data bus requires two cycles of recording of information in this register; so
|
||||
the register is devided into two parts, each of which controls by own signal
|
||||
of recording:
|
||||
- EWH for writing in senior part,
|
||||
- EWL - in younger.
|
||||
While adjusting the system it is necessary to assign the youngest bit of
|
||||
recording by signal EWH that is to say, to assign the amount of bitt, written
|
||||
by this signal. So that it can be written only for 16 bits, that, accordingly,
|
||||
the starting bit can be from 4-th to 16-th inclusive.
|
||||
For instance:
|
||||
|
||||
LINK EWH : 11 \adjust the recording in register of the address
|
||||
\so as it will be recorded 10 bits of
|
||||
\senior and younger
|
||||
\parts of address accordingly by
|
||||
\sinlals EWH or(and) EWL
|
||||
|
||||
12.7.2. Inputting of address of transition by vector of interruptions.
|
||||
───────────────────────────────────────────────────────────────────
|
||||
There is the possibility in system at appearance of inquiry for interruption
|
||||
from one of 8 external devices to give on data bus the address of transition on
|
||||
corresponding subprogramms of the processing of the interruption. 8 addresses
|
||||
are kept in converter of the exit of the block of the priority interruptions,
|
||||
presenting from itself the ROM 16*16. The enterence for given ROM is a vector
|
||||
of external device VEC[0]..VEC[7]. The inputting of the address of the
|
||||
transition is possible to realize for each vector apart,and also for all
|
||||
vectors together:
|
||||
|
||||
LINK VEC[3] : 0CDEFh
|
||||
LINK VEC : 1111h,2222h,3333h,4444h,
|
||||
5555h,6666h,7777h,8888h
|
||||
|
||||
The Maximum address of the inputting - 0FFFFh.
|
||||
|
||||
12.7.3. Adjusting the converter of the address of microinstruction.
|
||||
──────────────────────────────────────────────────────────────
|
||||
There is a possibility to give on internal bus of the address of the
|
||||
microinstruction the address with buses of the data moreover in free order of
|
||||
the following of bits through 12-digits buffer M . The inputting is realized
|
||||
by consequent enumeration of 12 connected on exits of the buffer from 11 to 0
|
||||
wires from data bus from 0 to 15, for instance:
|
||||
|
||||
LINK M : 4,5,6,7,8,9,10,11,12,13,14,15
|
||||
|
||||
12.7.4.Adjusting the buffer V.
|
||||
───────────────────────────
|
||||
There is possibility to give on internal bus of the address of the
|
||||
microinstruction directly signals of inquiry for interruption IRQ0..IRQ7, the
|
||||
code of the condition CT, the general interruption INT, readiness of memories
|
||||
and external devices RDM and RDD, as well as signals Z and NZ through 12 digits
|
||||
buffer V .
|
||||
When adjusting You necessary to enumerate all 12 connected signal, for
|
||||
instance: LINK V : Z,NZ,IRQ0,IRQ1,IRQ2,IRQ3,
|
||||
IRQ4,IRQ5,IRQ6,IRQ7,CT,INT
|
||||
|
||||
12.7.5. The adjustment of enterings of the multiplexor of conditions.
|
||||
─────────────────────────────────────────────────────────────────
|
||||
On the entering of the multiplexor of the conditions L[1]..L[6] it is
|
||||
possible to give the signals of inquiry for interruption IRQ0..IRQ7, of the
|
||||
code of the condition CT, the general interruption INT, readiness of the memory
|
||||
and external devices RDM and RDD, as well as signals Z and NZ. The inputting is
|
||||
realized apart how for each entering the conditions,and so the general,
|
||||
for instance: LINK L : CT,INT,IRQ0,IRQ1,IRQ2,IRQ7
|
||||
LINK L[3]: CT
|
||||
|
||||
12.7.6. Adjustment of registers of inputing of operands of ALU.
|
||||
────────────────────────────────────────────────────────────
|
||||
4 digits registers of ALU RA and RB allow to give on entering of the choice
|
||||
of operands in ALU the data directly from data bus moreover the switching of
|
||||
the wires of data bus on the entry of registers can be free and is assigned.
|
||||
Adjustment of switchings of wires is realized similarly as adjusting of the
|
||||
buffer M, for instance:
|
||||
|
||||
LINK RA : 11,12,13,14
|
||||
LINK RB : 10,9,8,7
