Adaptive low power design based on Vxworks kernel scheduler and hook machanism

Embedded system is always power-sensitive for its time-limited power-providing system. As a popular real time operating system used under embedded system, Vxworks provides a feasible way to achieve low power dissipation with its kernel scheduler and hook mechanism. This paper firstly gived the principle and implemention of the Low-power design under Vxworks, and then verified the feasibility of the design with the test result under a platform. The design methodolodgy introduced in this paper can maximize the power efficiency under embedded system and can be used as a reference for low-power design-related occasions under Vxworks.
