Objective:

Write C code to calculate the performance of a program with dependent arithmetic instructions

on a $5-$stage pipeline architecture. The five stages are: Instruction Fetch $($IF$),$ Instruction Decode

$($ID$),$ Execution $($Ex$),$ Memory access $($ME$),$ and Write$-$Back $($WB$)$

Inputs:

$*$ Number of instructions in the program

$*$ Set of instructions

Outputs:

$*$ A chart of the pipelined stages of the instructions

$*$ The total cycle count for the program

Specification:

The program calculates the output based on choosing from a menu of choices, where each

choice calls the appropriate procedure, where the choices are:

Enter instructions

Print a chart of the pipelined stages of the instructions

Print the total cycle count for the program

Quit

You can use any editor an$($d$)/($o$)$r compiler, but make sure your code compiles and executes under the gcc compiler in the Unix environment.

Example:

$ a$.$out
