ARMulator Basics

2.2 ARMulator components

ARMulator consists of a series of modules, implemented as Dynamic Link Libraries

(

.dll

files) for Windows, or as Shared Objects (

.so

files for Linux or Solaris,

.sl

files

for HPUX).

The main modules are:

• a model of the ARM processor core

• a model of the memory used by the processor.

There are alternative predefined modules for each of these parts. You can select the

combination of processor and memory model you want to use.

One of the predefined memory models,

mapfile

, allows you to specify a simulated

memory system in detail.

mapfile

allows you to specify narrow memories and wait

states (see Memory modelling with mapfiles on page 2-27).

In addition there are predefined modules which you can use to:

• model additional hardware, such as a coprocessor or peripherals

• model pre-installed software, such as a C library, semihosting SWI handler, or an

operating system

• extract debugging or benchmarking information (see Tracer on page 2-5 and

Profiler on page 2-12).

You can use different combinations of predefined modules and different memory maps

(see Configuring ARMulator on page 2-4).

You can write your own modules, or edit copies of the predefined ones, if the modules

provided do not meet your requirements. For example:

• to model a different peripheral, coprocessor, or operating system

• to model a different memory system

• to provide additional debugging or benchmarking information.

The source code of some modules is supplied. You can use these as examples to help

you write your own modules (see Chapter 3 Writing ARMulator models).
