Field-Programmable Gate Arrays

A flexible FPGA logic module circuit includes a first logic circuit (12) for receiving a first plurality of input signals (14) and generating a first logic output signal (36) in response to the first plurality of input signals (14). A second logic circuit (24) for receiving a second plurality of FPGA logic modules (26, 28, 30, 54) for receiving a second plurality of input signals (44, 46, 48, 50, 52, 56, 64, and 66) and generating a second logic output signal (62) in response to the second plurality of input signals (44, 46, 48, 50, 52, 56, 64, and 66). Control circuitry (18) associates the first logic circuit (12) and the second logic circuit (24) to receive a wide plurality of input signals (14, and 44, 46, 48, 50, 52, 56, 64, and 66). The first logic circuit (12) receives certain first ones (14) of said wide plurality of input signals and the second logic circuit (24) receives certain second ones of the wide plurality of input signals (44, 46, 48, 50, 52, 56, 64, and 66). The control circuitry (18) further associates the first logic circuit (12) and the second logic circuit (24) to produce a single logic output (62) from the wide plurality of input signals (14, and 44, 46, 48, 50, 52, 56, 64, and 66).
