4.14.1 Predefined tags
Before reading
.ami files, ARMulator creates several tags itself, based on the settings
you give to the debugger. These are given in Table 4-7. Preprocessing directives in
.ami
files use these tags to control the configuration.
4.14.2 Processors
The processors region is a child ToolConf database (see ToolConf on page 4-68). It has
a full list of processors supported by the ARMulator. This list is the basis of the list of
processors in AXD, and the list of accepted arguments for the
-processor option of
armsd .
You can add a variant processor to this list, for example to include a particular memory
model in the definition. See
install_directory\Bin\example1.ami for examples.
Default specifies the processor to use if no other processor is specified. Each other entry
in the
Processors region is the name of a processor.
Example 4-2 on page 4-65 declares two processors, TRACED_ARM10 and
PROFILED_ARM7. In this example,
MCCFG is the ratio of the clock frequency on the
processor to the clock frequency on the external bus.
Table 4-7 Tags predefined by ARMulator
Tag Description
CPUSpeed Set to the speed set in the configuration window of AXD, or in the
-clock command line option for armsd . For example,
CPUSpeed=30MHz .
FCLK Set to the same value as CPUSpeed , if that value is not zero. Not set
if
CPUSpeed is zero.
MCLK Set to the same value as FCLK for uncached cores.
Set to
FCLK / MCCFG for cached cores.
ByteSex Set to L or B if a bytesex is specified from the debugger. Not set
otherwise.
FPE Set to True or False from the debugger.
