چکیده
In this paper we present possibilities to parallelize Deblocking Filter (DF) of H.264 video codec and results on Decoupled Threaded Architecture (DTA). We exploited all the available parallelism in the code in order to make it suitable for DTA architecture. Experimental results show that significant speedup can be achieved and that DTA architecture can efficiently exploit available parallelism.

Exploiting Parallelism in the H.264 Deblocking Filter by Operation Reordering
In the H.264 video compression standard, the deblocking filter contributes about one-third of all computation in the decoder. With multiprocessor architectures becoming the future trend of system design, computation time reduction can be achieved if the deblocking filter well apportions its operations to multiple processing elements. In this paper, we apply a 16 pixel long boundary, the basic u...

In the H.264 video compression standard, the deblocking filtering contributes about one-third of all computation in the decoder. With many-core architectures becoming the future trend of system design, computation time can be reduced if the deblocking appropriately apportions its operations to multiple processing elements. In this study, we used a four-pixel-long boundary as the basis for analy...
متن کاملHigh-Throughput Parallel Architecture for H.265/HEVC Deblocking Filter
A novel parallel VLSI architecture is proposed in order to improve the performance of the H.265/HEVC deblocking filter. The overall computation is pipelined, and a new parallel-zigzag processing order is introduced to achieve high throughput. The processing order of the filter is efficiently rearranged to process the horizontal edges and vertical edges at the same time. The proposed H.265/HEVC ...

In this paper, a highly parallel deblocking filter architecture for H.264/AVC is proposed to process one macroblock in 48 clock cycles and give real-time support to QFHD@60 fps sequences at less than 100 MHz. 4 edge filters organized in 2 groups for simultaneously processing vertical and horizontal edges are applied in this architecture to enhance its throughput. While parallelism increases, pi...
متن کاملParallel Deblocking Filter for H.264/AVC on the TILERA Many-Core Systems
For the purpose of accelerating deblocking filter, which accounts for a significant percentage of H.264/AVC decoding time, some studies use wavefront method to achieve the required performance on multi-core platforms. We study the problem under the context of many-core systems and present a new method to exploit the implicit parallelism. We apply our implementation to the deblocking filter of t...
