<P>PROBLEM TO BE SOLVED: To provide an information processing system which causes a slave processor (hereinafter referred to as SP) operate based on execution priorities of a task in a master processor (hereinafter referred to as MP) and can contribute in suppression of a device scale and device cost of an embedded system. Ž<P>SOLUTION: Communication data including a processing request for the SP21 from a request source task to be executed by the MP11 is transmitted to the SP21. The communication data includes priority information associated with execution priority in the MP11 of the request source task. The SP21 activates a communication processing task in response to reception of the communication data. The communication processing task is activated in common in response to reception of multiple pieces of communication data from multiple request source tasks. The communication processing task creates child tasks for executing processing requested by the processing request with execution priorities allocated corresponding to the execution priorities of the request source tasks. The SP21 executes the child task in accordance with task scheduling based on execution priority of each task. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
