摘要
尽管以往有很多文章对基于DCT的和基于任意形状的提升小波的mpeg4编码效益进行了比较,但大多数的实验都是在PC机上进行的,在专用的DSP芯片上的算法效益上的比较还是空白。文中借此阐述了传统的基于DCT和基于任意形状的提升小波算法的mpeg4编码的基本原理,介绍了TM1300处理器的硬件结构特色,在TM1300上对视频序列分别运用了基于MPEG4的DCT,以及基于任意形状的提升小波的变换编码算法。文中对这两种算法原理和结果分别进行了分析和比较,并提出了较为适合的算法。
Although there were many articles had compared the effects of MPEG4 transformation based on DCT and the transformation based on lifting-wavelet,most of them are realized just on person computer using the general CPU.So it is almost blank in the field of results running on the particular CPU.This article expatiated the coding principle of MPEG4 and lifting-wavelet,related the particulars of CPU of TM1300,and adopted DCT and Lifting-wavelet transformation to realize the coding of MPEG4 on TM1300,then compared the results and got some more suitable conclusion.
