| Abstract: | Considering the characteristics of DSP TMS320DM642, a fast algorithm of CAVLC decoder is presented and implemented by extending code words, regrouping the code table and linear assembly language.Experimental results on platform of SEED-VPM642 show that decoding speed of this new algorithm is increased by about 66.5%, and this algorithm is effective in real-time video decoding system. |
