Define the concept of Programmable Logic Devices.

Programmable Logic Devices are integrated circuits that can be programmed to perform specific logic functions.

What is the purpose of a Truth Table in a Programmable Read Only Memory (PROM)?

The purpose of a Truth Table in a PROM is to define the output values for each input combination.

Explain the difference between a Programmable Read Only Memory (PROM) and a Programmable Logic Array (PLA).

A PROM is a combinational circuit with fixed AND and programmable OR gates, while a PLA is a combinational circuit with programmable AND and OR gates.

What is the advantage of using a Programmable Logic Array (PLA) over a PROM?

<p>The advantage of using a PLA over a PROM is that it allows for reduction in the number of AND gates, as the product terms can be shared by multiple outputs.</p> Signup and view all the answers

What is the programming overhead associated with a Programmable Logic Array (PLA)?
