摘要
针对工业、交通视频监控环境中视频流的压缩处理速度慢,严重影响系统性能现状。提出一种基于DSP的快速视频流压缩处理技术,首先通过硬件上的合理设计,充分发挥DSP硬件资源性能,设计优化的线形汇编指令段,提高视频流的并行处理能力。然后对视频流的压缩编解码算法进行研究与改进,提出适于DSP的快速视频流处理算法。
In view of the low compression processing speed of video flow and thus the serious influence on the system performance in many industries and transportation video frequency monitoring, a kind of fast video f lows compression processing technology based on the DSP is proposed. By proper hardware design, giving full play to the DSP hardware resources performance and optimizing, the linear assembly instruction section, the parallel processing ability of the video flows is raised. And then some research and improvement is carried out on the decoding algorithm .The proposed fast video processing algorithm is proved suitable for DSP.
