嵌入式Email系统是类PC嵌入式系统,是嵌入式操作系统及其应用软件的一个重要组成部分,但是现有PC上的嵌入式Email系统都不能适应类PC嵌入式系统的硬件环境要求。文中采用了一种新的构建嵌入式Email系统的方法,设计与实现了清华嵌入式Email系统,可根据各种类PC嵌入式系统的不同要求进行定制。首先,论述了类PC嵌入式系统的硬件平台对嵌入式Email系统的苛刻要求,其次,描述了清华嵌入式Email系统的体系结构,接着,讨论了清华嵌入式Email系统的实现机制与原理,以及系统模型,最后,给出了嵌入式Email系统的特点。由于采用了现在流行的一种开放源码的组件,使得整个系统功能完善,并能够完全符合类PC嵌入式系统的要求。嵌入式Email系统已经在自主研制的掌上电脑HPC和交互式网络电视上成功地运行。
Embedded Email System is a kind of embedded system of PC, which is an important part of embedded operating system and its application software. However, the embedded Email system of existing PC can not meet the hardware environment requirements of the embedded system of PC. In this paper, a new method of constructing embedded Email system is adopted, and Tsinghua-based embedded Email system is designed and implemented, which can be customized according to different requirements of various types of embedded systems of PC. First of all, the hardware platform of PC-based embedded system is discussed. The system architecture of Tsinghua-based Email System is described. Secondly, the implementation mechanism and principle of Tsinghua-based Email System are discussed. System model, and finally, gives the characteristics of embedded Email system. Thanks to the now popular open source component, the entire system is fully functional and fully compliant with the requirements of a class-based PC embedded system. The embedded Email system has been successfully run on the independently developed Pocket PC HPC and Interactive Web TV.
