一种跨平台敏捷式动态可重构系统架构研究

Research on Cross-platform Agile Dynamic Reconfigurable System Architecture

嵌入式系统的发展趋势是开放式跨平台,敏捷式重构,分布式协同,系统资源自适应适配等,而当前嵌入式系统架构解决方案普遍存在着功能相对固化,系统业务流程难以灵活重构,缺乏对多类型平台的适应能力等问题,无法匹配日益复杂的系统需求变化。因此本文提出了一种跨平台敏捷式动态可重构系统架构,该架构能够屏蔽硬件平台差异,提供高效的数据通信机制,具备硬件感知和组件动态重构能力,以及模块化图形化的系统配置能力。本文深入讨论了该架构的工作原理和关键技术,并在Power PC,ARM,DSP等多种嵌入式处理平台上进行了工程应用验证。

The trend of the embedded system is open cross-platform, agile reconstruction, distributed collabo- ration, system resource adaptive adaptation. However, the software architecture in embedded system usually with fixed functionality, lack of flexibility of processing, lack of adaptability to different type of platforms. It is difficult to match the increasingly changing of complex system requirements. Therefore, this paper proposes a cross-platform agile dynamic reconfigurable software architecture that shields the hardware platform differences and provides efficient data communication mechanisms with hardware awareness and component dynamic reconfiguration capabilities, as well as modular graphical system configuration capabilities. This paper discus- ses the principle and key technologies of this architecture in depth. Architecture already used and verified on a variety of embedded processing platforms such as PowerPC, ARM, DSP devices.
