嵌入式网络中代码移动性的研究

Study on code mobility in embedded networks

随着嵌入式应用领域的不断扩展,在越来越多的应用中要求实现嵌入式设备的网络化。网络化的需求对嵌入式系统软件的开发提出了新的要求。传统的嵌入式网络的编程方式效率低下、调试手段单一,已经难以满足快速开发、快速部署等现代嵌入式系统的开发要求。针对传统的嵌入式网络软件的开发方式,提出了将代码移动技术应用于嵌入式环境下的网络开发,实现了嵌入式的可编程网络;并针对嵌入式环境的特点提出了几种可能的实现手段,然后进行了比较。最后用实例说明了代码移动在车身控制系统开发中带来的益处。

Along with the extension of embedded application domains, there are more requirements to network the embedded devices. These requirements bring some new problems to embedded software development. The traditional embedded network programming method is inefficient and difficult in debugging. The traditional method is hard to satisfy modem requirements such as quick development and quick deployment. A method using code mobility in embedded network software development for solving above problems and implementing programmable network is proposed. Several technologies for implementing code mobility are introduced and compared. A code mobility application for vehicle control system is illustrated.
