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.


Can you provide me xlat instruction in 8086 and assembly program language?

The XLAT instruction in the 8086 assembly language is used to translate a byte in the AL register using a lookup table pointed to by the BX register. The effective address of the lookup table is determined by the value in AL, which is used as an index to fetch the corresponding byte from the memory location pointed to by BX. Here's a simple example program: MOV BX, OFFSET lookup_table ; Load the address of the lookup table MOV AL, [some_index] ; Load the index into AL XLAT ; Translate AL using the lookup table ; AL now contains the translated value In this context, lookup_table would be an array of bytes, and some_index holds the index for the translation.


What is XLAT?

XLAT, or "translation," typically refers to a process in networking where addresses are converted from one format to another, often associated with techniques like Network Address Translation (NAT). In the context of computer science, it can also pertain to the translation of programming languages or data formats. Additionally, XLAT may be used in various fields to describe the conversion or adaptation of information from one context to another.
