摘要：
The invention provides a Configurable Logic Element (CLE) preferably included in each of an array of identical tiles. A CLE according to the invention has four function generators. The outputs of two function generators are combined with a fifth independent input in a five-input-function multiplexer or function generator to produce an output that can be any function of five inputs, or some functions of up to nine inputs. The outputs of the other two function generators are similarly combined. The outputs of the two five-input-function multiplexers or function generators are then combined with a sixth independent input in a six-input-function multiplexer or function generator. The six-input-function multiplexer or function generator therefore produces an output that can be any function of up to six inputs. Some functions of up to nineteen inputs can also be generated in a single CLE.
