基于TMS320C6000 DSP的FIFO—网络数据传输

Signal Transmitting through FIFO and Network on TMS320C6000 DSPs

随着网络技术的飞速发展,越来越多的嵌入式信号采集系统通过以太网来传输数据。而FIFO作为高速信号处理系统中常用的数据通道,也大量的用于嵌入式系统中。本文实现了一个基于TMS320C6000系列DSP的嵌入式信号处理——网络传输方案,在采集A/D数据并进行高速信号处理的同时,还通过FIFO以及DSP的网络接口,实现了高速的嵌入式数据通路,最终将结果传入计算机进行保存、显示和处理。文中给出了硬件框图和软件流程。同时针对在系统开发过程中遇到的一些问题,进行了较详细的分析讨论,提出了解决办法。

With the development of networking technology, more and more embedded signal processing systems use network interface to transmit data. At the same time, FIFOs, e.g. first in first out, are wildly used in embedded systems. An embedded signal processing -network transmitting project based on TMS320C6000 DSPs has been proposed, which realized massive A/D signal processing and data transmitting through FIFO and network, including hardware connecting means of plot of pane and software flowchart. Some related problems in developing the system have also been discussed, whose solutions have been put forward, too.
