摘　　要：本文对在FPGA中嵌入Powerpc(hard IP Core),引入linux嵌入式操作系统用来开发嵌入式系统进行了研究,系统实现了高速数据采集、高速视频数据压缩、实时视频数据的网络传输和实时压缩图像数据存储功能,该方法采用linux嵌入式操作系统加FPGA中嵌入的Powerpc硬核处理器进行系统控制层面的处理,还根据FPGA的特点将视频处理等功能用高速硬件实时处理。系统适合于系统空间要求小且视频数据处理量大的应用。The article refers to study on developing embedded system based on FPGA embed Powerpc（hard IP Core）and linux embed ded operating system. The system achieves to functions of the high -speed data collection, the high -speed video data compression the real time video data Network Transmission and the real time compression picture data storage. The scheme introduce linux em bedded operating system and FPGA embedded Powerpc to be processing in control scopes and utilize high -speed hardware to rea time process video data based on FPGA trait, which can be suitably used for the system calling for both small system space and pocessing a mass of video data.
