Abstract

Programmable array logic circuitry is disclosed wherein the outputs from a field programmable AND gate array are connected, non-programmably, to specified OR gates. For greater architectural and operational flexibility, registered outputs, internal feedback to the AND gate array, input/output pin interchangeability, and means for allowing performance of arithmetical, as well as logic, operations, are provided.
