Abstract:
A field programmable gate array comprising:a plurality of configurable logic blocks (CLBs); a plurality of interconnects; a plurality of interconnect switches capable of coupling ones of said plurality of interconnects to each other and to inputs and outputs of said plurality of configurable logic blocks; and an interconnect switch controller capable of controlling said plurality of interconnect switches, wherein said interconnect switch controller in a first switch configuration causes a first interconnect to be coupled to an output of a first CLB, causes a second interconnect to be coupled to an output of a second CLB, causes said first and second interconnects to be coupled to a third interconnect, and causes said third interconnect to be coupled to a pull-up device coupled to a power supply source of said field programmable gate array, said first, second and third interconnects and said pull-up device thereby forming a two-input NOR gate.
