Best Answer

XLAT introduces the concept of a "dictionary lookup." It is technically the same as "mov al,[ds:bx+al]", but with fewer bytes of instruction, and requiring fewer clock cycles. A developer might use this when determining which dynamic function to call based on some condition, or use it to look up the value of a byte in a certain memory area, or even when using it as a simple Ceasar cipher encoder/decoder (for elementary encryption of code, perhaps, as it'd be fairly useless for actual encryption).

What is the function of xchg and xlat in 8086?

xchg- Exchange contents of specified destination and source operands. eg. XCHG AL, CL Exchange contents of Al with CL XCHG BP, SI Exchange contents of BP with SI xlat- It is a translate instruction used for code conversion using look up table technique


What is xlat in 8086?

XLAT instruction converts the contents of AL register into a number stored in a memory table,this instruction perform the direct table look up technique often used to convert one code to another.An XLAT instruction 1st add the contents of this AL to BX to form a memory address within a data segment .It then copies the contents of this address into AL.This is the only instruction that adds an 8 bit number to 16-bit number.
