If memory accesses take 100 times more than register accesses, then a LOAD instruction will take ___ machine cycles than an ADD DR, SR1, SR2 instruction.

If memory accesses take 100 times more than register accesses, then a LOAD instruction will take more machine cycles than an ADD DR, SR1, SR2 instruction

Explanation

There are different modes of instructions access from different input terminals or some memory addresses. Memory access and register access are also the mode of instruction access from different memory locations. In Memory access the data or instructions are directly fetched from some memory locations while in register access mode data is fetched through the registers.

Machine Cycle consist of of steps to execute the instructions that steps includes: Fetch, Decode, Execute, Write. Memory access mode takes more machine cycles than register access.

Load instruction is a machine access instruction because it directly load data from memory. ADD DR, SR1, SR2 instruction is Register access because it access data from registers SR1 and SR2.

So, If memory access take 100 times more than register access, then Load instruction will take more machine cycles than ADD DR, SR1, SR2.
