Processor Components
Table 4-3 provides a description of the configuration parameters for each ARMCortexA15xnCT
component processor. These parameters are set individually for each processor you have in your
system.

Parameter Description Type
Allowed
Value
Default
Value
CFGEND Initialize to BE8 endianness. boolean true or false false

Initialize to disable access to some CP15
registers.
Thumb exception enable. The default
has exceptions including reset handled
in ARM state.
boolean true or false false
boolean true or false false
VINITHI Initialize with high vectors enabled. boolean true or false false
ase-present a
Set whether CT model has been built
with NEON support.
boolean true or false true
semihosting-cmd_line
Command line available to semihosting
SVC calls.
string
no limit
except
memory
[empty
string]
semihosting-debug b
Enable debug output of semihosting
SVC calls.
boolean true or false false
semihosting-enable Enable semihosting SVC traps. boolean true or false true
semihosting-ARM_SVC ARM SVC number for semihosting. integer 0x000000 -
0xFFFFFF
0x123456
semihosting-Thumb_SVC Thumb SVC number for semihosting. integer 0x00 - 0xFF 0xAB
semihosting-heap_base Virtual address of heap base. integer 0x00000000 -
0xFFFFFFFF
semihosting-heap_limit Virtual address of top of heap. integer 0x00000000 -
0xFFFFFFFF
0x0
0x0F000000
semihosting-stack_base
Virtual address of base of descending
stack.
integer 0x00000000 -
0xFFFFFFFF
0x10000000
semihosting-stack_limit Virtual address of stack limit. integer 0x00000000 -
0xFFFFFFFF
0x0F000000
vfp-enable_at_reset c
vfp-present a
Enable coprocessor access and VFP at
reset.
Set whether CT model has been built
with VFP support.
boolean true or false false
boolean true or false true
a. The ase-present and vfp-present parameters configure the synthesis options for the Cortex-A15 model. The options are:
vfp present and ase present
NEON and VFPv3-D32 supported.
vfp present and ase not present
VFPv3-D16 supported.
vfp not present and ase present
Illegal. Forces vfp-present to true so model has NEON and VFPv3-D32 support.
vfp not present and ase not present
Model has neither NEON nor VFPv3-D32 support.
b. Currently ignored.
