For this problem, just implement the described instructions (datapath and control modifications) on the single-cycle datapath. Assume that Load With Increment will be an R-type instruction, and Swap and Store Sum will be I-type instructions.

Note that the Store Sum instruction should be Mem[Reg[rt]]=Reg[rs]+SignExtend(immediate)

4.11 Examine the difficulty of adding a proposed lwi.drd, rsi, rs2 (Load With Increment) instruction to MIPS. Interpretation: Reg[rd] Mem[Reg[rs1] + Reg[rs2]] = 4.11.1 [5] Which new functional blocks (if any) do we need for this instruction? 4.11.2 [5] Which existing functional blocks (if any) require modification? 4.11.3 [5] Which new data paths (if any) do we need for this instruction? 4.11.4 [5] What new signals do we need (if any) from the control unit to support this instruction
