Problem $3)$

We want to compare two implementations of the multiplication operation using the SimARM

instruction set.

a$)$ Write a SimARM assembly code that reads two $32-$bit values a and $b$ stored in memory and

puts the result in a $32-$bit variable product in memory.

b$)$ Assuming the SimARM instruction set does not have a multiplication instruction, we want to

perform the multiplication operation using addition in a loop.

Convert the following $C$ code into SimARM assembly program, which reads two signed $32-$

bit numbers stored in memory and computes their product.

c$)$ Compare the code size and of both implementations.

d$)$ Assuming load and store instructions to consume $25$ clock cycles, branch instructions $12$ clock

cycles and all other instructions $15$ clock cycles, compare the execution times of both

implementations.
