Question

This code needs to be written in Assembly language using Keil uvision 5. Please use Keil Assembler. Or ARM assembly.
Thanks.

int main(void) { // initializing int R0 = 5; int R1 = 10; // for loop addition with CMP while(RO <=| 10) R$++; // for loop subtraction without CMP#10 while(R1 > 0) R1--; // if else statement if (RO > 0) R0 = 10; R1 = 10; else | R0 = 20; R1 = 30; // must using branching (gotoCondition Instructions) instead of if- 11 else to write following statements R2 = RO; R3 = R1; if (R2 == 10) R2 = 5; R3 = 6; else R2 = 2; R3 = 3; return 0;

Answer 1

ASSEMBLY LANGUAGE PROGRAM FOR MULTIBYTE ADDITION

AIM: Write an assembly language program for multibyte addition using keil software (AT89C51).

APPARATUS: 1. Keil software

2. P.C.

PROGRAM:

MOV R0,#20H

MOV R1,#30H

MOV R3,#04H

CLR C

CLR A

AGAIN: MOV A,@R0

ADDC A,@R1

MOV @R1,A

INC R0

INC R1 DJNZ R3,

AGAIN

END

RESULT:

Inputs: i: 0x20 -- 01h, 02h, 03h, 04h

i: 0x30 -- 05h, 06h, 07h, 08h

Output: i: 0x30 -- 06h, 08h, 0Ah, 0Ch
