Show execution trace for each sequence of instructions on a five$-$stage pipelined processor with early

branch resolution and full forwarding $($i$.$e$.$ M$-$D$,$ M$-$X$,$ and W$-$X forwarding$).$

Indicate the pipeline stage of each instruction for each clock cycle with the corresponding letter, as

done in the first instruction of the first sequence

Indicate the forwarding of operands with downward arrows in the forwarding cycle from the

producing instruction to the consuming instruction

Complete all rows, but all columns may not necessarily be used
