Q50 / 100
What is the function of a "PLA" (Programmable Logic Array) compared to a "PAL" (Programmable Array Logic)?
Correct! Well done.
Incorrect.
The correct answer is A) A PLA has both a programmable AND array and a programmable OR array, offering more flexibility, while a PAL has a programmable AND array but a fixed OR array, making it simpler and often faster but less flexible
A
Correct Answer
A PLA has both a programmable AND array and a programmable OR array, offering more flexibility, while a PAL has a programmable AND array but a fixed OR array, making it simpler and often faster but less flexible
Explanation
The trade-off between PLAs and PALs reflects flexibility versus simplicity/speed: PLAs allow more complex function implementations due to their dual programmable arrays, while PALs are simpler (and historically cheaper/faster) due to a fixed OR stage.
