摘要
介绍一种以高速定点DSP芯片DM642为核心的雾天实时视频图像处理系统的软硬件设计。系统采用Retinex理论作为算法核心,针对处理算法中大数据量、高速传输、复杂运算的特点,运用查表、EDMA、软件流水等方法进行了大量优化。实验结果表明,具有满意的处理效果和实时性。
This paper introduces the hardware and software development for a real-time fog video processing system which makes the high-performance fixed-point digital signal processor（DSP） as the core.The system adopts Retinex as the algorithm,and chooses the method of look-up table,enhanced direct-memory-access（EDMA）,software pipelining to do amount of optimizations for the algorithm features such as： large number of data,high-speed data transmission,and complex calculation.All of these reach the satisfied result and real-time performance.
