Implementation of fast HEVC encoder based on SIMD and data-level parallelism

This paper presents several optimization algorithms for a High Efficiency Video Coding (HEVC) encoder based on single instruction multiple data (SIMD) operations and data-level parallelism. Based on the analysis of the computational complexity of HEVC encoder, we found that interpolation filter, cost function, and transform take around 68% of the total computation, on average. In this paper, se...

Optimisation of Multimedia Applications for the Philips Wasabi Multiprocessor System

Libavcodec is an open source software library that contains many different audio/video codecs. In this work, it is optimised and parallelised for the Philips Wasabi chip multiprocessor, which is currently being developed at Philips. Wasabi contains several DSPs and one or more general-purpose processors. The TriMedia-style optimisations (in particular utilising the SIMD custom operations) impro...

On the Development and Optimization of HEVC Video Decoders Using High-Level Dataflow Modeling

With the emergence of the High Efficiency Video Coding (HEVC) standard, a dataflow description of the decoder part was developed as part of the MPEGB standard. This dataflow description presented modest framerate results which led us to propose methodologies to improve the performance. In this paper, we introduce architectural improvements by exposing more parallelism using YUV and frame-based ...

A novel architecture for parallel multi-view HEVC decoder on mobile device

The multi-view HEVC (MV-HEVC) extension was finalized in July of 2014 by the Moving Picture Experts Group and the Video Coding Experts Group. Recently, multi-view videos based on stereo representations are becoming widely popular. Also, a variety of multimedia contents are now available for mobile devices. A real-time multi-view video decoder is therefore needed. In mobile devices, a real-time ...
