Claim:
1. A structure of a multi-mode supported and configurable six-input look-up table (LUT), wherein the six-input LUT has six signal input ends and two signal output ends; and the structure of the six-input LUT comprises: a first five-input LUT, a second five-input LUT, a first multiplexer and a second multiplexer, wherein the first five-input LUT receives five data signals input by five signal input ends of the six-input LUT, and outputs a first output signal according to the five data signals, wherein the first output signal is output by a first signal output end of the six-input LUT; the second five-input LUT receives five data signals input by the five signal input ends of the six-input LUT and outputs a second output signal according to the five data signals; and the first multiplexer outputs a control signal according to a set configuration mode, to control the second multiplexer to output the first output signal or the second output signal in a multiplexed manner, wherein the first output signal or the second output signal that is output by the second multiplexer in a multiplexed manner is output by a second signal output end of the six-input LUT.
