中文摘要：
提出并设计了一种基于DSP芯片TMS320DM642的手图像实时显示和嵌入式网络实现方案,介绍了各模块的硬件实施方案和软件配置方式.图像数据由DM642处理后通过视频接口输出,由编码芯片转换为NTSC格式的模拟信号,并在显示屏上实时显示;系统利用DM642的EMAC将图像数据传输至物理层芯片实现物理层功能;通过RJ-45接口,完成了DSP与PC之间高速网络数据传输.
英文摘要：
An implementation plan of network for embedded system and real-time display for palm image is designed and proposed based on TMS320DM642.The hardware implementation plan for modules and configurations for software are introduced. Image data is output through video interface after processing in DM642.And then it is transformed into NTSC by coder chips. At last, it is real- timely displayed on the screen. Image data is transferred to the physical layer by using EMAC of DM642.In this way, the function of the physical layer is realized. High speed network data transmission is done between DSP and PC by the RJ-45 interface.
