摘　　要：针对嵌入式系统开发平台中进程调度实时性差的问题,给出了一种提高进程调度实时性的设计方案。详细分析了嵌入式系统开发平台的进程状态及其转换过程,给出了进程调度思想,设计并实现了嵌入式系统开发平台核心层进程调度。通过引入就绪队列、设置进程调度变量等方式,改进了嵌入式系统开发平台进程调度的实时性。To improve the real-time process scheduling performance of embedded system developing platform, a new design approach is proposed. Based on detail analysis of process states and switch processes of the embedded system, the design principle of process scheduling is given, and the progress schedule of Embedded System Developing Platform Kernel Layer is designed and realized. Real-time performance of the progress schedule is effectively improved by implementing ready queue and variable of the progress schedule in the Embedded System Developing Platform.
