Abstract:
A programmable logic integrated circuit device comprising:a plurality of regions of programmable logic disposed on the device in a two-dimensional array of intersecting rows and columns of said regions, each of said regions being programmable to perform any of a plurality of logic functions on a plurality of logic region input signals applied to the logic region to produce at least one logic region output signal; a plurality of interconnection conductors associated with each of the rows and configured to convey signals to, from, and/or between the logic regions in the associated row; and at least one programmable logic connector respectively associated with each of the interconnection conductors and configured to programmably select any of a plurality of PLC input signals applied to the programmable logic connector for application to the interconnection conductor associated with that programmable logic connector, at least one of the PLC input signals applied to each programmable logic connector being the logic region output signal of a logic region in the row associated with the interconnection conductor that the programmable logic connector applies a signal to, and at least one other of the PLC input signals applied to each programmable logic connector being the logic region output signal of a logic region in another row which is applied to the programmable logic connector substantially directly from the logic region in the other row.
