Patent ID: 8099540

Claim:
A reconfigurable circuit comprising: an arithmetic unit group including a first output terminal and a second output terminal, and performing arithmetic operations; a network circuit including a first input terminal, a second input terminal and a switch, and switching connections between output terminals and input terminals of said arithmetic unit group by the switch; and a first selector connected between said arithmetic unit group and the network circuit, wherein the output terminals of said arithmetic unit group are connected to input terminals of said first selector, output terminals of said first selector are connected to input terminals of said network circuit, and output terminals of said net work circuit are connected to the input terminals of said arithmetic unit group, and wherein when a first control signal is in a first state, said first selector connects said first output terminal of the arithmetic unit group to said first input terminal of the network circuit, and also connects said second output terminal of the arithmetic unit group to said second input terminal of the network circuit, while when the first control signal is in a second state, said first selector connects said first output terminal of the arithmetic unit group to said second input terminal of the network circuit, and also connects said second output terminal of the arithmetic unit group to said first input terminal of the network circuit.
