In this paper, we propose a multilevel parallel intra coding for H.264/AVC based on computed unified device architecture (CUDA). The proposed parallel algorithm improves the parallelism between 4x4 blocks within a macro block (MB) by throwing off some inappreciable prediction modes. By partitioning a frame into multi-slice, the parallelism between MBs can be exploited. In addition, a scalable parallel...
This article presents an efficient parallel CAVLC encoder for H.264/AVC based on GPU. By optimizing the architecture of the encoder, three kinds of dependences are eliminated or weakened, including the context dependence, the memory accessing dependence, and the control dependence. We divide the execution of CAVLC into three stages: two scans, component-oriented coding, and lag packing. For each stage,...
