Customizable processors have been described as the next natural step in the evolution of the microprocessor business: a step in the life of a new technology where top performance alone is no longer sufficient to guarantee market success. Other factors become fundamental, such as time to market, convenience, energy efficiency, and ease of customization. This book is the first to explore comprehensively one of the most fundamental trends which emerged in the last decade: to treat processors not as rigid, fixed entities, which designers include "as is� in their products; but rather, to build sound methodologies to tailor-fit processors to the specific needs of such products. This book addresses the goal of maintaining a very large family of processors, with a wide range of features, at a cost comparable to that of maintaining a single processor. First book to present comprehensively the major ASIP design methodologies and tools without any particular bias Written by most of the pioneers and top international experts of this young domain Unique mix of management perspective, technical detail, research outlook, and practical implementation

It is well known that embedded systems have to be implemented efficiently. This requires that processors optimized for certain application domains are used in embedded systems. Such an optimization requires a careful exploration of the design space, including a detailed study of cost/performance tradeoffs. In order to avoid time-consuming assembly language programming during design space exploration, compilers are needed. In order to analyze the effect of various software or hardware configurations on the performance, retargetable compilers are needed that can generate code for numerous different potential hardware configurations. This book provides a comprehensive and up-to-date overview of the fast developing area of retargetable compilers for embedded systems. It describes a large set of important tools as well as applications of retargetable compilers at different levels in the design flow. This text is mostly self-contained and requires only fundamental knowledge in software and compiler design. It is intended to be a key reference for researchers and designers working on software, compilers, and processor optimization for embedded systems.

The building blocks of today's embedded systems-on-a-chip are complex IP components and programmable processor cores. This means that more and more system functionality is implemented in software rather than in custom hardware. In turn, this indicates a growing need for high-level language compilers, capable of generating efficient code for embedded processors. However, traditional compiler technology hardly keeps pace with new developments in embedded processor architectures. Many existing compilers for DSPs and multimedia processors therefore produce code of insufficient quality with respect to performance and/or code size, and a large part of software for embedded systems is still being developed in assembly languages. As both embedded software and processors architectures are getting more and more complex, assembly programming clearly violates the demands for a short time-to-market and high dependability in embedded system design. The goal of this book is to provide new methods and techniques to software and compiler developers, that help to make the necessary step from assembly programming to the use of compilers also in embedded system design.The book discusses the state of the art in the area of compilers for embedded processors. It presents a collection of new code optimization techniques, dedicated to DSP and multimedia processors. These include: compiler support for DSP address generation units, efficient mapping of data flow graphs to irregular architectures, exploitation of SIMD and conditional instructions, and function inlining under code size constraints. Comprehensive experimental evaluations are given for real-life processors, that indicate the code quality improvements which can be achieved as compared to earlier techniques. In addition, C compiler frontend issues are discussed from a practical viewpoint. The book is intended for researchers and engineers active in software development for embedded systems, and for compiler developers in academia and industry.

The market for consumer electronics is characterized by rapidly growing complexities of applications and decreasing market window opportunities. A key concept for coping with such requirements is the reuse of system components. Embedding programmable processors into VLSI systems facilitates reuse and offers a high degree of flexibility. The use of embedded processors, however, poses challenges for software compilers, because real-time constraints and limited silicon area for program memories demand extremely efficient machine code. Additionally there is a need for flexible, retargetable compilers which explore the mutual dependence between processor architectures and program execution speed. Current compiler technology does not meet these demands, particularly the area of DSP where application-specific processors are predominant. As a consequence, the largest part of DSP software is still developed manually at assembly language level. Recent research efforts, located at the intersection of software and hardware design, aim at eliminating this bottleneck.Retargetable Code Generation for Digital Signal Processors outlines the new role of compilers in hardware/software codesign of embedded systems, and it describes the state-of-the-art in the area of retargetable code generation and optimization for embedded DSPs. It presents concepts and algorithmic solutions, which achieve both retargetability and high code quality. In contrast to approaches taken in classical compiler construction, emphasis is put on effective code optimization instead of high compilation speed. The usefulness of the proposed techniques is demonstrated for real-life architectures. This volume presents an integrated solution for retargetable DSP compilers. It covers the whole compilation process, including target processor modelling, intermediate code generation, code selection, register allocation, scheduling and optimization for parallelism. It should be of interest to researchers, senior design engineers and CAD managers both in academia and industry.

