Design of On-Line Detected Multi-channel Video Signal Processing System

In order to achieve high real-time in online detection processing, a multi-channel video signal processing system consist of FPGA and DSP is proposed in this paper. In the system, FPGA as the main controller completes all control functions, DSP as the co-processor, focuses on the algorithm of a large number of data. The paper mainly analyzes the principle of the system, studies its hardware structure, describes the function of each part how to realize in detail, and completes hardware emulation via constructing System on Programmable Chip (SOPC) in FPGA. Meanwhile, the paper introduces the software flow path, and completes the acquisition, processing, transmission and display of the parallel real-time video signals. Experimental results reveal that the system has a great real-time.
