Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] This embodiment takes Zynq-7045 as an example for illustration, but the present invention is also applicable to Zynq-7100. Zynq-7045 is a SoC device based on Kintex-7FPGA, which provides higher performance and I / 0 speed. XilinxZynq-7045SoC includes Processing System (PS) and Programmable Logic (PL) two parts. where PS is:

[0020] ●Based on dual-core ARM Cortex-A9

[0021] ●CPU frequency up to 1GHz

[0022] ●With NEON accelerator

[0023] ●Single-precision and double-precision floating-point units are supported

[0024] ●32kB instruction and 32kB data L1Cache

[0025] ●512kB L2Cache

[0026] ●PS_DDR3 controller, QSPI controller, static memory controller, interrupt controller

[0027] ●I / O peripherals

[0028] figure 1 An architecture diagram of a zynq7045-based video compression and recorder is given.

Abstract

The invention discloses a video compressor and recorder. The video compressor and recorder comprises a processing module, a PL_DDR3 memory, a PS_DDR3 memory, and a SATA disk, wherein the processing module adopts a Xilinx Zynq-7045 chip or a Xilinx Zynq-7100 chip, and comprises an audio-video compression IP core and a SATA controller; the audio-video compression IP core is used for saving input audio-video data in the PL_DDR3 memory, reading the audio-video data from the PL_DDR3 memory to perform compression encoding, and transmitting the audio-video data subjected to compression encoding to the SATA controller; and the SATA controller is used for firstly sending the compressed audio-video data to the PS_DDR3 memory to cache, and then writing the cached audio-video data into the SATA disk.An original video recording module and a video compression module are combined on one processing module to realize the video compression and recording functions, thereby satisfying the demands of miniaturization and low power consumption.

Description

technical field [0001] The invention relates to a video compression and recorder, in particular to a video compression and recorder with miniaturization and low power consumption. Background technique [0002] In the prior art, video compression and video recording are respectively implemented on two processing boards, and the communication between the two processing boards needs to be performed through PCIe, resulting in the defects of large system volume and high power consumption. Contents of the invention [0003] The object of the invention of the present invention is to provide a kind of video compression and recorder, this video compression and recorder combines original video recording module and video compression module on one processing module, realizes video compression and recording function, and possesses flexible function Interface scalability to meet the needs of miniaturization and low power consumption. [0004] The purpose of the invention of the present...
