嵌入式系统仿真开发环境的体系结构

Software Bus Based Architecture of Embedded System Simulation Development Environment

对软件体系结构进行了研究,设计了iBus软总线,由总线核和总线适配器组成一个基础结构,作为通信通道连接系统功能部件。总线核嵌入系统主程序、动态创建总线适配器和挂接各个系统功能部件,实现了软件系统集成和即插即用。基于iBus体系结构,提出了一个可扩展和稳定的集成框架,可用于构造嵌入式系统仿真开发环境。

The development of embedded application is becoming more and more popular, and simulation development tool is a rapid, effective and low-cost tool for it. A software bus architecture named iBus has been researched and designed based on in-depth investigation of the use of Software Architecture. As a communication channel for the interconnection of system components, iBus is expected to be a firm infrastructure which is composed of bus core and bus adapter. The bus core embeds itself into main program, and then create bus adapters dynamically to connect system components. By this means, iBus can achieve system integration and the function of plug and play in software system. Based on iBus architecture, an integrated framework which is extensible and stable has been presented for efficient construction of the embedded system simulation development environment.
