See below.
Next, set a flag (register $14) if the array entry is
negative.
Branch to the symbolic address
neg
if it is.
## Registers:
## $8 --- count $12 -- sum of negative integers
## $9 --- pointer to the array entry $13 -- sum of positive integers
## $10 -- current array entry $14 -- pos. or neg. flag
## $11 -- sum of all integers $15 -- SIZE of the array
# while count < SIZE do
loop: beq $8,$15,done
sll $0,$0,0 # branch delay
# get entry, add to sum
lw $10,0($9) # get entry
sll $0,$0,0 # load delay
addu $11,$11,$10 # add to sum
# test neg. or pos.
slti $14,$10,_____ # set flag if entry is neg
bne $___,$___,neg # branch if negative
sll $0,$0,0 # branch delay
neg:
addiu $8,$8,1 # count++
addiu $9,$9,4 # point at next entry
j loop
sll $0,$0,0 # branch delay
done: sll $0,$0,0 # target for branch
