Acceleration of Bioinformatics Sequence Alignment

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Biological sequence alignment is an important and challenging task in bioinformatics. Alignment may be defined as an arrangement of two or more DNA or protein sequences to highlight the regions of their similarity. Sequence alignment is used to infer the evolutionary relationship between a set of protein orDNA sequences. An accurate alignment can provide valuable information for experimentation on the newlyfound sequences. It is indispensable in basic research as well as in practical applications such aspharmaceutical development, drug discovery, diseaseprevention and criminal forensics. Many algorithms and methods, such as, dot plot, Needleman-Wunsch, Smith-Waterman, FASTA, BLAST, HMMERand ClustalW have been proposed to perform and accelerate sequence alignment activities. However, with the ever increasing volume of data in bioinformatics databases, the time needed for biological sequence alignment is always increasing. The main aim of the topics presented in this book is to explore and analyze the existing sequence alignment methods and come up with better and optimized solutions. ····· 10361118628

Recursive Variable Expansion

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Reconfigurable computing, in which a general purpose processor (GPP) is augmented with one or more FPGAs, is increasingly used for high-performance computing where massive fine-grain parallelism and pipelining can be exploited. This book proposes a novel transformation called Recursive Variable Expansion (RVE) for reconfigurable computing, which can be applied to an important category of loops. RVE removes all data dependences in an expression. Hence, it can provide more parallelism as compared to the existing loop transformations. Each chapter of this book contains a simple motivational example to understand the basic problem. Later, the problem and its solution is discussed in more technical depth. Finally, the idea is supported by results on the relevant kernels. The contents of the book is useful for researchers and practitioners involved in getting high performance from Reconfigurable Systems. ····· 10361115161

System Level Design

für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
The complexity of embedded systems is exploding into two interrelated but independently growing directions: architectures complexity/heterogeneity and applications complexity. On the other hand, time- to-market and design productivity factors are constantly shrinking. Consequently, the gap between system complexity and design productivity is constantly increasing. To reduce this gap, System Level Design (SLD) has shown a lot of potential. However, it still involves a substantial number of design challenges. For example, complex applications should be analyzed at higher abstraction level without any architecture directives to provide application-architecture mapping guidelines. Fast performance estimation techniques at cycle-accurate level are required to estimate the software performance on the target architecture. Similarly, the performance analysis of parallel execution on heterogeneous architectures without performing HW/SW co-simulation is an increasingly challenging problem. This book explores the holistic view of SLD to ensure an optimal and rapid design of embedded systems. ····· 10361115140

This dissertation explores the birth and evolution of the personal computing industry and, in particular, Intel as a corporation. Founded by Gordon Moore and Robert Noyce in 1968, Intel was initially destined to produce large-scale semiconductor memories. However, fierce competition in the memory market coupled with the rising potential of the microprocessor market in the early 1980`s prompted Intel to shift its core business. The corporation has never looked back since, and Intel revolutionized the personal computing industry with the introduction of its x86 series of microprocessors. Intel continues to miraculously double its microprocessor performance year after year, and remains a dominant force in the personal computing industry. Various tools, models, and frameworks were utilized to understand, analyze, and characterize the corporation and its related ecosystem. Intel`s internal strengths and weaknesses are evaluated, and its external opportunities and threats noted. Business, competitive, and corporate level strategies are formulated in the basis of this evaluation, and the implementation of the different methodologies is illustrated. ····· 10361113644

High-level platform modeling and exploration

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
One advantage of using a virtual platform over real hardware for embedded software development and testing is the ability of some simulators to take checkpoints of their state. If the entire system model is detailed enough, it might take several minutes (or hours) to simulate booting the O.S. If a snapshot of the simulation is saved just after it has finished booting, each time it is necessary to run the embedded software, designers can simply restore the snapshot and go. Restarting a checkpoint typically takes a few seconds. In this book we present our work on adding a description level language as SystemC to two Virtual Platforms. This work was done for a commercial Virtual Platform, and later translated to a open-sourced Platform. This book also presents a set of modifications to SystemC language to support checkpointing. These modifications will make it possible to take the state of a SystemC running simulation and save it to disk. Later, the same simulation can be restored to the same point it was before, without any change to the simulated modules. These changes would help SystemC to be suitable for use by Virtual Platforms as a description language. ····· 10361113627

