Abstract
A configurable logic circuit achieves versatility by including a configurable combinational logic element, a configurable storage circuit, and a configurable output select logic. The input signals to the configurable combinational logic element are input signals to the configurable logic circuit and feedback signals from the storage circuit. The storage circuit may be configured to operate as a D flip flop with or without set and reset inputs, an RS latch, a transparent latch with or without set and reset inputs, or as an edge detector. In conjunction with the combinational logic element, the storage circuit may also operate as a stage of a shift register or counter. The output select logic selects output signals from among the output signals of the combinational logic element and the storage circuit.
