Question

The recorded temperatures in London during a period of 15 days was 18 degrees Celsius, 25 degrees Celsius,34 degrees Celsius,22 degrees Celsius,2 degrees Celsius, 43 degrees Celsius,30 degrees Celsius,20 degrees Celsius,08 degrees Celsius, 28 degrees Celsius, 24 degrees Celsius, 27 degrees Celsius, 40 degrees Celsius,29 degrees Celsius and 03 degrees Celsius. Write a program using MIPS to calculate the average temperature of the country during the month of December.

Answer 1

   .data

array: .word   18, 25, 34, 22, 2, 43, 30, 20, 8

       .word   28, 24, 27, 40, 29, 3

days:   .word   15

average: .word 0

 .text

.globl main

main:

# Loop through the array to calculate sum

   la $t0, array   # array starting address

   li $t1, 0       # loop index, i=0

   lw $t2, days   # days

   li $t3, 0       # initialize sum=0

sumLoop:

   lw $t4, ($t0)       # get array[i]

   add $t3, $t3, $t4    # sum = sum + array[i]

   add $t1, $t1, 1    # i = i+1

   add $t0, $t0, 4    # update array address

   blt $t1, $t2, sumLoop # if i<days, continue

# Calculate average

   div $t5, $t3, $t2    # average = sum / length

   sw $t5, average

   li $v0, 1          # print integer

   move $a0,$t5       # $a0 = sum

   syscall   

# Done, terminate program.

   li $v0, 10 # terminate

   syscall # system call
