<p><P>PROBLEM TO BE SOLVED: To suppress useless processing and power consumption of a microcomputer. <P>SOLUTION: The microcomputer enters a sleep mode when a plurality of application tasks are executed and all the application tasks are not needed to be executed. When the microcomputer in the sleep mode wakes up by one of plural kinds of wake-up factors, a state management task wakes up, and the current wake-up factor this time is discriminated by the state management task (S310), and only the application task to wake up by the discriminated wake-up factor, is worken up (S320). The unnecessary increase of processing load is thereby prevented, and the following problem can be solved that unnecessary application tasks cannot be executed, so that a sleepable task cannot be determined quickly. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
