This work presents an efficient adaptive tile partitioning algorithm for HEVC decoder parallelization, which divides a video frame into tiles that are processed independently and concurrently on multi-cores. The proposed algorithm is designed to not only increase decoding performance and energy efficiency, but also enhance the video quality by efficiently balancing the workloads of tiles among cores...
Novel approaches to parallel H.264 decoder for symmetric multicore processors are presented. The basic partitioning of the decoder is coarse-grained and hybrid method of the data partitioning and functional partitioning. We investigate the performance bottleneck of the parallelized decoder, and propose two new approaches, software memory throttling and fair load balancing. The software memory throttling...
We propose a new method for H.264/AVC parallel decoder implementation on the CELL Broadband Engine processor. To decode the full HD H.264 stream in real time, the high performance processing is required due to the high computation and complexity. Our decoder exploits the functional partition method to parallelize the H.264 decoder on multicore platform. The load of performance critical module is dynamically...
Emerging video coding technology like H.264/AVC achieves high compression efficiency, which enables high quality video at the same or lower bitrate. However, those advanced coding techniques come at the cost of more computational power. Developed with such multimedia applications in mind, the CELL broadband engine (BE) processor was designed as a heterogeneous on-chip multicore processor to meet the...
