An acceleration system and method for multi-channel video encoding and decoding

Abstract

The invention provides an acceleration system and method for multi-channel video encoding and decoding. The system includes a Camera, a Server and an acceleration card. The accelerator card includes a BMC control module, a chip processing module and a power supply module; the BMC control module is used for out-of-band monitoring and management, the chip processing module is used for multi-channel video encoding and decoding, and the power supply module supplies power for the BMC control module and the chip processing module. The chip processing module includes 2, 3 or 4 FPGA chips. The FPGA chips are respectively connected to two DDR4 memory sticks, JTAG circuit, SPI Flash and EMMC. The FPGA chips are interconnected by Chiplink, and the FPGA chips are connected to the Switch. Based on this acceleration system, an acceleration method for multi-channel video encoding and decoding is also proposed. The present invention uses FPGA chip to realize, does not use CPU with video codec function, for example E3 of intel, cooperates with the P4 card of Nvidia, greatly reduces cost. In addition, using 2, 3 or 3 FPGA chips can increase the speed of video encoding and decoding according to actual needs.

Description

technical field [0001] The invention relates to the technical field of server video encoding and decoding, and specifically provides an acceleration system and method for multi-channel video encoding and decoding. Background technique [0002] In recent years, the continuous development of network technology has made our life more and more colorful. With the network as a convenient carrier, multimedia technology has also made rapid progress. As the core and key of multimedia technology, multimedia video codec has made significant progress in technology and application in recent years. The main function of video coding is to compress video pixel data such as RGB or YUV into a video code stream, thereby reducing the amount of video data. [0003] There are more and more requirements for the current video codec application, and the current customers are based on the CPU with video codec function, such as Intel's E3, and Nvidia's P4 card. The current E3 integrated codec chip h...

Problems solved by technology

Moreover, there are only 2 chips in the P4 card for video encoding and decoding. If it is only used as a single application of encoding and decoding, the other computing performance of the P4 card is undoubtedly a waste, and the price of the P4 card is relatively expensive.
