摘要：The present invention provides a parallel arithmetic apparatus capable of easilyperforming vector inner product operations as well as efficient matrix operations. Aparallel arithmetic apparatus (100a) is provided with pairs of registers (120a to 120d) thatrecord arithmetical elements to be operated and FMACs (140a to 140d) that performsum-of-products operations based on the arithmetical elements recorded in theseregisters (120a to 120d). Selectors (130a, 130b) are inserted between the register (120a)and the FMAC (140a). The selectors (130a, 130b) supply the arithmetical elementrecorded in the register (120a) to the FMAC (140a) during a matrix operation, select theregisters (120a to d) one by one in a round-robin fashion and supply the arithmeticalelement recorded in the selected register to the FMAC (140a) during a vector innerproduct operation.
