PROGRAMMABLE LOGIC ARRAY Meaning and Definition

  1. A programmable logic array (PLA) refers to a digital electronic device that is designed to perform logical operations and store digital information. It is a type of programmable logic device (PLD) that offers configurable logic functionality to implement various digital circuits and systems.

    A PLA typically consists of an array of AND gates followed by an array of OR gates. The inputs to the AND gates are programmable through use of a set of input lines called product terms. The outputs of the AND gates are then fed into the OR gates, whose outputs determine the final logic outputs of the PLA.

    The beauty of a PLA lies in its programmability, which allows designers to customize the logic functions it implements. By configuring the product terms and OR gate outputs, complex logic circuits and functions can be implemented using a PLA. This flexibility makes PLAs an excellent choice for prototyping and testing digital circuits, as they can be easily reprogrammed as required.

    PLAs are commonly used in fields like digital design, computer architecture, and electronic circuit design. Their applications include implementing combinational logic circuits, such as arithmetic circuits or data flow control, as well as smaller-scale logic functions like multiplexers and demultiplexers.

    In summary, a programmable logic array is a versatile digital device that can be programmed to perform various logic functions by configuring its input and output connections. It serves as a fundamental building block in the development of digital circuits and systems.
