Changes

PLAs offered more greater flexibility than PALs but were less common in 8-bit computer designs due to their higher cost and power consumption. They featured programmable AND and OR arrays, which allowed for the implementation of more complex logic functions in a single device.

Distinguishing features:* Both AND and OR arrays Despite their limited use, PLAs were programmable* Could implement more sometimes chosen for advanced 8-bit systems, particularly for tasks like instruction decoding. A notable example is the Commodore 64, which used a PLA for part of its chip select and memory mapping logic. This illustrated the PLA’s ability to manage complex logic functions in a single deviceefficiently.

Applications:* While less commonnot as widely adopted, PLAs were sometimes used highlighted the need for flexibility in more complex 8-bit computer designs for tasks like instruction decodingdesign.* Example: The Commodore 64 used a PLA for part of its chip select and memory mapping logicThey were valuable in specific applications where intricate functionality was required, demonstrating showing their importance in the device's ability to handle development of certain complex logic in a single chip8-bit systems.
