Math Calculations in MIPS Assembly Assignment Sample

Write a program to solve the equation (3x+7)(2x+8), try with initial values of 0, 1 for x as that will make it easier to debug. Evaluate the expression 17xy – 12x – 6y + 12. Use symbolic addresses for x, y and answer. Write a program to calculate the average value of a byte array. Sum all the values from 1 to 100 using a loop.

Solution:

q1.asm

.text
main:
addi $t0, $0, 10 #storing the x
addi $t1, $0, 3
addi $t2, $0, 2
mult $t1, $t0 #3x
mflo $t3
addi $t4, $t3, 7 #3x+7
mult $t0, $t2 #2x
mflo $t5
addi $t6, $t5, 8 #2x+8
div $t7, $t4, $t6 #(3x+7)/(2x+8)
add $10, $t7, $0 #storing in $10 register
