Question

When designing a 4-bit microcomputer from TTL ICs, you decide to incorporate the following instructions: LDA data, STA data, HLT, ADD data, SUB data. JMP address and INA (increment accumulator). To minimize the complexity, you want to use a program counter IC which has only those capabilities absolutely necessary to run a program beginning at memory location 0000. Which of the following functions would NOT be required by the program counter in the microcomputer?

1) increment program counter (3) clear program counter 2) decrement program counter (4) parallel load program counter

Explanation / Answer

want to make control unit for 4 bit cpu I know control unit is made of many other circuit such as decoder ,multiplexer timer but I am confused which circuit make control unit for cpu

1)how to decide which logic circuit is used to make control unit for cpu
2)what circuit component I need to make control unit (i think basic gates)
3) what should I need to know before to make control unit for cpu

please anyone give me idea how to make control unit for cpu

The only answers to your questions I can suggest are:

1) There is no single logic circuit.

2) There is no circuit component. If you want to create a single chip solution you would have to use an FPGA.

3) You need to study combinational and sequen
