Question

3. Write a MIPS code that finds the highest value, lowest value and average of 10 numbers that are given as the global values (in the address range: 0×10000000 to 0×10000009) and stores them in the next addresses. Bonus (optional): Write a MIPS code module to sort the numbers in ascending order. Mention your sorting algorithm clearly.

Answer 1

MIPS PROGRAM:-

.data

.text

main:
   #$s0 = stores the address
   #$s1 = min
   #$s2 = max
   #$s3 = average

   li $s0, 0
   lui $s0, 0x1000
   li $s3, 0

#considering first address value to be min and max
   lw $s1, 0($s0)      
   add $s2, $zero, $s1      
   add $s3, $zero, $s1
  
   li $t0, 9   #count
loop:
   addi $s0, $s0, 1
   ble $t0, $0, LOOP_END
   lw $t1,0($s0)
   add $s3,$s3, $t1
   bge $s1, $t1, SKIP_MIN
   add $s1, $zero, $t1
SKIP_MIN:
   ble $s2, $t1, SKIP_MAX
   add $s1, $zero, $t1
SKIP_MAX:
   addi $t0, $t0, -1  
   j loop
LOOP_END:
   sw $s1,0($s0)   #stored min in 0x1000000A  
   addi $s0, $s0, 1
   sw $s2,0($s0)   #stored min in 0x1000000B
   addi $s0, $s0, 1
   li $t1,10
   div $s3, $t1
   mflo $s3
   sw $s3,0($s0)   #stored avg in 0x1000000B
Done:

li $v0, 10 #syscall to exit
syscall
