Final answer:
The MIPS assembly code initializes a loop that compares variables 'i' and 'j', and within this loop, it stores the comparison result of 'a' and 'b' into the array D at the current index 'i'.
Step-by-step explanation:
The given C code suggests a loop that would iterate based on the changing value of i and compare it with the variable j. Within MIPS assembly, we would start the loop by setting i to 0, then continuously check if i is less than j, and within the loop, compare a with b and store the result in array D at the index i.
MIPS Translation
move $t0, $zero # i = 0
loop_start: bge $t0, $t1, loop_end # if i>=j, exit loop
sll $t2, $t0, 2 # t2 = i*4 (since an int is 4 bytes)
add $t2, $t2, $2 # t2 = address of D[i]
sle $t3, $s0, $s1 # t3 = (a <= b)
sw $t3, 0($t2) # D[i] = (a <= b)
addi $t0, $t0, 1 # i = i + 1
j loop_start # jump to start of loop
loop_end:
Please note that the sle instruction sets the destination register to 1 if the first source register is less than or equal to the second source register, and 0 otherwise. We then store this result into the appropriate index of array D.
