This book was released on 2013-03-09 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The building blocks of today's and future embedded systems are complex intellectual property components, or cores, many of which are programmable processors. Traditionally, these embedded processors mostly have been pro grammed in assembly languages due to efficiency reasons. This implies time consuming programming, extensive debugging, and low code portability. The requirements of short time-to-market and dependability of embedded systems are obviously much better met by using high-level language (e.g. C) compil ers instead of assembly. However, the use of C compilers frequently incurs a code quality overhead as compared to manually written assembly programs. Due to the need for efficient embedded systems, this overhead must be very low in order to make compilers useful in practice. In turn, this requires new compiler techniques that take the specific constraints in embedded system de sign into account. An example are the specialized architectures of recent DSP and multimedia processors, which are not yet sufficiently exploited by existing compilers.

Download or read book A Just in Time Register Allocation and Code Optimization Framework for Embedded Systems written by Sathyanarayan Thammanur and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile programs are being used extensively to be run on embedded systems. These programs typically needs to be downloaded as code slices onto the embedded device. Code slices on embedded system would be compiled "just-in-time" and run. Code size is an important issue for such embedded systems. Register allocators in current literature have always targeted speed of execution as their key issue and hence are not suited for embedded systems. We describe a "just-in-time", usage density based register allocator geared towards systems with limited general purpose register set wherein speed, code size and memory requirements are equally of concern. The main attraction of the allocator is that it does not make use of the traditional live range and interval analysis nor performs advanced optimizations based on range splitting or spilling but results in very good code quality. We circumvent the need for traditional analysis by using a measure of usage density of a variable. The usage density of a variable at a program point represents both the frequency and the density of the uses. We contend that using this measure we can capture both range and frequency information which is essentially used by the good allocators based on splitting and spilling. We describe a two-pass framework based on this measure which has a linear complexity in terms of the program size. We perform comparisons with the static allocators based on graph coloring and the ones targeted towards dynamic compilation systems like linear scan of live ranges. We have implemented our allocator inside the tcc compiler. We find that the usage density allocator generates a better code quality than the other allocators for smaller set of registers. Our results show an improvement over Briggs-style allocator in reducing code size of up to 12% for a register set of size 16 in some cases. The results are interesting with decreasing register set size in terms of both code size as well as memory requirements. The algorithm is of interest in applications where speed, code size and the memory requirements are all equally of concern like embedded processors with limited general purpose register set and "just-in-time" compilers. To optimize the code size further, we also developed a Dynamic Dead Code Elimination framework which selectively removes branches within the loops and reduces the mobile code slice to be transmitted to the embedded device. We found that there were some opportunities that were exploited by this framework. We present the results for the same.

This book was released on 2010-09-24 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: For real-time systems, the worst-case execution time (WCET) is the key objective to be considered. Traditionally, code for real-time systems is generated without taking this objective into account and the WCET is computed only after code generation. Worst-Case Execution Time Aware Compilation Techniques for Real-Time Systems presents the first comprehensive approach integrating WCET considerations into the code generation process. Based on the proposed reconciliation between a compiler and a timing analyzer, a wide range of novel optimization techniques is provided. Among others, the techniques cover source code and assembly level optimizations, exploit machine learning techniques and address the design of modern systems that have to meet multiple objectives. Using these optimizations, the WCET of real-time applications can be reduced by about 30% to 45% on the average. This opens opportunities for decreasing clock speeds, costs and energy consumption of embedded processors. The proposed techniques can be used for all types real-time systems, including automotive and avionics IT systems.

Download or read book Source Code Optimization Techniques for Data Flow Dominated Embedded Software written by Heiko Falk and published by Springer Science & Business Media. This book was released on 2013-03-19 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on source-to-source code transformations that remove addressing-related overhead present in most multimedia or signal processing application programs. This approach is complementary to existing compiler technology. What is particularly attractive about the transformation flow pre sented here is that its behavior is nearly independent of the target processor platform and the underlying compiler. Hence, the different source code trans formations developed here lead to impressive performance improvements on most existing processor architecture styles, ranging from RISCs like ARM7 or MIPS over Superscalars like Intel-Pentium, PowerPC, DEC-Alpha, Sun and HP, to VLIW DSPs like TI C6x and Philips TriMedia. The source code did not have to be modified between processors to obtain these results. Apart from the performance improvements, the estimated energy is also significantly reduced for a given application run. These results were not obtained for academic codes but for realistic and rep resentative applications, all selected from the multimedia domain. That shows the industrial relevance and importance of this research. At the same time, the scientific novelty and quality of the contributions have lead to several excellent papers that have been published in internationally renowned conferences like e. g. DATE. This book is hence of interest for academic researchers, both because of the overall description of the methodology and related work context and for the detailed descriptions of the compilation techniques and algorithms.

