Design and Implementation of Real-time Video Processing and Transferring System Based on TMS320C6678
Abstract— In order to resolve the problem that processing and transferring video in real time, using the TI TMS320C6678 high-performance multi-core DSP and its high-speed SRIO and PCIE interfaces, a real-time video processing and transferring system is designed and realized. Firstly, the hardware design of a video processing board is designed. Introduce the video capturing, pre-processing and how to process video in real time. And then introduce the data processing, data transferring via SRIO between chips and data transferring between board and host computer via PCIe. Especially introduce the realizing step and key points. Lastly, experiments using the designed board are implemented. The result shows that the transfer delay between FPGA and DSP is less than 240ns, which can meet the real-time quality of video processing system. The designed board can process and transfer video in real time and robustly.
