Question

Q2. Write and run following programs using 8086 assembly language:
(3 x 10 = 30)
(a) Write and run an Assembly language program that converts a packed 4 digit BCD number
that has been stored in two consecutive byte locations in the memory, into an equivalent
binary number. The output should be stored in DX register. For example, if two consecutive
byte locations have BCD values (12)n and (34)n then output will be binary equivalent of
(1234)10 which is (0000 0100 1101 0010)2. This binary value will be stored in DX register.​

Answer 1

Q2. Write and run following programs using 8086 assembly language:

(3 x 10 = 30)

(a) Write and run an Assembly language program that converts a packed 4 digit BCD number

that has been stored in two consecutive byte locations in the memory, into an equivalent

binary number. The output should be stored in DX register. For example, if two consecutive

byte locations have BCD values (12)n and (34)n then output will be binary equivalent of

(1234)10 which is (0000 0100 1101 0010)2. This binary value will be stored in DX register.
