Drawing Pipeline Diagram

Q2) Draw pipeline diagram for given sequence of code. Assume we are using Y86-64 pipelined processor that handles data and control pipeline hazards by using forwarding and stalling. Also identify when forwarding takes place on "Decode" stage. Show how you identified forwarding and what value/values are being forwarded. (50 points) Example irmovq mrmovq $10, %rdx 8(%rdx), %rbx Cycle1 Instruction 2 4 irmovqF $10, %rdx mrmovq 8 (%rdx) (f 1) f 1 (Cycle 3): Forwarding occurs at Decode stage of cycle 3 Source operand of instruction mrmovq 8(Xrdx), %rbx in decode stage (dsrcB-%rdx) is stored by previous instruction irmovq $10, %rdx (e-destE %rdx), therefore execute stage of previous instruction forwards result (e_valE10) main: irmovq $256, %rsp irmovq $2, %rdx pushq %rdx irmovq $10, %rbx popq %rax addq %rbx, %rax andq %rax,Arax je end call proc halt proc: ret # do nothing end: halt Q2) Draw pipeline diagram for given sequence of code.
