dc.description.abstract | A high-performance VLSI architecture for the H.264/AVC context-adaptive variable-length decoder (CAVLD) is proposed in order to reduce the computation time. The overall computation is pipelined, and a parallel processing is employed for high performance. For the run before computation, the values of input symbols are estimated in parallel to check if their computation can be skipped in advance. Experimental results show that the performance of run before is improved by 134% on average when four symbols are estimated in parallel, while the area of the VLSI implementation is only increased by 12% compared to a sequential method. The degree of parallelism employed for the estimation module is 4, and it can be changed easily. H.264/AVD is an essential technology for the multimedia engines of many consumer electronics applications, such as D-TVs and mobile devices. The proposed method contributes to the performance improvement of those applications. | - |
