Question

There are two programming questions for you to do. Please submit two .s or .asm files 1. (5 points) There is one two's complement integer in the data section with symbolic addresses X. If x is even, replace with r +1. If z is odd, replace r with r+2 A sample data section is as follows. x 1s odd, replace z with 2 2 data x: word 2

Answer 1

Please find the code below::::

.data
x : .word 2

.text
lw $t0,x #load value of x

div $t1,$t0,2 #divide by two
mfhi $t1 #load reminder in t1
beqz $t1,evenNumber
add $t0,$t0,2 #number is odd so adding two
j exit
evenNumber:
add $t0,$t0,1 #number is even so adding one
exit:

sw $t0,x #save value back to x

mips find bug.asm . data x : .word 2 check x and do even odd.asnm . text lw $t0 'x #load value of x div $t1,$t0, 2 #di vi de by two mfhǐ $t1 #load reminder in tl beqz $tl,evenNumbe r add $tO,$t0 , 2 #number is odd so adding two j exit evenNumber: add $t0, șt0,1 #number is even so adding one exit: sw $t0,x #save value back to x
