BINARY TO ASCII

BINARY TO ASCII

AIM:

To write an assembly language program for the code conversion of BINARY to ASCII.

APPARATUS REQUIRED:

                                    8085 kit, power chord

ALGORITHM:

1.      Start the program.

2.      Load the given data to A register and move to B register.

3.      Mask the upper nibble of the binary data in accumulator.

4.      Call sub routine code to get ASCII code of the lower nibble and store in memory.

5.      Move B register to accumulator and mask the lower nibble.

6.      Rotate the upper nibble.

7.      Call the subroutine to get the ASCII code of upper nibble and store in memory.

8.      Stop the program.

PROGRAM:   

Address	Label	Opcode	Mnemonics	Operand	Comments
4300		3A, 00,42	LDA	4200H	Load the input binary data in accumulator
4303		47	MOV	B, A	Move the data to B register
4304		E6, 0F	ANI	0FH	Masking the upper nibble
4306		CD, 1A, 43	CALL	CODE	Call the subroutine
4309		32,01,42	STA	4201H	Store the result
430C		78	MOV	A, B	Move the content of B register to accumulator
430D		E6, F0	ANI	F0H	Masking the lower nibble
430F		07	RLC		Rotating the content for 4 times
4310		07	RLC
4311		07	RLC
4312		07	RLC
4313		CD, 1A, 43	CALL	CODE	Call the subroutine
4316		32,02,42	STA	4202H	Store the result
4319		76	HLT		Stop the process
431A	CODE	FE, 0A	CPI	0AH	Compare the acc content with 0AH
431C		DA, 21,43	JC	SKIP	Check for carry, if carry present go to 4321 else go to 431F
431F		C6, 07	ADI	07H	Add the acc content and 07H
4321	SKIP	C6, 30	ADI	30H	Add the acc content and 30H
4323		C9	RET		Return to main prgm

INPUT:                                                          OUTPUT:

4200-E4                                                           4201-34

  4202-45

RESULT:

            Thus the assembly language program for Binary to ASCII Code conversion is executed and the results are verified.
