RECONFIGURABLE ARITHMETIC DEVICE

PROBLEM TO BE SOLVED: To switch the circuit configuration of a plurality of reconfigurable arithmetic unit groups for each group in a reconfigurable arithmetic device. SOLUTION: The reconfigurable arithmetic device comprises: a plurality of reconfigurable arithmetic unit groups 34, 35 and 36 including at least one arithmetic unit; a reconfigurable bus network 5 which can use arbitrary output data of the arithmetic unit groups 34, 35 and 36 as arbitrary input data of the arithmetic unit groups 34, 35 and 36; a sequencer 31 for outputting address information and a switch timing signal for controlling the circuit configuration of the plurality of arithmetic unit groups 34, 35 and 36; and a circuit configuration outputting part 4 which can reconfigure the plurality of arithmetic unit groups 34, 35 and 36 for each group.
