摘要

PROBLEM TO BE SOLVED: To construct a handshake sequencing circuit on an array of variable logic cells. SOLUTION: A gate G1 where a request from a request source X is sent as a request to an output destination Y is composed of the LUT Ms1 of a cell 1A, a gate G2 where acknowledge from the output destination Y is sent as a request to an output destination Z is composed of the LUT Me1 of the cell 1A, wire where acknowledge from the output destination Z is sent as acknowledge to the request source X is composed of the LUT Mn1 of the cell 1A, and a Muller-C element 11 where the request of an input source X and the acknowledge of the output destination Y are inputted and a signal for controlling the opening/closing of first and second gates is outputted is composed of the LUT Mw1 of the cell 1A and the LUT Me2 of a cell 1B.
