Explain Programmable Logic Devices and Programmable Logic Arrays with block diagrams?

A: It is a counter basically that increases it count by one. This counter output is the addresses for the chip to be programmed with information one a the time until the end.

Programmable array logic is used for designing the digital circuits easily.for example large function which has several variable can easily implemented by using programmable array logic.These are the...

drawback of programmable array logic Rapid prototyping of digital circuits and perhaps for smaller scale production.

used as mux and demux , used for implement haff adder $ full adder, by program it

Using and gate - pla is programmable while pal is fixed
