SLEEP MANAGEMENT FOR RTOS ENVIRONMENT

原文（中文）

A system and method for managing sleep mode in a real time operating system is disclosed. The system utilizes certain ARM processors which incorporate a SLEEP ON EXIT feature. This feature allows the processing unit to enter sleep mode once the lowest priority exception handler has terminated operation. Additionally, the system utilizes thread mode, or user mode, without the use of an idle task. The functions typically performed by the idle task are now incorporated into various interrupt service routines and the PendSV exception handler. Further, the system supports two or more different sleep modes.
