<P>PROBLEM TO BE SOLVED: To provide a processing system capable of reducing a power consumption effectively by one processing device, by substituting for clocking necessary for a function of one processing device by another processing device. <P>SOLUTION: A power source management ECU (Electronic Control Unit) 1 which is one processing device determines necessity of clocking by a body ECU 2 which is a specific processing device capable of performing clocking processing always highly accurately (step S1), and when determined to be necessary (S1: YES), transmits clocking request together with a designated time to the body ECU 2 (step S3). The body ECU 2 which is the specific processing device receives the clocking request (step S6), starts clocking of the designated time (step S8), and when determined that the designated time has elapsed (S9: YES), transmits notification of elapse of the designated time to the power source management ECU 1 (step S10). <P>COPYRIGHT: (C)2011,JPO&INPIT |
