ARMulator Reference

4.6 Events

ARMulator has a mechanism for broadcasting and handling events. These events

consist of an event number and a pair of words. The number identifies the event. The

details depends on the event.

The core ARMulator generates some example events, defined in

armdefs.h

. They are

divided into three groups:

• events from the ARM processor core, listed in Table 4-2 on page 4-30

• events from the MMU and cache (not on StrongARM

-110), listed in Table 4-1

• events from the prefetch unit (ARM8

™

-based processors only), listed in Table 4-3

on page 4-30

• configuration change events, listed in Table 4-5 on page 4-31.

These events can be logged in the trace file if tracing is enabled, and trace events is

turned on. Additional modules can provide new event types that will be handled in the

same way. User defined events must have values between

UserEvent_Base

(

0x100000

)

and

UserEvent_Top

(

0x1FFFFF

You can catch events by installing an event handler (see Event handler on page 4-37).

You can raise an event by calling

ARMulif_RaiseEvent()

(see ARMulif_RaiseEvent on

page 4-32).
