为解决图像码流庞大带来的存储和传输困难,提出了一种针对多路图像译码的码流分配决策,并采用VHDL语言来实现。码流分配前,对图像头文件进行检测,采用两片外挂RAM对检测后的码流进行乒乓操作后,送入多路并行图像处理模块,处理后的码流采用同样的分配方式进行缓存。结果表明该决策真正实现了图像码流传输的实时性和准确性,而且其可移植性强,可以应用到图像处理的很多领域,成为提高码流缓存和传输速度的桥梁。
In order to solve the problem of storage and transmission caused by huge image bit-stream, a decision-making algorithm for bit-stream allocation for multi-channel image coding is proposed and implemented in VHDL. Before the code stream is distributed, the image header file is detected. After two pieces of external RAM are used to ping the detected code stream, the multi-channel parallel image processing module is used, and the processed code stream is cached in the same distribution manner. The results show that the decision-making realizes the real-time and accuracy of the image stream transmission, and its portability is strong, and can be applied to many fields of image processing and become a bridge to improve the speed of stream caching and transmission.
