计算机外设的主机侧软件设计模式

Design Patterns of softwares on Host Side for Computer Peripherals

大量的计算机外设,将设备控制、数据分析和显示的功能留给了主机侧的软件来实现。本文针对如何使此类软件有更高的可维护性以适应软硬件的持续升级,总结了笔者的开发经验,提出了主机侧软件的设计模式。文章依次阐述了此设计模式的问题、解决方案和结果,给出了软件的静态结构和应用场景,并分析了各部分的要点和内部工作机制。

Lots of computer peripherals implement the function of equipment control,data analysis and display on host side software.This paper focus on how to make such kind of software have higher maintainability to adapt the continuous upgrading of hardware and software by summarizing the author＇s development experience.Finally it puts forward the design pattern on host side software.The article details the the problem,solution and consequence of this design pattern,and gives out a software static structure and application scenarios,also including the analysis of key points and internal mechanisms.
