For the following sequence of MIPS instructions. Explain your answers using the 5-stage pipeline.

Without Forwarding:

a) show the pipelining sequence and schedule the instruction in a 5 stage pipeline.

b) reorder the provided code to minimize stalls. (Your reordering shouldn't impact the semantics and end result of the code.

With Forwarding:

c) show the pipelining sequence

d) reorder the code to minimize the stalls.

e) compare with original (no forward) code. (# of total cycles and number of stall cycles.)
