Over 90% of mobiles phones sold over the last few years use ARM-based processors. Radically different from anything found in the current PC world, they provide huge number-crunching capabilities while consuming very little energy, making them perfect for the mobile world. However, newcomers to the field of embedded systems can be submerged by technical details and frightening component documentation. This book gently eases developers into the world of embedded ARM development by clearly explaining the different systems common to every ARM processor, and guides the user step by step to through a first embedded application. Professional Embedded ARM Development covers the basics of ARM embedded development, including a brief tour of the processors, the programming language used by the processor, and numerous programming examples.? History - A brief tour of the history of Acorn (ARM), what they used to use, why they created a new processor and where they stand today. Requirements - Some tools are required for developing on ARM systems, including boards, software and references, which I list extensively depending on the type of project the user wishes to embark upon. Assembly - Whatever language to program in, sooner or later it is converted to assembly language, and understanding it is crucial to debugging and low-level system programming C optimizations - Knowing assembly is important, but new projects will probably be written in C, and there are numerous optimizations that can be done to ensure fast code, getting the most out of an ARM processor Examples - No technical book can be complete without a Hello, World! Application, and I include a basic example, and slowly build on that example using either an ARM board, or a freeware application to simulate an ARM system This book gently eases developers into the world of embedded ARM development by clearly explaining the different systems common to every ARM processor, and guides the user step by step to his very first embedded application. ?
