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 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 Software Engineering for Embedded Systems written by Mike Brogioli and published by Elsevier Inc. Chapters. This book was released on 2013-04-01 with total page 1200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimization metrics for compiled code are not always measured in resulting execution clock cycles on the target architecture. Consider a modern cellular telephone or wireless device which may download executables over a wireless network connection or backhaul infrastructure. In such cases, it is often advantageous for the compiler to reduce the size of the compiled code which must be downloaded to the wireless device. By reducing the size of the code needed to be downloaded, savings are achieved in terms of bandwidth required for each wireless point of download. Optimization metrics such as the memory system performance of compiled code are other metrics which are often important to developers. These are metrics correlated to the dynamic run-time behavior of not only the compiled code on the target processor, but also the underlying memory system, caches, DRAM and buses, etc. By efficiently arranging the data within the application or, more specifically, the order in which data and corresponding data structures are accessed by the application dynamically at run-time, significant performance improvements can be gained at the memory-system level. In addition, vectorizing compilers can also improve performance due to spatial locality of data when SIMD instruction sets are present and varying memory-system alignment conditions are met.

Download or read book Software Engineering for Embedded Systems written by Robert Oshana and published by Elsevier Inc. Chapters. This book was released on 2013-04-01 with total page 1200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Code optimization is a critical step in the development process as it directly impacts the ability of the system to do its intended job. Code that executes faster means more channels, more work performed and competitive advantage. Code that executes in less memory enables more application features to fit into the cell phone. Code that executes with less overall power consumption increases battery life or reduces money spent on powering a base station. This chapter is intended to help programmers write the most efficient code possible, whether that is measured in processor cycles, memory, or power. It starts with an introduction to using the tool chain, covers the importance of knowing the embedded architecture before optimization, then moves on to cover a wide range of optimization techniques. Techniques are presented which are valid on all programmable architectures – C-language optimization techniques and general loop transformations. Real-world examples are presented throughout.

Download or read book Retargetable Compilers for Embedded Core Processors written by Clifford Liem and published by Springer Science & Business Media. 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.
