摘　　要：针对嵌入式多线程系统的不足,提出套任务分配、线程分割和任务调度的优化方法。为不同处理器分配系统任务,对线程进行分割,得到不同的系统通道数目后根据上述结果进行调度。实验结果证明,该方法能有效提升处理器的运行效率,同时减少系统开销,具有一定意义。Aiming at the deficiencies of embedded multi-threaded systems,a set of optimization methods for task allocation,thread segmentation and task scheduling are proposed.Allocate system tasks to different processors,divide threads,and schedule different system channels based on the above results.The experimental results prove that this method can effectively improve the operating efficiency of the processor while reducing system overhead,which is of certain significance.

关 键 词：任务分配 线程分割 调度 系统开销
