Write The Assembly Language Programming To Find The 2's Complement Fo

1.	Write The Assembly Language Programming To Find The 2's Complement For A String Of 100 Bytes.?
Answer» The following would be the code: 2000 CLD : Clears the direction flag 2001 MOV SI, 4000 H : In the SI the STORE ADDRESS is placed 2004 MOV DI, 5000 H : In the DI the destination address is put 2007 MOV CX, 0064 H : In the CX the number of bytes to be 2`s complemented are placed 200A LODSB : The data byte is give to AL and INC SI 200B NEGAL : AL of 2`s complement. 200D STOSB : Current AL value into DI and INC DI 200E LOOPNZ 200A H : The loop is maintained till CX becomes = 0. 2010 HLT : Stop. The following would be the code:

Answer»

The following would be the code:

2000 CLD : Clears the direction flag
2001 MOV SI, 4000 H : In the SI the STORE ADDRESS is placed
2004 MOV DI, 5000 H : In the DI the destination address is put
2007 MOV CX, 0064 H : In the CX the number of bytes to be 2`s complemented are placed
200A LODSB : The data byte is give to AL and INC SI
200B NEGAL : AL of 2`s complement.
200D STOSB : Current AL value into DI and INC DI
200E LOOPNZ 200A H : The loop is maintained till CX becomes = 0.
2010 HLT : Stop.

The following would be the code:
