Answer to Question #165177 in Electrical Engineering for Fawad

Question

Suppose you had reduced a 32-variable Boolean expression using Quine–McCluskey algorithm to a 12-variable expression. For the generated simplified expression, you are required to implement it into a digital logic circuit. You can only use Programmable Array Logic (PAL) or Programmable Logic Array (PLA) devices.

Assume that we had selected a Programmable Array Logic (PAL) and a Programmable Logic Array (PLA) for you to choose between.

1.                   Using TICPAL22V10Z-25C (Programmable Array Logic)

2.                   Using PLUS173–10 (Programmable Logic Array).

Your selections among stated PLA and PAL must consider the following constraints:

•                     Complexity

•                     Flexibility

•                     Speed

•                     Functionality

•                     Cost

Answer 1

According to the given data we use programmable logic array (PLA) in this array of AND and OR gates it is less prolific and provides more programming flexibility as PAL and the large number of functions can be implemented.
