Abstract:
A programmable logic integrated circuit device comprising:a plurality of regions of programmable logic arranged 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 said logic region to produce at least one logic region output signal; a plurality of interconnection conductors associated with each row of logic regions, each interconnection conductor constructed to convey said signals to, from, and/or between said logic regions in the associated row; a plurality of interleaved vertical conductors associated with adjacent rows of said logic regions, each interleaved vertical conductor constructed to convey a respective logic region output signal between the adjacent rows of said logic regions; and at least one programmable logic connector respectively associated with each interconnection conductor, said at least one programmable logic connector operative to apply any of a plurality of PLC input signals being applied to said programmable logic connector for application to said associated interconnection conductor, at least one of the PLC input signals being a logic region output signal that is substantially directly conveyed by one of said interleaved vertical conductors from a logic region in a first row that is adjacent to the row associated with said interconnection conductor that said programmable logic connector applies a signal to.
