Embodiment Construction

[0029] The specific embodiment of the present invention is: the PCI communication monitoring system based on FPGA and DSP chip receives multi-channel compressed video stream from the network through the upper computer application program module, and passes through a DMA channel in the PCI interface module in serial mode according to a certain agreement It is transmitted to the FPGA, and the video stream will be identified in the FPGA according to the protocol, and stored in the DPRAM developed in the video cache module respectively. When the video data stored in the DPRAM meets certain conditions, the DSP will take the video data through the EMIF interface and decompress it. The decompressed video data will be transmitted to the video processing module in the FPGA through the video ports of the respective DSPs. The video processing module will convert the video data format, scale and superimpose and output the integrated video stream all the way to the output video buffer modul...

Abstract

The invention discloses a PCI communication monitoring system based on FPGA and DSP chips. The system is formed by a hardware portion and a software portion. The hardware portion comprises a PC upper computer, a FPGA chip, a DSP chip, a FLASH register and a DDR2 register. The software portion comprises an upper computer application program module, a PCI interface module, a video cache module, a video processing module, a synchronization module, a clock reset module and a DSP decompression module. The PC upper computer is combined with the upper computer application program module so as to complete video receiving, display and man-machine interaction effects together. The FLASH register and the DDR2 register are used for caching video data and a system file. By using the system, advantages of a high integrated level, multiple sources, high definition and intelligence are possessed.
