Consider the execution of the instruction "rmmovg $\%$ rax, $01124($rsp$)".$ Assume that

the data in register $\%$ rsp is $0456,$ the value of PC is $0360.$ Use $"$vm$"$ to represent the data that

will be written to the main memory.

Describe the steps done in the following stages: Fetch, Decode, Execute, Memory, Write Back,

PC update, by filling in the blanks in the table below.

Note that you are required to fill in the generic form of each step in the second column; and in

the third column, fill in the steps for the instruction "rmmovg $\%$ rax, $01124($rsp$)"$ with

the above given values.

The symbol $"$ larr $"$ means reading something from the right side and assign the value to the left

side. $x$:$Y_{?}$ means assign the highest $4$ bits of a byte to $x,$ and assign the lowest $4$ bits of the byte

to $Y.$

Answer:$3.$ Describe $4$ desirable characteristics of a benchmark program. $(2$ Marks$)4.(3$ Marks$)$ Consider the execution of a program that results in the execution of $2$ million instructions on a $800$ MHz processor. The program consists of four major types of instructions. The instruction mix and the CPI for each instruction type are given below, based on the result of a program trace experiment: Calculate the MIP rate of this machine.
