Writing ARMulator models

3.1.2 Supplied models

ARMulator is supplied with source code for the following groups of models:

• Basic models

• Peripheral models on page 3-4

Basic models

tracer.c

The tracer module can trace instruction execution and events from within

ARMulator (see Tracer on page 4-57). You can link your own tracing

code onto the tracer module.

profiler.c

The profiler module provides the profiling function (see Profiler on

page 2-12). This includes basic instruction sampling and more advanced

use, such as profiling cache misses. It does this by providing an

UnkRDIInfoHandler

that handles the profiling requests from the debugger

(see Unknown RDI information handler on page 4-35).

pagetab.c

On reset, this module sets up cache, PU or MMU and associated

pagetables inside ARMulator (see Pagetable module on page 2-19).

stackuse.c

If enabled this model tracks the stack size. Stack usage is reported in the

ARMulator memory statistics. You can set the stack upper and lower

bounds in the

peripherals.ami

file (see Stack tracker on page 2-36).

nothing.c

This model does nothing. You can use this in the

peripherals.ami

file to

disable models (see Configuring ARMulator to disable a model on

page 3-10).

semihost.c

This model provides the semihosting SWIs described in Chapter 5

Semihosting.

dcc.c

This is a model of a Debug Communications Channel (DCC).

mapfile.c

This model allows you to specify the characteristics of a memory system.

See Map files on page 4-59 for further information.

flatmem.c

flatmem

models a zero-wait state memory system. See Default memory

model on page 2-26 for further information.
