Problem $8$:

Consider the following program segment:

START: LDUR X$10,[$X$1,$ #$0]$

LDUR X$11,[$X$1,$ #$8]$

ADD X$12,$ X$10,$ X$11$

SUBI X$1,$ X$1,$ #$16$

CBNZ X$12,$ START

Let us assume there is no control hazard.

a$)$ Is there a data Hazard? Identify the instructions that are involved with that hazard if any.

b$)$ Show a five stages pipeline execution diagram for the first two iterations of the above program segment.

c$)$ Mark the pipeline stages that do not perform useful work. Please answer these questions as specified show work!! thnk you!
