2 Five Instruction Steps ) Instruction Fetch ) Instruction Decode and Register Fetch 3) R-type Instruction Execution, /Write Address Computation, Branch Completion, or Jump Completion 4) Access, Write Completion or R-type Instruction Completion 5) Completion (Write Back) INSTRUCTIONS TAKE FROM 3-5 CYCLES!
3 RTL for Instructions Common Steps: Instr fetch IR = [PC]; PC Updating PC = PC + 4; Decode and Register reading A = Reg[IR[5-]]; B = Reg[IR[-6]]; Instruction Dependent operation 3
4 RTL Summary Step R-type Mem Ref Branch Jump Instr fetch Decode Execute Out = A op B; access Writeback IR = [PC]; PC = PC + 4; A = Reg[IR[5-]]; B = Reg[IR[-6]]; Out = PC +(sign-extend(ir[5-])<< ); Reg[IR[5 -]] = Out; Out = A + sign-extend (IR[5-]); MDR = [Out]; or [Out] = B; Reg[IR[-6]] = MDR; if (A==B) PC = Out; PC = PC[3-8] (IR[5- ] << ); 4
5 Step : Instruction Fetch Use PC to get instruction from the memory and put it in the Instruction Register Increment the PC by 4 and put the result back in the PC Can be described succinctly using the RTL "Register- Transfer Language IR = [PC]; PC = PC + 4; Can we figure out the values of the control signals? What is the advantage of updating the PC now? 6

7 Fetch Control Signals Settings Unless otherwise assigned Start,IRWrite, MemWrite,RegWrite= others=x IorD= Instr Mem;IRWrite Fetch SrcA= srcb= PCSource,Op= 8
8 Step : Instruction Decode and Register Fetch Don t know what the instruction is yet, so can only registers rs and rt in case we need them Compute the branch address in case the instruction is a branch The RTL: A = Reg[IR[5-]]; B = Reg[IR[-6]]; Out = PC+(sign-extend(IR[5-])<< ); Note we aren't setting any control lines based on the instruction (since we don t know what it is (the control logic is busy "decoding" the op code bits)) 9

11 Step 3 Instruction Dependent Operations is performing one of four functions, based on instruction type reference (lw and sw): Out = A + sign-extend(ir[5-]); R-type: Out = A op B; Branch: if (A==B) PC = Out; Jump: PC = PC[3-8] (IR[5-] << );
12 Datapath Activity During lw & sw Execute Cond IorD Mem MemWrite MemtoReg IRWrite PCSource Op Control SrcB SrcA RegWrite RegDst PC Address Data (Instr. or Data) IR MDR Instr[3-6] Instr[5-] Instr[5-] Addr Register Addr Data File Write Addr Sign Extend 3 Instr[5-] Data left A B 4 3 PC[3-8] left zero control 8 out 3

15 Datapath Activity During j Execute Cond IorD Mem MemWrite MemtoReg IRWrite PCSource Op Control SrcB SrcA RegWrite RegDst PC Address Data (Instr. or Data) IR MDR Instr[3-6] Instr[5-] Instr[5-] Addr Register Addr Data File Write Addr Sign Extend 3 Instr[5-] Data left A B 4 3 PC[3-8] left zero control 8 out 6

17 Step 4 (also instruction dependent) reference: MDR = [Out]; -- lw or [Out] = B; -- sw R-type instruction completion Reg[IR[5-]] = Out; Remember, the register write actually takes place at the end of the cycle on the clock edge 8
18 Datapath Activity During lw Access Cond IorD Mem MemWrite MemtoReg IRWrite PCSource Op Control SrcB SrcA RegWrite RegDst PC Address Data (Instr. or Data) IR MDR Instr[3-6] Instr[5-] Instr[5-] Addr Register Addr Data File Write Addr Sign Extend 3 Instr[5-] Data left A B 4 3 PC[3-8] left zero control 8 out 9

22 Step 5: Completion (Write Back) All we have left is the write back into the register file the data just read from memory for lw instruction Reg[IR[-6]]= MDR; What about all the other instructions? 3
23 Datapath Activity During lw Write Back Cond IorD Mem MemWrite MemtoReg IRWrite PCSource Op Control SrcB SrcA RegWrite RegDst PC Address Data (Instr. or Data) IR MDR Instr[3-6] Instr[5-] Instr[5-] Addr Register Addr Data File Write Addr Sign Extend 3 Instr[5-] Data left A B 4 3 PC[3-8] left zero control 8 out 4
