【摘要】 高性能600MHz的TMS320DM642是可编程的数字多媒体处理器,为了了解其对于多媒体数据通信的支持,本文针对DSP芯片上的网络开发工具NDK进行了研究,测试了其在UDP传输过程中的CPU效率,对其在不同传输速率和二级缓存大小的条件下的表现给出了比较。说明了DM642是一款很适用于多媒体通信的数字信号处理器。更多还原

【Abstract】 600MHz TMS320DM642 is an excellent Digital Signal Processor. To support its function of multimedia data transmission, our work focuses on the Network Development Kids- NDK on it. We have a test on DM642 CPU’s efficiency of transmission of UDP data package; make comparison of the performance under different hardware conditions, including different transmission speed and different size of L2 cache. DM642 performs well in multimedia communications area.更多还原
