Scalable Parallel Programming Applied to H.264/AVC Decoding available in PDF, EPUB and Kindle. Existing software applications should be redesigned if programmers want to benefit from the performance offered by multi- and many-core architectures. Performance scalability now depends on the possibility of finding and exploiting enough Thread-Level Parallelism (TLP) in applications for using the increasing numbers of cores on a chip. Video decoding is an example of an application domain with increasing computational requirements every new generation. This is due, on the one hand, to the trend towards high quality video systems (high definition and frame rate, 3D displays, etc) that results in a continuous increase in the amount of data that has to be processed in real-time. On the other hand, there is the requirement to maintain high compression efficiency which is only possible with video codes like H.264/AVC that use advanced coding techniques. In this book, the parallelization of H.264/AVC decoding is presented as a case study of parallel programming. H.264/AVC decoding is an example of a complex application with many levels of dependencies, different kernels, and irregular data structures. The book presents a detailed methodology for parallelization of this type of applications. It begins with a description of the algorithm, an analysis of the data dependencies and an evaluation of the different parallelization strategies. Then the design and implementation of a novel parallelization approach is presented that is scalable to many core architectures. Experimental results on different parallel architectures are discussed in detail. Finally, an outlook is given on parallelization opportunities in the upcoming HEVC standard.

Download and read online ebook Parallel Algorithms and Architectures for Low Power Video Decoding write by Vivienne Sze. This book was released on 2010. Parallel Algorithms and Architectures for Low Power Video Decoding available in PDF, EPUB and Kindle. Parallelism coupled with voltage scaling is an effective approach to achieve high processing performance with low power consumption. This thesis presents parallel architectures and algorithms designed to deliver the power and performance required for current and next generation video coding. Coding efficiency, area cost and scalability are also addressed. First, a low power video decoder is presented for the current state-of-the-art video coding standard H.264/AVC. Parallel architectures are used along with voltage scaling to deliver high definition (HD) decoding at low power levels. Additional architectural optimizations such as reducing memory accesses and multiple frequency/voltage domains are also described. An H.264/AVC Baseline decoder test chip was fabricated in 65-nm CMOS. It can operate at 0.7 V for HD (720p, 30 fps) video decoding and with a measured power of 1.8 mW. The highly scalable decoder can tradeoff power and performance across>100x range. Second, this thesis demonstrates how serial algorithms, such as Context-based Adaptive Binary Arithmetic Coding (CABAC), can be redesigned for parallel architectures to enable high throughput with low coding efficiency cost. A parallel algorithm called the Massively Parallel CABAC (MP-CABAC) is presented that uses syntax element partitions and interleaved entropy slices to achieve better throughput-coding efficiency and throughput-area tradeoffs than H.264/AVC. The parallel algorithm also improves scalability by providing a third dimension to tradeoff coding efficiency for power and performance. Finally, joint algorithm-architecture optimizations are used to increase performance and reduce area with almost no coding penalty. The MP-CABAC is mapped to a highly parallel architecture with 80 parallel engines, which together delivers>10x higher throughput than existing H.264/AVC CABAC implementations. A MP-CABAC test chip was fabricated in 65-nm CMOS to demonstrate the power-performance-coding efficiency tradeoff.
