Which new control signals must be added to your pipeline from 4.15.1?

Problem 4.15.1

What must be changed in the pipelined datapath to add this instruction to the MIPS ISA?

In this exercise, we examine how the ISA affects pipeline design. Problems in this exercise refer to the following new instruction:

a. b. ADDM Rd, Rt+Offs (Rs) BEQM Rd, Rt, Offs (Rs) Rd=Rt+Mem[Offs+Rs] if Rt=Mem[Offs+Rs] then PC = Rd
