Question $2[30$ points$]$

Given $3$ MIPS assembly programs and they are executed in a $5-$stage pipeline processor. Answer the following questions:

$($a$)$ Identify the type of hazards for each program.

$($b$)$ Identify all the data dependencies for each program

$($c$)$ Consider the program in $($iii$),$ and answer the following questions, $[$assuming there is no structural hazard$]$

i$.$ Assume that only "nop" instruction can be added to resolve the data hazard, how many "nop" instructions are needed?

ii$.$ Draw the pipeline diagram with the hardware methods that are taught during the lecture to resolve only the data hazard$($s$)$ found in part $($a$)$ for the program $($iii$).$

iii. What is the speedup factor when comparing the methods in part c$($i$)$ and part c$($iii$)?$ Which one is more efficient?
