Implementation Of Inverse Quantization And Inverse Transform Of Avs On DSP

描述了AVS中的反量化和反变换算法的DSP实现。采用TI公司的TMS320C5502作为处理芯片,根据芯片的结构、汇编指令、存储器读取的特点,针对视频解码的实时性要求,给出了一种适合该芯片的快速实现方法。通过DSP的仿真验证,对比了几种实现方法,证明了这一方法的可行性和高效性,最后将给出实验结果及分析。

The fast implementation of the inverse quantization and inverse transform of AVS on DSP is presented, which is designed on TMS320C5502 from TI. The design is based on the characteristics of the chip, assembly instructions and the operation of the memorizer. It is developed for the Real-time work. By the experiment from DSP and the contrast of several methods, the results at last shows the great feasibility and efficiency of this design.
