Abstract
A logic module 400 for use in a field programmable gate array 100 can be selectively reconfigured to perform over 2,200 boolean combinational functions on output 431, to operate as a full adder with sum and carry outputs, or to perform the sequential function of a D latch or a D flipflop. Logic module 400 is comprised of 2-input multiplexers 500 and 600 which are used to form both the combinational and sequential circuits, thereby efficiently utilizing space on gate array 100.
