摘　　要：目前市场上的便携式视频展示台普遍功耗大、成本高。针对此问题,基于对ARM9和FPGA的嵌入式实时图像处理平台的研究,提出了一种便携式视频展示台的设计方案。充分利用ARM9高性能、低功耗、低成本等特点,结合FPGA传输处理高分辨率图像的能力,设计了便携式视频展示台,其具有体积小、易携带、低功耗、低成本和高清显示等特点。此外,详细介绍了各模块Linux设备驱动的设计。Currently, portable video showcases on the market usually have big energy consumption and high cost. To solve this problem, a new kind of portable video showcase based on ARM9 and FPGA embedded real-time image processing platform is put forward. ARM9 ＇ s high performance, low power consumption, low cost and other characteristics are taken full advantage in this scheme. As the ability of FPGA which can transport and process high-res- olution images is combined, the designed portable video showcase have some characteristics, such as small, easy to carry, low energy consumption, low cost, high definition display and so on. Additionally, the Linux device driver design of each module is discussed in detail.
