摘　　要：为了实现对高帧率、高分辨率图像的智能化实时处理,要求图像处理系统具有较高的数据传输带宽和数据处理能力。采用多核DSP作为核心处理器来解决目前图像采集平台面临的数据传输瓶颈和处理瓶颈,利用FPGA硬件化并行处理的特性完成多路视频的预处理,设计了高速串口Rapid Io通信接口实现视频的实时传输,对DSP的多核调度特性进行分析,保证处理的实时性,并采用相关算法验证系统的性能。In order to achieve intelligent real- time processing of the image with high frame rate or high resolution,the image processing system has been required to have higher data transmission bandwidth and data processing capacity. Multi- core DSP is used as the core processor to solve the data transmission and processing bottleneck which the current image acquisition platform facing. The characteristics of FPGA＇ s hardware parallel processing are made use of to complete the preprocessing of multi- channel vedio. The communication interface of high- speed serial Rapid Io is designed to realize real- time transmission of the video. The multi- core scheduling characteristics carry on being analysed to ensure the real- time processing,and test the system＇s performance based on related algorithm.
