基于DSP数字多功能板的实现

Research and implementation of digital multi-function board based on DSP

实现基于了DSP的数字多功能板。该功能板以数字信号处理技术为核心,提供多种对外接口。通过不同的DSP算法和微控制器程序,可处理交换机所需的各种信号,并完成音板的单板功能。结合项目实际分析该多功能板的结构和工作原理、软硬件接口、硬件组成及具体实现等。改进了目前基于DSP开发板只有一个单DSP的不足,而且便于维护和升级。

The paper intorduces the implementation of digital multi-function board based on DSP.The board uses digital signal processing as the core, provides many kinds of interface.Through different DSP algorithms and the microcontroller unit program,the board processes many signals which the switchboard needs,and completes the tone function.The structure and working principle, interface of software and hardware,hardware component and implemtntaiton of the multi- function board are analyzed.The mutli-funation board that only has a single DSP is improved,and is easy to maintain and upgrade.
