面向构件“即插即用”式复用的平台设计

Technology of Designing Platform Orienting Reusing Components Based on Plug and Play Mode

平台系统设计复杂度的持续增长,使构件互连结构的吞吐量、功耗、信号完整性、延迟以及时钟同步等问题日益复杂。针对构件间基于总线互连的通信架构的可扩展性和可复用性差等问题,引入基于分组交换网络的构件互连架构,该架构采用全局异步局部同步机制,采用可扩展的分组交换通信框架,支持构件"即插即用"式复用为基础的平台设计,同时解决了构件间互联的通信瓶颈问题。

System platform design encounters some problems, such as throughput, power, signal in- tegrity, latency and clock synchronization. As bus-based components communication architecture will not be able to serve future system, communication infrastructure based on network of compo- nents was introduced to solve the problems mentioned above. The architecture adopts globally asyn- chronous locally synchronous method, solving communication bottleneck of components on platform benefits from scalable packet switched communication infrastructure and component reused based on plug and play mode.
