Loading the Array Size

Next, load the size of the array into register $15. The size is the first word of the data section. Recall that the data section starts at the address 0x10000000. Load the top half of that address into the base register.

## 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

## Initialize
main:    ori      $8,$0,0        #  count = 0
         ori      $11,$0,0       #  sum = 0
         ori      $12,$0,0       #  neg = 0
         ori      $13,$0,0       #  pos = 0

         ____     $9,0x1000     #  point at SIZE
         ____     $15,0($9)     #  get SIZE
         addiu    $9,$9,____    #  point to first entry

# 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

Next, load SIZE into register $15. Finally, point the base register at the first word of the array.
