Abstract
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 run_before decoding method, In the proposed method, the memory access is removed by using a FSM with arithmetic operations. The simulation results show that the proposed algorithm does not degrade video quality is not degraded as well as the power is saved.
