In this paper, we study different schemes to parallelize trellis algorithms for efficient implementation on a GPU. We consider parallelization schemes at the packet-level, subblock-level and trellis-level to increase the number of threads in a GPU implementation. At the trellis-level, we consider state-level, forward-backward traversal and branch-metric parallelism. To evaluate the performance of...
This paper presents a parallel and scalable solution for adaptive deblocking filtering in H.264/AVC. While traditionally in deblocking filtering, the edges in a macroblock are processed in a sequential order, this paper demonstrates how algorithm modifications can be used to enable processing multiple consecutive edges at the same time. The proposed method increases the throughput in proportion to...
In recent years, the mobile phone industry has become one of the most dynamic technology sectors. The increasing demands of multimedia services on the cellular networks have accelerated this trend. This paper presents a low power SIMD architecture that has been tailored for efficient implementation of H.264 encoder/decoder kernel algorithms. Several customized features have been added to improve the...
