基于FPGA+DSP的高速视频实时处理系统设计

Design of a High-speed Real-time Video Processing System Based on FPGA and DSP

设计了一种基于FPGA+DSP的高性能视频实时处理系统,采用Xilinx公司的K7系列FPGA芯片作为核心控制器,采用TI公司TMS320C6455作为图形处理器。通过Camera Link总线接收高速视频数据,并将视频数据缓存在由4片DDR3-SDRAM构造64位宽的外部动态存储器内,同时根据接收视频的帧位置向DSP发送中断,DSP根据中断信息通过DMA的方式从DDR3中读取视频数据进行实时处理。试验结果表明,系统能够稳定实现分辨率1280×1024、位宽8bit、帧频520FPS的视频实时跟踪处理算法。

A high performance video real-time processing system based on FPGA and DSP is designed.K7 series FPGA chip of Xilinx company is used as the core controller,and TMS320C6455 of TI company is used as the graphics processor.The high-speed video data is received through Camera Link Bus,and the video is cached in the 64-bit wide external dynamic memory constructed by 4 pieces of DDR3-SDRAM.At the same time,according to the frame position of the received video,the interrupt is sent to DSP,and the DSP reads the video data from DDR3 for real-time processing by means of DMA.The experimental results show that the system can stably realize the real-time video tracking algorithm with 1280×1024 resolution,8bit width and 520fps frame rate.
