Preface About this book This book contains information that helps you with specific issues when developing code for the ARM ® family of Reduced Instruction Set Computing (RISC) processors. The chapters in this book, and the examples used, assume that you are using the latest release of RealView ® Compilation Tools (RVCT) to develop your code. Intended audience This book is written for all developers writing code for ARM architecture-based processors. It assumes that you are an experienced software developer, and that you are familiar with the ARM development tools described in RealView Compilation Tools Essentials Guide. Using this book This book is organized into the following chapters: Chapter 1 Introduction Read this chapter for an introduction to RVCT. Chapter 2 Embedded Software Development Read this chapter for information about how to develop embedded applications with RVCT. It describes the default RVCT behavior in the absence of a target system, and how to tailor the C library and image memory map to your target system. Chapter 3 Writing Position Independent Code and Data Read this chapter for information about how to write position independent code and data that makes use of the Procedure Call Standard for the ARM Architecture (AAPCS). Chapter 4 Interworking ARM and Thumb Read this chapter for information about how to change between ARM state and Thumb state when writing code for processors that implement the Thumb instruction set. Chapter 5 Mixing C, C++, and Assembly Language Read this chapter for information about how to write mixed C, C++, and ARM assembly language code. It also describes how to use the ARM inline and embedded assembler from C and C++. x Copyright © 2002-2007 ARM Limited. All rights reserved. ARM DUI 0203H Non-Confidential
Preface Chapter 6 Handling Processor Exceptions Read this chapter for information about how to handle the various types of exception supported by ARM processors other than Cortex-M1 or Cortex-M3 processors. Chapter 7 Handling Cortex-M3 Processor Exceptions Read this chapter for information about how to handle the various types of exception supported by Cortex-M3 processors. Chapter 8 Debug Communications Channel Read this chapter for a description of how to use the Debug Communications Channel (DCC). Appendix A Semihosting Read this appendix for information about the semihosting mechanism, that enables code running on an ARM target to use the I/O facilities on a host computer that is running an ARM debugger. This book assumes that the ARM software is installed in the default location. For example, on Windows this might be volume:\Program Files\ARM. This is assumed to be the location of install_directory when referring to path names. For example install_directory\Documentation\.... You might have to change this if you have installed your ARM software in a different location. Typographical conventions The following typographical conventions are used in this book: monospace monospace Denotes text that can be entered at the keyboard, such as commands, file and program names, and source code. Denotes a permitted abbreviation for a command or option. The underlined text can be entered instead of the full command or option name. monospace italic Denotes arguments to commands and functions where the argument is to be replaced by a specific value. monospace bold Denotes language keywords when used outside example code. italic Highlights important notes, introduces special terminology, denotes internal cross-references, and citations.
