Writing ARMulator models

3.2.3 Initialization, finalization, and state macros

To help you to write new ARMulator models, the following six macros are provided in

minperip.h

•

BEGIN_INIT()

•

END_INIT()

•

BEGIN_EXIT()

•

END_EXIT()

•

BEGIN_STATE_DECL()

•

END_STATE_DECL()

Use the following to define an initialization function for your model:

BEGIN_INIT(your_model)

{

* (your initialization code here)

}

END_INIT(your_model)

Use the following to define a finalization function for your model:

BEGIN_EXIT(your_model)

{

* (your finalization code here)

}

END_EXIT(your_model)

The

BEGIN_INIT()

macro defines a structure to hold any private data used by your model,

and the

END_EXIT()

macro frees it. Declare the data structure using:

BEGIN_STATE_DECL(your_model)

* (your private data here)

END_STATE_DECL(your_model)

3.2.4 Registering your model

Your model must register itself by calling

registerPeripFunc()

. This enables

ARMulator to call your model with accesses to memory locations that belong to your

model. See ARMul_BusRegisterPeripFunc on page 4-41.
