In general, a large number of the memory accesses are required to decode the CAVLC in H.264/AVC. This is a serious problem for applications such as a DMB and videophone services because of the considerable amount of power that is consumed in accessing the memory. In order to overcome this problem, we propose an efficient coeff_token VLD and a new run_before VLD based on arithmetic operations. The simulation results show that the proposed algorithm achieves an approximate 65-88% savings in memory access without degrading video quality as compared to the conventional CAVLC decoding.
