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 $10, %rdx mrmovq 8(%rdx), %rbx Cycle/ Instruction 4 irmovq F $10, mrmovq 8 (%rdx), (f 1) f 1 (Cycle 3): Forwarding occurs at Decode stage of cycle 3 Source operand of instruction mrmovq 8 (%rdx), %rbx in decode stage (d srcB-%rdx) is stored by previous instruction irmovq $10, %rdx (e-destE-%rdx), therefore execute stage of previous instruction forwards result (e valE 10) main: irmovq $256, %rsp irmovq $2, %rdx pushq %rax irmovq $10, %rbx popq %rax addq %rbx, %rax andq %rax,%rax je end call proc halt proc: ret # do nothing end: halt Q2) Draw pipeline diagram for given sequence of code.
