Programmable logic array integrated circuit devices with regions of enhanced interconnectivity

摘要

A programmable logic array integrated circuit device which includes a plurality of regions of programmable logic and interconnection resources for selectively conveying logic signals between various ones of said regions has at least one portion of its interconnection resources enhanced or augmented relative to other similar portions. Any portions of a user's logic that requires more than a usual amount of interconnectivity can be placed in the portion of the device which has the augmented interconnection resources. Examples of augmented interconnection resources are extra conductors for conveying logic signals along one or more rows and/or one or more columns of logic regions on the device.
