摘要： 当进行嵌入式应用开发时，需要利用宿主机开发环境中的多种工具，例如交叉编译器、远程调试器、命令解析器和实时资源浏览器。不同的主机端工具需要支持主机-目标机通信，并会产生许多不一致性，使得目标系统的设计变得相当复杂。该文提出了一种实现主机端工具与目标系统交互的通信机制，在自主嵌入式实时操作系统ReWorks中，设计开发了一个目标机代理。

Abstract: When developing embedded applications, cross-development environment needs to provide various kinds of host tools such as cross compiler, remote debugger, interactive shell, and real-time resource browser etc. The heavy host-target communication and inconsistency caused by tools make target agent more complex. This paper proposes a mechanism which establishes the communication line between several host-resident tools and embedded application, and develop a target agent running in the embedded real-time operating system——ReWorks.

Key words: Target agent, Remote debugger, Cross-development environment
