Programmable Logic Arrays
Programmable logic arrays (PLAs) are traditional digital electronic devices.
A PLA is a simple programmable logic device (SPLD) used to implement
combinational logic circuits. A PLA has a set of programmable AND gates, which
link to a set of programmable OR gates to produce an output. The AND-OR layout
of a PLA allows for implementing logic functions that are in a sum-of-products
form. PLAs are available in the market in different types. PLAs could be stand
alone chips, or parts of bigger processing systems. Stand alone PLAs are
available as mask programmable (MPLAs) and field programmable (FPLAs) devices.
The attractions of PLAs that brought them to mainstream engineers include their
simplicity, relatively small circuit area, predictable propagation delay, and
ease of development. The powerful-but-simple property brought PLAs to rapid
prototyping, synthesis, design optimization techniques, embedded systems,
traditional computer systems, hybrid high-performance computing systems, etc.
Indeed, there has been renewable interests in working with the simple AND-to-OR
PLAs.Comment: 19 pages, 18 figures. arXiv admin note: text overlap with
