add SW addi bne The classic five-stage pipeline MIPS architecture is used to execute the code fragments in this problem. Assume the followings: The architecture fully supports forwarding, • Register write is done in the first half of the clock cycle; register read is performed in the second half of the clock cycle, • Branches are resolved in the third stage of the pipeline and the architecture does not utilize any branch prediction mechanism, • Register R4 is initially 100....