We are presently observing a paradigm change in designing complex SoC as it occurs roughly every twelve years due to the exponentially increasing number of transistors on a chip. This design discontinuity, as all previous ones, is characterized by a move to a higher level of abstraction. This is required to cope with the rapidly increasing design costs. While the present paradigm change shares the move to a higher level of abstraction with all previous ones, there exists also a key difference. For the ?rst time shrinking geometries do not leadtoacorrespondingincreaseofperformance. InarecenttalkLisaSuofIBM pointed out that in 65nm technology only about 25% of performance increase can be attributed to scaling geometries while the lion share is due to innovative processor architecture [1]. We believe that this fact will revolutionize the entire semiconductor industry. What is the reason for the end of the traditional view of Moore’s law? It is instructive to look at the major drivers of the semiconductor industry: wireless communications and multimedia. Both areas are characterized by a rapidly increasingdemandofcomputationalpowerinordertoprocessthesophisticated algorithmsnecessarytooptimallyutilizethepreciousresourcebandwidth. The computational power cannot be provided by traditional processor architectures and shared bus type of interconnects. The simple reason for this fact is energy ef?ciency: there exist orders of magnitude between the energy ef?ciency of an algorithm implemented as a ?xed functionality computational element and of a software implementation on a processor.

New software tools and a sophisticated methodology above RTL are required to answer the challenges of designing an optimized application specific processor (ASIP). This book offers an automated and fully integrated implementation flow and compares it to common implementation practice. Case-studies emphasise that neither the architectural advantages nor the design space of ASIPs are sacrificed for an automated implementation. Realizing a building block which fulfils the requirements on programmability and computational power is now efficiently possible for the first time.Optimized ASIP Synthesis from Architecture Description Language Models inspires hardware designers as well as application engineers to design powerful ASIPs that will make their SoC designs unique.

Today more than 90 per cent of all programmable processors are employed in embedded systems. This number is actually not surprising, contemplating that in a typical home you might find one or two PCs equipped with high-performance standard processors, and probably dozens of embedded systems, including electronic entertainment, household, and telecom devices, each of them equipped with one or more embedded processors. The question arises why programmable processors are so popular in embedded system design. The answer lies in the fact that they help to narrow the gap between chip capacity and designer productivity. Embedded processors cores are nothing but one step further towards improved design reuse, just along the lines of standard cells in logic synthesis and macrocells in RTL synthesis in earlier times of IC design. Additionally, programmable processors permit to migrate functionality from hardware to software, resulting in an even improved reuse factor as well as greatly increased flexibility.The LISA processor design platform (LPDP) presented in Architecture Exploration for Embedded Processors with LISA addresses recent design challenges and results in highly satisfactory solutions. The LPDP covers all major high-level phases of embedded processor design and is capable of automatically generating almost all required software development tools from processor models in the LISA language. It supports a profiling-based, stepwise refinement of processor models down to cycle-accurate and even RTL synthesis models. Moreover, it elegantly avoids model inconsistencies otherwise omnipresent in traditional design flows.

Computerarchitecturepresentlyfacesanunprecedentedrevolution: Thestep from monolithic processors towards multi-core ICs, motivated by the ever - creasingneedforpowerandenergyef ciencyinnanoelectronics. Whetheryou prefer to call it MPSoC (multi-processor system-on-chip) or CMP (chip mul- processor), no doubt this revolution affects large domains of both computer science and electronics, and it poses many new interdisciplinary challenges. For instance, ef cient programming models and tools for MPSoC are largely an open issue: "Multi-core platforms are a reality - but where is the software support" (R. Lauwereins, IMEC). Solving it will require enormous research efforts as well as the education of a whole new breed of software engineers that bring the results from universities into industrial practice. Atthesametime,thedesignofcomplexMPSoCarchitecturesisanextremely time-consuming task, particularly in the wireless and multimedia application domains, where heterogeneous architectures are predominant.Due to the - ploding NRE and mask costs most companies are now following a platform approach: Invest a large (but one-time) design effort into a proper core - chitecture, and create easy-to-design derivatives for new standards or product features. Needless to say, only the most ef cient MPSoC platforms have a real chance to enjoy a multi-year lifetime on the highly competitive semiconductor market for embedded systems.

