Abstract

The invention discloses a high-performance video processing and transmitting system based on a Zynq platform. The system is arranged between an external video source and an upper PC machine, and mainly comprises a video input module, used for collecting valid data in an external video source signal; a VDMA module, used for transmitting video signals in a programmable logic (PL) module to a storage at high speed; a video processing module, used for completing a complex video processing function; an AXI interconnection module, used for connecting the PL module with a processing (PS) system; the PS system, used for controlling the managing the whole system; and a PCIe module, used for packaging video frame data into a corresponding PCIe message, and transmitting the data between the system and the upper PC computer at high speed via a PCIe bus. The system of the invention integrates the capacities of collecting, processing and transmitting high-definition videos at high speed, and has the advantages of being strong in processing capacity, high in video quality and fast in transmission speed.

Description

technical field [0001] The invention relates to video processing technology and communication technology, in particular to a high-definition video processing and transmission system based on Zynq platform. Background technique [0002] With the development of the national economy and the progress of society, the requirements for video clarity, stability and real-time performance are getting higher and higher in the fields of radio and television, intelligent transportation, immersive display, security monitoring, etc. At the same time, the bandwidth of high-definition video signals is high High-definition image acquisition, processing and transmission have also become difficult due to the characteristics of large data throughput and high data throughput. Therefore, the demand for high-performance video processing and transmission systems is also increasing. [0003] On the one hand, the early video processing solutions were mostly realized by ARM, DSP, and FPGA single archit...
