1. Assume that registers $s0 and $s1 hold the values 0x80000000 and 0xD0000000, respectively. a.) [5 points] What is the value of $t0 for the following assembly code? add $t0, $s0, $s1

b.) [5 points] Is the result in $t0 the desired result, or has there been overflow?

c.) [5 points] For the contents of registers $s0 and $s1 as specified above, what is the value of $t0 for the following assembly code? sub $t0, $s0, $s1

d.) [5 points] Is the result in $t0 the desired result, or has there been overflow? e.) [5 points] For the contents of registers $s0 and $s1 as specified above, what is the value of $t0 for the following assembly code? add $t0, $s0, $s1

f.) Is the result in $t0 the desired result, or has there been overflow?

2. For the MIPS assembly instructions below, what is the corresponding C statement? Assume that the variables f, g, h, i, and j are assigned to registers $s0, $s1, $s2, $s3, and $s4, respectively. Assume that the base address of the arrays A and B are in registers $s6 and $s7, respectively.

sll $t0, $s0, 2 # $t0 = f * 4

add $t0, $s6, $t0 # $t0 = &A[f]

sll $t1, $s1, 2 # $t1 = g * 4

add $t1, $s7, $t1 # $t1 = &B[g]

lw $s0, 0($t0) # f = A[f]

addi $t2, $t0, 4

lw $t0, 0($t2) add $t0, $t0, $s0 sw $t0, 0($t1)
