摘要： 传统数字信号处理器(DSP)目标板通过总线调用硬件驱动层命令实现与DSP的通信,然而该方式需要考虑应用环境变化、服务程序中断等因素,会影响DSP应用开发效率,增加开发成本。为此,在对象请求代理(ORB)架构的基础上,对CORBA/e规范进行裁剪修改形成轻量级ORB规范。根据该轻量级规范编写框架代码和桩代码,并完成框架和适配器、公共数据、编解码等的轻量化设计。测试结果表明,该轻量级ORB能够较好地实现DSP的跨平台、跨系统互通,具有较高的通信效率。

Abstract: The traditional Digital Signal Processor(DSP) target board realizes communication with DSP through calling hardware driver lay commands by the bus.However,for this way,the application environment change,service program interruption and many other factors need to be considered,which seriously affects the efficiency of DSP and increases the development costs.Aiming at these problems,on the basis of Object Request Broker(ORB) architecture,this paper cuts and modifies the CORBA/e specification to form lightweight ORB specification.It writes the framework code and stub code on the basis of this lightweight specification and realizes lightweight design of framework,adapter,public data,encoder and decoder.Test result shows that the lightweight ORB can realize cross-platform and across-system communication of DSP,and it has higher communication efficiency.
