Different from the past work, this paper considers schedulability conditions for stochastic real-time tasks. A schedulability condition is first presented for frame-based stochastic real-time tasks, and several algorithms are also examined to check the schedulability of a given strategy. An approach is then proposed based on the schedulability condition to adapt a continuous-speed-based method to a discrete-speed system. The approach is able to stay as close as possible to the continuous-speed-based method, but still guaranteeing the schedulability. It is shown by simulations that the energy saving can be more than 20% for some system configurations. © 2008 IEEE.Frame-based systems; Schedulability conditions; Stochastic low-power real-time scheduling[SDGs]SDG7Discrete frequencies; Energy savings; Energy-efficient; Frame-based systems; International conferences; Real-time computing systems; Real-time task scheduling; Real-time tasks; Schedulability; Schedulability conditions; Stochastic low-power real-time scheduling; System configurations; Computer systems; Embedded systems; Energy conservation; Energy efficiency; Speed; Stochastic programming; Theorem proving; Real time systemsconference paper10.1109/RTCSA.2008.82-s2.0-53549133377https://doi.org/10.1109/RTCSA.2008.8
