摘要
为了提升多核系统核间交互实时性和并行性,设计和实现了一种多核系统核间交互通信框架,在该框架下,设计专用的核间交互通道,核间交互时每个核使用独立的交互通道,避免核间互斥操作,从而提高并行性;设计核间交互数据结构,保证数据消息可扩展、适应性强、交互消息的原子性;提供核间交互同步模式,保证消息传递的可靠性和实时性,在嵌入式操作系统和硬件平台上实现并验证该方法。
In order to improve the real time and parallelism of inter nuclear interaction in multi core systems,a framework for inter nuclear interaction communication is designed and implemented.Under this framework,a dedicated inter nuclear interaction channel is designed.Each kernel uses an independent interaction channel during inter nuclear interaction to avoid mutually exclusive operations and thus improve the parallelism.The inter core interaction data structure is designed to ensure the extensibility,adaptability and atomicity of data messages.The method is implemented and verified on embedded operating system and hardware platform to ensure the reliability and real time of message transmission.
