ABSTRACT:
An operational circuit for performing an operation of an arbitrary number of input data pieces by using a DMA transfer according to a descriptor control and output results. The arbitrary number of input data pieces are divided into a plurality of pieces to perform an operation processing without performing the operation of the arbitrary number of input data pieces at a time. The operational circuit once stores an intermediate result for each of the divided operations in an external storage device, performs an operation processing read with an intermediate result in the next operation processing, and obtains a final result by repeating these operation processings. The operation is performed at a cyclic unit of processing corresponding to the number of address registers provided in the operational circuit.
