PROBLEM TO BE SOLVED: To provide a stream processor suitable for real time control. SOLUTION: A stream processor includes a programmable main processor MP, and a co-processor CP that executes an extension instruction which is different from a basic instruction executed by the main processor MP. The main processor MP includes a co-processor controller CPC outputting the extension instruction to the co-processor CP, and the co-processor CP includes a task controller TC, the task controller controlling a task performed based on the extension instruction and outputting the status information ST of the task on every clock. The co-processor controller CPC controls the co-processor CP based on the status information ST and a basic instruction executed by the main processor MP in the background in advance.
