Video Processing Unit

The DSP is the video processing core unit ; And the video capture unit , the video pre-processing unit , the video display unit are implemented in the FPGA .

系统中DSP承担核心的视频图像处理任务，而FPGA则作为视频采集单元，预处理单元以及视频显示单元。

Then , Chapter four describes the details of the implementation of video processing subsystem from processor unit , storage architecture unit , data I / O host-slave bus , data I / O interconnection unit four design aspects .

第四章从处理器单元设计、存储结构单元设计、数据I／O主从总线设计，数据I／O互连总线设计和系统控制中心单元设计五个方面分析视频处理子系统的详细设计。

After introducing the standard of digital video compressing and the arithmetic of JPEG , this thesis researches the technology of video signal capturing and processing unit which is based on JPEG standard .

本文在介绍了数字视频图像压缩标准和JPEG压缩算法后，针对图像监控的场合，研究了基于JPEG标准的视频采集处理单元相关的技术，并完成了基于ARM的JPEG的图像采集压缩单元设计。
