1. This exercise is intended to help you understand the relationship between forwarding, hazard detection, and ISA design. Problems in this exercise refer to the following sequence of instructions, and assume that it is executed on a 5-stage pipelined datapath: add r5,r2,r1 lw r3,4(r5) lw r2,0(r2) or r3,r5,r3 sw r3,0(r5) (a) If there is no forwarding or hazard detection, insert nops to ensure correct execution. (b) Repeat (a)but now use nops only when a hazard cannot be avoided by changing or rearranging these instructions. You can assume that register R7 can be used to hold temporary values in your modified code.

Transcribed Image Text:1. This exercise is intended to help you understand the relationship between forwarding, hazard
detection, and ISA design. Problems in this exercise refer to the following sequence of
instructions, and assume that it is executed on a 5-stage pipelined datapath:
add r5,r2,r1
lw r3,4(r5)
lw r2,0(r2)
or r3,r5,r3
sw r3,0(r5)
(a) If there is no forwarding or hazard detection, insert nops to ensure correct execution.
(b) Repeat (a)but now use nops only when a hazard cannot be avoided by changing or rearranging these
instructions. You can assume that register R7 can be used to hold temporary values in your modified code.