Increasing complexity of modern embedded systems demands system designers to ramp up their design productivity without compromising performance goals. This is promoted by modern Electronic System Level (ESL) techniques. Language-driven Exploration and Implementation of Partially Re-configurable ASIPs addresses an important segment of the ESL area by modeling partially re-configurable processors via high-level Architecture Description Language (ADL). This approach also hints an imminent evolution in the area of re-configurable system design.

Simulation of computer architectures has made rapid progress recently. The primary application areas are hardware/software performance estimation and optimization as well as functional and timing verification. Recent, innovative technologies such as retargetable simulator generation, dynamic binary translation, or sampling simulation have enabled widespread use of processor and system-on-chip (SoC) simulation tools in the semiconductor and embedded system industries. Simultaneously, processor and SoC simulation is still a very active research area, e.g. what amounts to higher simulation speed, flexibility, and accuracy/speed trade-offs. This book presents and discusses the principle technologies and state-of-the-art in high-level hardware architecture simulation, both at the processor and the system-on-chip level.

It gives me immense pleasure to introduce this timely handbook to the research/- velopment communities in the ?eld of signal processing systems (SPS). This is the ?rst of its kind and represents state-of-the-arts coverage of research in this ?eld. The driving force behind information technologies (IT) hinges critically upon the major advances in both component integration and system integration. The major breakthrough for the former is undoubtedly the invention of IC in the 50’s by Jack S. Kilby, the Nobel Prize Laureate in Physics 2000. In an integrated circuit, all components were made of the same semiconductor material. Beginning with the pocket calculator in 1964, there have been many increasingly complex applications followed. In fact, processing gates and memory storage on a chip have since then grown at an exponential rate, following Moore’s Law. (Moore himself admitted that Moore’s Law had turned out to be more accurate, longer lasting and deeper in impact than he ever imagined. ) With greater device integration, various signal processing systems have been realized for many killer IT applications. Further breakthroughs in computer sciences and Internet technologies have also catalyzed large-scale system integration. All these have led to today’s IT revolution which has profound impacts on our lifestyle and overall prospect of humanity. (It is hard to imagine life today without mobiles or Internets!) The success of SPS requires a well-concerted integrated approach from mul- ple disciplines, such as device, design, and application.

This book gives a comprehensive introduction to the design challenges of MPSoC platforms, focusing on early design space exploration. It defines an iterative methodology to increase the abstraction level so that evaluation of design decisions can be performed earlier in the design process. These techniques enable exploration on the system level before undertaking time- and cost-intensive development.

This book introduces a novel design methodology which can significantly reduce the ASIP development effort through high degrees of design automation. The key elements of this new design methodology are a powerful application profiler and an automated instruction-set customization tool which considerably lighten the burden of mapping a target application to an ASIP architecture in the initial design stages. The book includes several design case studies with real life embedded applications to demonstrate how the methodology and the tools can be used in practice for accelerating the overall ASIP design process.

This book describes a flexible and largely automated methodology for adding the estimation of power consumption to high level simulations at the electronic system level (ESL). This method enables the inclusion of power consumption considerations from the very start of a design. This ability can help designers of electronic systems to create devices with low power consumption.  The authors also demonstrate the implementation of the method, using the popular ESL language “SystemC”. This implementation enables most existing SystemC ESL simulations for power estimation with very little manual work. Extensive case-studies of a Network on Chip communication architecture and a dual-core application processor “ARM Cortex-A9” showcase the applicability and accuracy of the method to different types of electronic devices. The evaluation compares various trade-offs regarding amount of manual work, types of ESL models, achieved estimation accuracy and impact on the simulation speed.Describes a flexible and largely automated ESL power estimation method;Shows implementation of power estimation methodology in SystemC;Uses two extensive case studies to demonstrate method introduced.

In this new edition of the Handbook of Signal Processing Systems, many of the chapters from the previous editions have been updated, and several new chapters have been added. The new contributions include chapters on signal processing methods for light field displays, throughput analysis of dataflow graphs, modeling for reconfigurable signal processing systems, fast Fourier transform architectures, deep neural networks, programmable architectures for histogram of oriented gradients processing, high dynamic range video coding, system-on-chip architectures for data analytics, analysis of finite word-length effects in fixed-point systems, and models of architecture. There are more than 700 tables and illustrations; in this edition over 300 are in color.This new edition of the handbook is organized in three parts. Part I motivates representative applications that drive and apply state-of-the art methods for design and implementation of signal processing systems; Part II discusses architectures for implementing these applications; and Part III focuses on compilers, as well as models of computation and their associated design tools and methodologies.
