Glossary

ADS

See ARM Developer Suite.

ANSI

American National Standards Institute. An organization that specifies

standards for, among other things, computer software.

Angel

Angel is a debug monitor that enables you to develop and debug

applications running on ARM-based hardware. Angel can debug applications

running in either ARM state or Thumb state.

ARM Developer Suite

A suite of applications, together with supporting documentation and

examples, that enable you to write and debug applications for the ARM

family of RISC processors.

ARM eXtended Debugger

The ARM eXtended Debugger (AXD) is the latest debugger software from

ARM that enables you to make use of a debug agent in order to examine

and control the execution of software running on a debug target. AXD is

supplied in both Windows and UNIX versions.

ARMulator

ARMulator is an instruction set simulator. It is a collection of modules that

simulate the instruction sets and architecture of various ARM processors.

armsd

The ARM Symbolic Debugger (armsd) is an interactive source-level

debugger providing high-level debugging support for languages such as C,

and low-level support for assembly language. It is a command-line debugger

that runs on all supported platforms.

ATPCS

ARM and Thumb Procedure Call Standard defines how registers and the

stack will be used for subroutine calls.

AXD

See ARM eXtended Debugger.

Big-Endian

Memory organization where the least significant byte of a word is at a higher

address than the most significant byte.

Canonical Frame Address

In DWARF 2, this is an address on the stack specifying where the call frame

of an interrupted function is located.

CFA

See Canonical Frame Address.

Coprocessor

An additional processor which is used for certain operations. Usually used

for floating-point math calculations, signal processing, or memory

management.

Double word

A 64-bit unit of information. Contents are taken as being an unsigned integer

unless otherwise stated.

DWARF

Debug With Arbitrary Record Format

EC++

A variant of C++ designed to be used for embedded applications.

ELF

Executable Linkable Format

Execution view

The address of regions and sections after the image has been loaded into

memory and started execution.

Flash memory

Non-volatile memory that is often used to hold application code.

Halfword

A 16-bit unit of information. Contents are taken as being an unsigned integer

unless otherwise stated.

Heap

The portion of computer memory that can be used for creating new

variables.

ICE

In Circuit Emulator.

IDE

Integrated Development Environment (Code Warrior).

Image

An executable file which has been loaded onto a processor for execution.

A binary execution file loaded onto a processor and given a thread of

execution. An image may have multiple threads. An image is related to the

processor on which its default thread runs.

Inline

Functions that are repeated in code each time they are used rather than

having a common subroutine. Assembler code placed within a C or C++

program.
