Question $2$: Loop unrolling and Static Multi$-$issue $(20$ points$)$

Assume that you are given a dual$-$issue pipeline for RISC$-$V ISA. You can schedule ALU or branch

instruction in the first issue slot, and load$/$store instruction in the second issue slot of the issue

package. You are given the following sequence of instructions.

Loop:

a$)[10$ points$]$ Assume that the loop index for the given loop above is divisible by $3.$ Unroll the

given loop $3$ times. Use register renaming as necessary to avoid any name dependencies.

b$)[10$ points$]$ How would the unrolled loop in $($a$)$ be scheduled on the given static dual$-$issue

pipeline? You may use the following template to show the schedule.
