Abstract:
A variable circuit for changing a circuit configuration by changing connected states of a plurality of flipflops, wherein the plurality of flipflops are arranged in a first and a second rows, and in the case that the flipflops in the first and second rows are alternately arranged, an input side of each flipflop arranged in the first row has a connection selected from a twisted connection with an output side thereof, a straight connection with an output side of the flipflop provided before this flipflop in the first row, and twisted connections with output sides of two flipflops arranged in the second row and adjacent to this flipflop, and an input side of each flipflop arranged in the second row has a connection selected from a twisted connection with an output side thereof, a straight connection with an output side of the flipflop provided before this flipflop in the second row, and straight connections with output sides of two flipflops arranged in the first row and adjacent to this flipflop.
