Flowchart

The flow chart could work for any language. Language details are left out of the design. The chart is a structured flowchart. Here is an outline of the program:

## addIntArray.asm
##
## Sum all integers, the positive integers,
## and the negative integers in an array.

## Registers:
## $8 --- count
## $9 --- pointer to the array entry
## $10 -- current array entry
## $11 -- sum of all integers
## $12 -- sum of negative integers
## $13 -- sum of positive integers
## $14 -- pos. or neg. flag
## $15 -- SIZE of the array

         .text
         .globl  main
# Initialize
main:    ori      $____,$0,0       #  count = 0
         ori      $____,$0,0       #  sum = 0
         ori      $____,$0,0       #  neg = 0
         ori      $____,$0,0       #  pos = 0

# while  count < SIZE do
loop:     
         . . . .
		 
         j        loop
         sll      $0,$0,0        #  branch delay

        .data
size:   .word  17
array:  .word  12, -1, 8, 0, 6, 85, -74, 23, 99, -30, 30, 95, 4, 7, 10, 28, 14

SPIM initializes registers to zero, but it is good practice to explicitly zero accumulators.
