<p>PROBLEM TO BE SOLVED: To provide an arithmetic processing unit in which it is not necessary to perform interruption management by a CPU and a CPU load can be reduced.SOLUTION: An arithmetic calculation unit is constituted of a CPU unit 2 that performs arithmetic processing and an input/output controller unit 3 that exchanges input/output signals with an external input/output device, first to fourth input/output controllers 31 to 34 generate interruption signals to the CPU unit 2 by a fixed cycle, and first to fourth cores 21 to 24 for performing processing of input/putout signals of the first to fourth input/output controllers 31 to 34 corresponding to the interruption signals are predetermined.</p> |