This book was released on 2013-03-09 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 important tools as well as applications of retargetable compilers at different levels in the design flow. Retargetable Compiler Technology for Embedded Systems 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.

This book was released on 2013-03-14 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern electronics is driven by the explosive growth of digital communications and multi-media technology. A basic challenge is to design first-time-right complex digital systems, that meet stringent constraints on performance and power dissipation. In order to combine this growing system complexity with an increasingly short time-to-market, new system design technologies are emerging based on the paradigm of embedded programmable processors. This concept introduces modularity, flexibility and re-use in the electronic system design process. However, its success will critically depend on the availability of efficient and reliable CAD tools to design, programme and verify the functionality of embedded processors. Recently, new research efforts emerged on the edge between software compilation and hardware synthesis, to develop high-quality code generation tools for embedded processors. Code Generation for Embedded Systems provides a survey of these new developments. Although not limited to these targets, the main emphasis is on code generation for modern DSP processors. Important themes covered by the book include: the scope of general purpose versus application-specific processors, machine code quality for embedded applications, retargetability of the code generation process, machine description formalisms, and code generation methodologies. Code Generation for Embedded Systems is the essential introduction to this fast developing field of research for students, researchers, and practitioners alike.

This book was released on 2013-03-09 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Embedded core processors are becoming a vital part of today's system-on-a-chip in the growing areas of telecommunications, multimedia and consumer electronics. This is mainly in response to a need to track evolving standards with the flexibility of embedded software. Consequently, maintaining the high product performance and low product cost requires a careful design of the processor tuned to the application domain. With the increased presence of instruction-set processors, retargetable software compilation techniques are critical, not only for improving engineering productivity, but to allow designers to explore the architectural possibilities for the application domain. Retargetable Compilers for Embedded Core Processors, with a Foreword written by Ahmed Jerraya and Pierre Paulin, overviews the techniques of modern retargetable compilers and shows the application of practical techniques to embedded instruction-set processors. The methods are highlighted with examples from industry processors used in products for multimedia, telecommunications, and consumer electronics. An emphasis is given to the methodology and experience gained in applying two different retargetable compiler approaches in industrial settings. The book also discusses many pragmatic areas such as language support, source code abstraction levels, validation strategies, and source-level debugging. In addition, new compiler techniques are described which support address generation for DSP architecture trends. The contribution is an address calculation transformation based on an architectural model. Retargetable Compilers for Embedded Core Processors will be of interest to embedded system designers and programmers, the developers of electronic design automation (EDA) tools for embedded systems, and researchers in hardware/software co-design.

Download or read book Compiler Design written by Sebastian Hack and published by Springer. This book was released on 2016-05-09 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: While compilers for high-level programming languages are large complex software systems, they have particular characteristics that differentiate them from other software systems. Their functionality is almost completely well-defined – ideally there exist complete precise descriptions of the source and target languages. Additional descriptions of the interfaces to the operating system, programming system and programming environment, and to other compilers and libraries are often available. The final stage of a compiler is generating efficient code for the target microprocessor. The applied techniques are different from usual compiler optimizations because code generation has to take into account the resource constraints of the processor – it has a limited number of registers, functional units, instruction decoders, and so on. The efficiency of the generated code significantly depends on the algorithms used to map the program to the processor, however these algorithms themselves depend not only on the target processor but also on several design decisions in the compiler itself – e.g., the program representation used in machine-independent optimization. In this book, the authors discuss classical code generation approaches that are well suited to existing compiler infrastructures, and they also present new algorithms based on state-of-the-art program representations as used in modern compilers and virtual machines using just-in-time compilation. This book is intended for students of computer science. The book is supported throughout with examples, exercises and program fragments.
