ARM System Developer's Guide

Más información sobre el libro

Over the last decade, the ARM architecture has become a dominant force globally, with over 2 billion ARM-based processors integrated into various products, from smartphones to automotive systems. A vast community of ARM developers, including software developers, system designers, and hardware engineers, has emerged, yet no book has specifically addressed their needs for developing systems and software for ARM-based platforms. This text fills that void by offering a comprehensive overview of ARM core operations from a developer's standpoint, with a strong focus on software. It guides readers in writing efficient ARM software in both C and assembly, while also covering code optimization. The book features example code that can be incorporated into commercial products or serve as templates for rapid software development. It discusses both ARM and Thumb instruction sets, Intel's XScale processors, and highlights differences among ARM architecture versions. Additionally, it covers DSP algorithm implementation, exception and interrupt handling, cache technologies surrounding ARM cores, and effective memory management techniques. A concluding chapter anticipates the future of the ARM architecture, particularly ARMv6, designed to enhance DSP and media processing capabilities. The author team brings extensive ARM software engineering experience and a deep understanding of developer needs, providing practical, executable code available
