Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The increasing demand of decoding high-quality videos can lead to a challenging com-putational requirement for conventional Central Processing Unit (CPU) architectures.Graphics Processing Units (GPUs) in general provide higher computational powerthan CPUs. Efficient GPU execution, however, requires massive parallelism and little ex-ecuting divergence, two criteria are not fully met by all video decoding kernels. This thesisexploits how GPUs can be effectively used in video decoding applications. The challengesinclude proper workload distribution between the CPU and GPU, task optimizations ontwo heterogeneous devices, and efficient communication between them.A complete parallel HEVC decoder was proposed for heterogeneous CPU+GPUsystems. We exploited available decoding parallelism on the CPU, GPU, and between thetwo devices simultaneously. On top of the parallel design, two workload balancing schemeswere implemented, in order to adapt computation resource variation on CPU and GPU.In addition, an energy measurement module was developed for energy efficiency analysis.Evaluated results showed that suitable decoding kernels can be accelerated substan-tially (up to 28.2×) on GPUs at the kernel level. At the application level, using GPUarchitecture can provide significant acceleration when only a low number (1 to 8) of CPUcores are available. On a system consisting of an NVIDIA Titan X Maxwell GPU and anIntel Xeon E5-2699v3 CPU, with four CPU cores, the proposed HEVC decoder delivers167 frames per second for 4K videos, corresponding to a speedup of 2.2× over the state-of-the-art CPU decoder using four CPU cores. When more CPU cores (>8) are employed,the benefit of using GPU vanishes and the performance is eventually outperformed by theCPU decoder due to GPU overloading. With respect to energy, because of its high powerconsumption GPU architecture is not as efficient as the CPU for HEVC decoding.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Mechanics of Advanced Functional Materials emphasizes the coupling effect between the electric and mechanical field in the piezoelectric, ferroelectric and other functional materials. It also discusses the size effect on the ferroelectric domain instability and phase transition behaviors using the continuum micro-structural evolution models. Functional materials usually have a very wide application in engineering due to their unique thermal, electric, magnetic, optoelectronic, etc., functions. Almost all the applications demand that the material should have reasonable stiffness, strength, fracture toughness and the other mechanical properties. Furthermore, usually the stress and strain fields on the functional materials and devices have some important coupling effect on the functionality of the materials. Much progress has been made concerning the coupling electric and mechanical behaviors such as the coupled electric and stress field distribution in piezoelectric solids, ferroelectric domain patterns in ferroelectrics, fracture and failure properties under coupled electric and stress field, etc. The book is intended for researchers and postgraduate students in the fields of mechanics, materials sciences and applied physics who are interested to work on the interdisciplinary mathematical modeling of the functional materials.Prof. Biao Wang is the Dean of School of Physics and Engineering of the Sun Yat-sen University, China.
