PROBLEM TO BE SOLVED: To provide a processor system which appropriately executes processing on one or a plurality of dedicated signal processing processors side according to a dynamic call from a plurality of processes on one or a plurality of general-purpose processors side, returns the result thereof appropriately to a calling source, and minimizes variation in processing performance as much as possible. SOLUTION: The processor system includes the dedicated signal processing processor (130), which is equipped with a means for caching sufficient amounts of both instructions and data in a program executed therein; and a means for transferring, to the one or the plurality of dedicated signal processing processors (130), a dynamic call from a plurality of processes in the one or the plurality of general-purpose processors (110) by issuing an interrupt signal and transferring command data using shared memories (151, 161), or the like; and a means for arbitrarily and dynamically executing or completing loading of a task on receiving a request from the general-purpose processor (110), in the dedicated signal processing processor (130).
