Memory of the microinstructions of the designed system contains
|
||
|
|
separate microinstructions, each divided on fields:
|
||
|
|
|
||
|
|
1. Field of constants:
|
||
|
|
address MCU (microprogramming control unit);
|
||
|
|
constant ALU (arithmetical and logical unit);
|
||
|
|
2. Field of the ALU :
|
||
|
|
chip KM1804 BC1;
|
||
|
|
chip KM1804 BP2;
|
||
|
|
registers of the address operands RAA,RAB;
|
||
|
|
3. Field of the MCU (microprogramming control unit):
|
||
|
|
chip KM1804 BY4;
|
||
|
|
conditions multiplexer;
|
||
|
|
4. Field of the PIU (priority interruption unit);
|
||
|
|
chip KM1084 BH1;
|
||
|
|
5. Field of the control signals:
|
||
|
|
MM - main memory;
|
||
|
|
IOD - input / output device;
|
||
|
|
RA - register of address.
