Question:
The instruction XLAT in 8086 microprocessor is used to
The instruction XLAT in 8086 microprocessor is used to
Show Hint
Remember the function of instruction set, and always remember XLAT translates a byte using the value in AL register, and storing the result in AL register.
Updated On: Feb 27, 2025
- Translate a byte in AL using a table index
- Transfer data from source to destination
- Push the contents of specified source on to the stack
- Exchange the contents of source with destination

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The XLAT (translate) instruction in the 8086 microprocessor is used for table lookups. It translates a byte from a lookup table in memory, using the AL register as a index. The translated value is stored back into AL. This instruction is used for tasks such as character mapping or code conversions.
