Arithmetic processing unit

Abstract

An arithmetic processing unit that performs processing of a stream-type includes an arithmetic unit configured to operate an input operand to obtain a result of operation; and a data input and output unit configured to read the input operand out of a memory when an instruction which is issued in a case where a stream length of the input operand is shorter than a stream length of an output operand corresponding to the input operand and includes data indicating a recursive rule used when the input operand is read out, to supply the read input operand, and to store the result of the operation obtained by the arithmetic unit in the memory as the output operand, wherein the arithmetic unit 20 operates the input operand read out by the data input and output unit and outputs the result of operation to the data input and output unit.
