THREE INPUT FIELD PROGRAMMABLE GATE ARRAY LOGIC CIRCUIT CONFIGURABLE AS A THREE INPUT LOOK UP TABLE, A D-LATCH OR A D FLIP-FLOP

摘要

A field programmable gate array logic cell includes a logic circuit having three inputs and at least one output and a plurality of multiplexers having inputs and outputs. The logic circuit also includes a plurality of programmable elements coupled between the three inputs and at least one output of the logic circuit and the inputs and outputs of the plurality of multiplexers such that a plurality of sequential logic units and combinatorial units can be realized by programming selected ones of the programmable elements, the sequential logic units may include a flip-flop.
