Convert Java program to MIPS

What is the address that has been used by the simulator for this array?

Make sure it works on MIPS

Answer 1

Greetings!!

Code:

Assuming that the last 0 in the array indicate the end of the array.

#DATA SEGMENT

.data

A: .word 11,12,-10,13,9,12,14,15,-20,0

max_message: .asciiz "The maximum is "

sum_message: .asciiz "\nThe sum is "

#CODE SEGMENT

.text

#MAIN STARTS HERE

main:

la $a0,A            #load address of A

#CALLING TO FUNCTION MAX

jal Max

move $t0,$v0    #return from Max and copy the answer to t0

la $a0,max_message #load the address of the message

li $v0,4              #parameter for string display

syscall               #system call for string display

add $a0,$0,$t0   #copy the Max value to a0 for display

li $v0,1              #parameter for display integer

syscall               #system call for display integer

la $a0,A            #load address of A

#CALLING TO FUNCTION SUM

jal Sum

move $t0,$v0    #return from Sum and save the sum to t0

la $a0,sum_message   #load the address of the message

li $v0,4              #parameter for display string

syscall               #system call for display string

add $a0,$0,$t0   #load the value of sum to a0 for display

li $v0,1              #parameter for display integer

syscall               #system call for display integer

li $v0,10            #parameter for standard termination

syscall               #system call for termination

#MAX FUNCTION DEFINITION

Max:

lw $t0,0($a0)     #load the first number and assume that is max

move $t1,$t0     #copy to t1

loopm:

beq $t1,$0,endm #if the end of the array then goto label endm

addi $a0,$a0,4   #increment array index

lw $t1,0($a0)     #load the next number

bgt $t0,$t1,loopm       #if the new number is greater than old number

add $t0,$0,$t1   #else set the new number as max

j loopm              #repeat

endm:

add $v0,$0,$t0   #load the max number to v0 for return to main

jr $ra                 #return to main

#MAX FUNCTION END

#SUM FUNCTION DEFINITION

Sum:

lw $t0,0($a0)     #load the first number

move $t1,$t0     #copy to t1

loops:

beq $t1,$0,ends #if end of the array then ends

addi $a0,$a0,4   #else increment the array index

lw $t1,0($a0)     #read the next number

add $t0,$t0,$t1 #calculate the sum

j loops               #repeat

ends:

add $v0,$0,$t0   #load the sum to v0 for return to main

jr $ra                 #return to main

#FUNCTION SUM END

Hope this helps
