Question

Any help with this computer Organization and Architecture question
It's on assembly language procedure
Please use TASM

3. Write a procedure called divides that takes two parameters in BX and CX. Assume unsigned integers. It should print to the screen "EVENLY" if CX divides BX evenly. Otherwise, it should print "NOT EVENLY." DO NOT USE THE DIV OR IDIV COMMANDS. Use repeated subtraction to determine whether BX is divided evenly (no remainder.) Before printing clear entire screen with red background and blue text. Print in the top left corner of window. For example, if BX is 24 and CX is 8 24-8-8-8-0 you would print "Evenly" Another example if BX-27 and CX -5 27-5-5-5-5-5-2 you would print "Not Evenly" Push and pop registers on the stack as appropriate for your procedure. Show what would be in the data segment.

Answer 1

Please find the code below::

.model small

.stack 100h

.data

msg1 db 'Evenly$'

msg2 db 'Not Evenly$'

.code

main proc

mov ax,@data

mov ds, ax

mov cx,5 ;CX VALUE

mov bx,27 ;BX VALUE

push cx ;PUSH TO STACK

push bx

jmp divides ;CALL FUNCTION

return: ;FUNCTION RETURN

mov ax, 4c00h ;TERMINATE

int 21h

main endp   

;;;;;;FUCNTION STARTS

divides:

pop bx ;;get argument value from stack

pop cx   

loopHere:

sub bx,cx ;SUBTRACT BC FROM BX

cmp bx,0 ;CHECK IF RESULT ZERO,, THAN PRINT EVENLY

je evenly

cmp bx,cx ;IF NOT ZERO CHECK IF NUMBER IS LESS THAN BX, THAN PRINT NOT EVENLY

jl notEvenly

jmp loopHere ;LOOP CONTINUE

evenly:

mov dx, offset msg1   

mov ah, 9

int 21h

jmp return

notEvenly:

mov dx, offset msg2   

mov ah, 9

int 21h

jmp return

end main

;;;;;;FUCNTION ENDS

output:
