Assume using sequential ALU. This processor is going execute 'sll r10, r5, 10' next. How many cycle will this processor take to complete this instruction?
Homework Answers
There will be 4 cycles taken by sequential ALU on instruction "sll r10,r5,10" in which in first cycle, instruction fetch will take place, then in next cycle instruction decode will take place where the type of instruction will be decoded, then in execute instruction phase shifting of content of register r5 by 10 bits will take place, finally in 4th cycle, the result will be copied back into register r10.
Please comment for any clarification.
