STSF scalable task scheduling frame: Scalable task scheduling mechanism makes up the faulty of RTEMS which only use one scheduling algorithm-RM algorithm. And an improved RM algorithm which uses double-PRI strategy is implemented.

• 可扩展的任务调度框架--STSF(Scalable Task Schedule Frame):本文设计的可扩展的多处理器任务调度框架弥补了RTEMS只采用一种调度算法--RM调度算法带来的局限性,并实现了更高性能的基于双优先级策略的RM调度算法。
