基于以太网接口的多DSP监控技术研究

Research on Multi-DSP Monitoring Technology Based on Ethernet Interface

针对多DSP系统开发过程中不同DSP的调试工作难以并行进行的特点,设计了一种基于以太网接口的多DSP监控系统;该系统借用了网络编程中常用的"客户/服务器"模式,在系统底层实现一个"监控服务器",然后再通过网络将监控资源共享,从而使多人同时调试同一目标板上的不同DSP成为可能;文章重点阐述了其硬件结构和软件框架设计,并对软件设计关键部分的实现思路进行了分析;应用结果表明,该监控系统可以明显提高多DSP系统的开发效率。

Aiming at the difficuhy of debugging different DSPs in parallel when developing a muhi-DSP system, a multi-DSP monitoring system based on Ethernet interface is designed. Following the ＂client-server paradigm of interaction＂in network programming, a ＂mo- nitoring server＂ is implemented in the low-level system firstly, and then the monitoring resources are shared on the local network to make it possible to different developers to debug different DSPs on the same board simuhaneously. It especially introduces the design of the structure and frame of the system hardware and software. Furthermore, the implementing methods of the crucial parts of system software is discussed. The actual application of this system has markedly increased the developing efficiency of Multi-DSP systems.
