IN SPARC ASSEMBLY ONLY write a program that prompts the user

IN SPARC ASSEMBLY ONLY, write a program that prompts the user for two numbers and prints the sum. THIS MUST BE IN SPARC ASSEMBLY. DO NOT WRITE IT IN NORMAL ASSEMBLY LANGUAGE.

Sample:

Enter Number 1:

2

Enter Number 2:

3

The sum of 2 and 3 is 5

Note:

-Your program should contain .data, .bss, and .text sections

-DO NOT try to optimize your code (i.e remove nops)

-DO NOT write this in regular assembly, it must be in SPARC

Solution

.model small

.stack 100h

.data

prompt db 13, 10, \'First number:\',\'$\'

prompt db 13,10, \'Second number:\', \'$\'

result db 13, 10, \'Sum\',\'$\'

;Variables

num1 db ?

num2 db ?

sum db ?

.code

main proc

    mov ax,@data           ;get data segment address

    mov ds,ax              ;initialize ds

;Display Prompt

    mov ah,9    ;print string function

    mov dx,offset prompt;ds:dx points to string

    int 21h

; Numbers from the user

    mov ah,1    ;input function

    int 21h

    mov bl,al   ;save the value from input

    mov num1,al

    mov ah,9

    lea dx, prompt ;print prompt

    int 21h

    mov ah,2    ;input second function

    int 21h

    mov bh,al   ;save the value from second input

    mov num2,al

;Addition

        mov ax,num1         ;move num1 into ax

        add ax,num2         ;add first and second numbers together

        mov sum,ax           ;move the total sum of numbers in sum

;Print Sum

    mov ah,9

        lea dx, result       ; print result

    int 21h

    mov ah,2

    mov dl,bl

    int 21h

        mov dl,\'+\'           ;display + sign

    int 21h

    mov dl,bh

    int 21h

        mov dl,\'=\'           ;display = sign

    int 21h

    mov dl,bh

    int 21h

        mov ah,4ch

        int 21h
