1. Assume that we have C variables assigned to MIPS registers as follows: a =

$s0, b = $s1, c = $s2, d = $s3. Write MIPS assembly code that will implement the C

statement a = b (c + d);.

2. Now assume that we have C variables assigned to MIPS registers as follows:

a = $t0 and the base address of array X is stored in $t1. Assume that array X is stored in

main memory, with the base address referring to array element X[0].

Write MIPS assembly code that will implement the C statement X[10] = a;.

3. You are given the MIPS instruction sw $t0, 40($t1). Determine the binary representation of this instruction,

then convert to hexadecimal form.

4. What MIPS instruction does the following hexadecimal machine code represent?

0x012A4022

5.

Assume we have the following MIPS code, starting at memory address

1000H:

1000H	LOOP:	slt	$t2, $zero, $t1
1004H		beq	$t2, $zero, DONE
1008H		subi	$t1, $t1, 1
100CH		addi	$s2, $s2, 2
1010H		j	LOOP
1014H	DONE:

If we use PC relative addressing, what is the constant for DONE in the beq instruction?
