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

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 b
Enable coprocessor access and VFP
at reset.
Set whether the model has VFP
support.
boolean true/false false
boolean true/false true
dcache-size Set D-cache size in bytes. integer 4KB, 8KB,
16KB, 32KB,
or 64KB
icache-size Set I-cache size in bytes. integer 4KB, 8KB,
16KB, 32KB,
or 64KB
0x8000
0x8000
a. The ase-present and vfp-present parameters configure the synthesis options for the Cortex-A5 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.
c. This is a model specific behavior with no hardware equivalent.
