Abstract
A programmable logic array integrated circuit has a plurality of programmable logic elements grouped into a plurality of mutually exclusive groups. Each group includes signal conductors uniquely associated with that group for conveying signals between the programmable logic elements in that group. Other signal conductors are provided for conveying signals between the groups. Multiplexers can be used in various ways to reduce the number of programmable interconnections required between signal conductors.
