the course is microprocessor

11. The machine code for instruction STD $3088 is (7C, 30, 88). (Assuming data bus is 8 bit.) (4 pts) (1) How many memory accesses are needed for fetching this instruction to CPU? (2) How many memory accesses are required to execute this instruction? (3) Explain in detail what happens in the computer during each memory access. 12. The machine code for instruction LDD $3088 is (FC, 30,88). (Assuming data bus is 16 bit.) (4 pts) (1) How many memory accesses are needed for fetching this instruction to CPU? (2) How many memory accesses are required to execute this instruction? (3) Explain in detail what happens in the computer during each memory access. 13.
