Computer System Architecture - Microprogrammed Control
- Option : B
- Explanation : In typical RISC architecture, the STORE instruction is used to move the contents of a register to a memory location.
- Option : A
- Explanation : For the data transfer to take place, the data output of register R4 should
be enabled (R4out) and the data load control of R5 should be activated
(R5in).
- Option : A
- Explanation : Option A, C and D are correct.
When the control signals PCout and MARin are activated, the contents of PC will get transferred via the internal processor bus to the MAR register. And since READ is also active, the address in MAR will be used to initiate a read operation to memory to fetch the next instruction.
