Write a program to add two 8 bit numbers in microprocessor 8086?

Answer 1

its munch, my program will add two 8-bit no. and store ina memory location

MVI 20H //copies 20h to accumulator

ADI 30H //adds 30h with the content of accumulator

STA 3000H //store result in 3000h lpcation

HLT //stop operation

this operation also can be done with taking the values from memory location as

LDA 2000H //loads accumulator with contents of 2000h location

MOV B,A //copies the content of accumulator to register B

LDA 2001H //loads acc with the content of 2001h

ADD B //adds acc with content of register B

STA 3000H //stores result in location 3000h

HLT //stops operation

and there are further many ways to perform the same dependent on many conditions such as carry etc.

Answer 2

Mov a,#08
mov b,#02
add a,b
mov dptr,#4500
movx @dptr,a
h1:sjmp h1

Answer 3

Lda 9000

mov b,a

lda 9001

mvi c,00

add b

jnc next

inr c

next : sta 9002

mov a,c

sta 9003

hlt

Answer 4

( bINARY EQV OP CODE)

MVI 20H ( 3E 20)

MVI 10H (06 10)

ADD B (80)

STA 2030 (32 30 20)

HLT (76)

Answer 5

Mvi a,80

mvi b,85

add b

hlt