UNIFICATION OF VLSI PARTITIONING

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
As VLSI circuits become larger and more complex, the need to improve design automation tools becomes more urgent. Interconnect effects dominate performance and power in the Deep Submicron regime, and Computer Aided Design tools and methodologies need to focus more on interconnect optimization. In addition, there is a push for dramatic levels of on-chip integration in modern circuits. The cumulative effects of the two make design of leading-edge electronic products difficult. In this work, we propose improved techniques and methodologies for layout design of modern VLSI chips. These techniques can be classified as floorplanning, mixed-size placement and VLSI placement for physical synthesis. The proposed algorithms address novel problem formulations and design concerns that arise in modern VLSI designs. ····· 10361113416

Energy-aware address generation optimization

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Nowadays Embedded Systems require high performance specific computations, usually with real-time and Quality of Service constraints, which should run at a low energy level to extend battery life and avoid heating. Very Long Instruction Word (VLIW) processors are a good solution providing enough computational performance at low power with the required programmability to meet short time-to-market restrictions. For those architectures with a high number of computational resources running in parallel the access to data is becoming the main bottleneck that limits the available parallelism. The purpose of this work is to prove that optimizing address generation is an effective of accessing data while decreasing execution time and energy consumption. First, this work evaluates the effectiveness of VLIW processors and presents the architectural exploration framework used for the experiments. It also presents a systematic classification of address generators, a review of literature according to the classification of the different optimizations on the address generation process and a step-wise methodology that gradually reduces energy. ····· 10361113387

Watermarking Techniques for Intellectual Property Protection in SOC

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Sharing Intellectual Property (IP) blocks in today`s competitive market poses significant high security risks. Creators and owners of IP designs want assurances that their content will not be illegally redistributed by consumers, and consumers want assurances that the content they buy is legitimate. Recently, digital watermarking emerged as a candidate solution for copyright protection of IP blocks. In this book, we propose a new approach for watermarking IP designs based on the embedding of the ownership proof as part of the IP design`s finite state machine (FSM). The approach utilizes coinciding as well as unused transitions in the state transition graph of the design. Based on this approach, we have developed a robust watermarking framework, used for copyright protection, as well as fragile watermarking framework used for design authentication. For both frameworks, we developed related algorithms for watermark insertion and extraction. The developed techniques increase the robustness of the watermark and allow a secure implementation, hence enabling the development of the first public-key IP watermarking scheme at the FSM level. ····· 10361102710

Video compression is an active area for potential research. Due to the limitations in the available bandwidth and storage space for high quality multimedia content like - video broadcasting and DVD video data, video compression has become very much necessary to keep up the ever growing demand, yet maintaining the quality in decoded video. Motion Estimation technique in a video coder takes advantage of the temporal redundancy present in video data to achieve substantial compression. The block matching efficiency of the Motion Estimation algorithm, feasibility for hardware implementation and multiple frame storage delays are some of the key challenges faced in implementing a Motion Estimation block. In this work, a software model of Motion Estimation block for H.264 Advanced Video Coder is designed. One Step Search Motion Estimation algorithm is chosen for hardware modeling. The architecture of the model is designed to maximize the throughput of the system by using dual residual energy computation and comparison units for parallel processing of frame data. The hardware model is succesfully implemented and tested on Xilinx Virtex-4 FPGA. ····· 10361101303

Power and Thermal Management in Multicores

für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Thermal and power related issues are common in most modern microprocessors. We are not only talking about servers, but also mobile devices, desktop computers, laptop, GPUs, APUs, etc. For many years microprocessor design has been (and is) limited by power dissipation and temperature. Many studies refer to these key factors as the `Power Wall`. Even today, this `Power Wall` is still limiting the number of cores that can be placed on the same die. In this project we worked in the design, implementation and testing of microarchitecture techniques for accurately adapting the processor performance to power constraints in the single core scenario, multi-core scenario and 3D die-stacked core scenario. We first introduce `Power-Tokens`, to approximate the power being consumed by the processor in real time. Later we will discuss different mechanisms based on pipeline throttling, confidence estimation, instruction criticality information, to adapt the processor to a predefined power budget. ····· 1036120457

Multiprocessor Systems-on-Chip (MPSoC) offer superior performance while maintaining flexibility and reusability thanks to software oriented personalization. While most MPSoCs are today heterogeneous for better meeting the targeted application requirements, homogeneous MPSoCs may become in a near future a viable alternative bringing other benefits such as run-time load balancing, task migration and dynamic frequency scaling. This book relies on a homogeneous NoC-based MPSoC platform developed for exploring scalable and adaptive on-line continuous mapping techniques. Each processor of this system is compact and runs a tiny preemptive operating system that monitors various metrics and is entitled to take remapping decisions through code migration techniques and dynamic frequency scaling. This approach that endows the architecture with decisional capabilities permits refining application implementation at run-time according to various criteria. ····· 1036119728
