Problem $1$

A compiler designer is trying to decide between two code segments for a particular machine. The hardware designers have provided the following data below about the CPI for each class, and the instruction counts being considered for each code sequence.

$\backslash$table$[[,\backslash$table$[[$Instruction Counts$],[$for Instruction$],[$Classes$]]],[$Code sequence,A$,$B$],[1,3,5],[2,7,2]]$

$\backslash$table$[[$Class$,\backslash$table$[[$CPI for this instruction$],[$class$]]],[$A$,2],[$B$,3]]$

a$.$ How many cycles are required for each code sequence?

Code sequence #$1$:

Code sequence #$2$:

b$.$ Which is faster and how by how much?

c$.$ What is the CPI for each code sequence?

CPI for code sequence #$1$:

CPI for code sequence #$2$:
