摘要
为解决嵌入式系统中应用业务的跨平台问题,设计了通用嵌入式系统服务平台(GSSP)。GSSP可运行在Vxworks,Windows,Linux等多种操作系统上,为应用业务开发提供服务接口。研究GSSP二级调度体系的原理,对二级调度数学模型进行理论分析,在GSSP中采用反馈权值进行调度,并对二级调度体系的实现方法进行描述,给出测试结果及结论。
In order to solve the problem of application porting on different platform in real-time embedded system, this paper designs a General Embedded System Service Platform（GSSP）, which can run on different operating systems such as Vxworks, Windows, Linux. It centers on the two-level scheduling system of GSSP, carries on study in the two-level scheduling system, analyzes model and proposes feedback weight schedule method. It provides realization method and the conclusion of GSSP performance according to the tests.
