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.
Compiler Compilers

Release Date: 1991-02-12
Advances and problems in the field of compiler compilers are considered in this volume, which presents the proceedings of the third in a series of biannual workshops on compiler compilers. Selected papers address the topics of requirements, properties, and theoretical aspects of compiler compilers as well as tools and metatools for software engineering. The 23 papers cover a wide spectrum in the field of compiler compilers, ranging from overviews of new compiler compilers for generating quality compilers to special problems of code generation and optimization. Aspects of compilers for parallel systems and knowledge-based development tools are also discussed.
Retargetable Compilers for Embedded Core Processors

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.
