This book explores near-threshold computing (NTC), a design-space using techniques to run digital chips (processors) near the lowest possible voltage.  Readers will be enabled with specific techniques to design chips that are extremely robust; tolerating variability and resilient against errors.  Variability-aware voltage and frequency allocation schemes will be presented that will provide performance guarantees, when moving toward near-threshold manycore chips.  ·         Provides an introduction to near-threshold computing, enabling reader with a variety of tools to face the challenges of the power/utilization wall; ·         Demonstrates how to design efficient voltage regulation, so that each region of the chip can operate at the most efficient voltage and frequency point; ·         Investigates how performance guarantees can be ensured when moving towards NTC manycores through variability-aware voltage and frequency allocation schemes.  .

This book serves as a reference for researchers and designers in Embedded Systems who need to explore design alternatives.  The MULTICUBE project (an EU Seventh Framework Programme project) has focused on this problem for the past three years and is the basis for this book.  It provides a design space exploration methodology for the analysis of system characteristics and the selection of the most appropriate architectural solution to satisfy requirements in terms of performance, power consumption, number of required resources, etc.  This book focuses on the design of complex applications, where the choice of the optimal design alternative in terms of application/architecture pair is too complex to be pursued through a full search comparison, especially because of the multi-objective nature of the designer’s goal, the simulation time required and the number of parameters of the multi-core architecture to be optimized concurrently.  The methodologies presented have been applied to several application domains to demonstrate their applicability and benefits. First, a high-level modeling and exploration approach has been applied for a powerline communication network based on a SoC, then the application of the automatic DSE flow to parallel on-chip architectures is discussed, and finally the DSE for run-time management has been applied to a reconfigurable system for video streaming. Describes the MULTICUBE Design Space Exploration methodology, which provides a multi-level system specification and modeling framework to provide static and dynamic evaluation of the system-level metrics; Provides a common tool interface composed of several layers that are connected through standardized interfaces; Offers a short path to real design space exploration, through use of industrial design flows for examples and tools; Includes optimizations in areas such as multi-processor architectures, multimedia, power consumption, design time, system-level simulation and profiling, run-time management of resources, etc.  .

Transactions on HiPEAC aims at the timely dissemination of research contributions in computer architecture and compilation methods for high-performance embedded computer systems. Recognizing the convergence of embedded and general-purpose computer systems, this journal publishes original research on systems targeted at specific computing tasks as well as systems with broad application bases. The scope of the journal therefore covers all aspects of computer architecture, code generation and compiler optimization methods of interest to researchers and practitioners designing future embedded systems. This 5th issue contains extended versions of papers by the best paper award candidates of IC-SAMOS 2009 and the SAMOS 2009 Workshop, colocated events of the 9th International Symposium on Systems, Architectures, Modeling and Simulation, SAMOS 2009, held in Samos, Greece, in 2009. The 7 papers included in this volume were carefully reviewed and selected. The papers cover research on embedded processor hardware/software design and integration and present challenging research trends.
