摘要
随着嵌入式系统新应用业务不断涌现,应用业务的跨平台移植问题日益突出。为解决应用业务跨平台开发的问题,有必要设计通用嵌入式系统服务平台(GSSP)。GSSP具有商用嵌入式系统的服务接口,可架构在多种操作系统之上,为应用业务开发提供服务。本文讨论了GSSP中二级调度体系的结构和原理,提出了一种基于市场机制的二级调度算法,并设计了二级调度模型的测试方法并对其性能进行了测试。
Along with the embedded real time system application being widespread, the new application service unceasingly wells up day by day. The problem of application service porting on different platform is prominent .In order to solve the problem. It is necessary to design a set of general embedded system service platform （GSSP）. GSSP supplies interface of commercial embedded system＇ s service. It can run over different operation systems. The paper centers on the two-level schedule system of GSSP, study have been carried on the theory of two-level schedule system, the MAMS model is proposed. The paper also provides realization method of the two-level schedule system and the conclusion of GSSP performance from test,
