Question: In the following MIPS assembly code, translate all the instructions to their corresponding machine code in hexadecimal format. This code is stored in the memory from address 0x2fff0004.
Loop: lw $t0, 4($s0)
addi $t1, $t1, -15
sll $t1, $t1, 2
beq $t1, $s1, Exit
addi $s0, $s0, 4
j Loop
Exit: …

Expert Solution
Please find the answer below::
LW $t0 0x0004 $s0
For the instruction, the format is as below
Binary: 10001110000010000000000000000100
Hex: 0x8e080004
2. addi $t1, $t1, -15
Instruction is as below
ADDI $t1 $t1 0xFFF1
Binary: 00100001001010011111111111110001
Hex: 0x2129fff1
3.
sll $t1, $t1, 2
Binary: 00000000000010010100100010000000
Hex: 0x00094880
4.
BEQ $t1 $s1 0x0002
Binary: 00010001001100010000000000000010
Hex: 0x11310002
5.
ADDI $s0 $s0 0x0004
Binary: 00100010000100000000000000000100
Hex: 0x22100004
6.
j Loop
Address of loop is : 0x2fff0004
IN binary it is:
101111111111110000000000000100
Converting to 26 bit it will be :
11111111111100000000000001
Adding 000010 as MSD for jump
SO complete instruction will be : 00001011111111111100000000000001
In hexa decimal it will be : 0xbffc001

Translate the C function code below to the MIPS True Assembler
Language code (machine instructions only). The function code should
follow the conventions for MIPS function calls including passing
parameters and returning results. Your function code must be
written with the minimum number of machine instructions to be
executed and without any use of MIPS pseudo-instructions.

int i=0;
while (a > c) {
a /= b;
