RTE Configuration - Select Device
The Select Device view allows you to switch to another device and shows device properties.
Expand the list and select a device. Enter the name of a device using wildcards in the Search field
to narrow the list as you type.
You can select a new device and, when available, set the following properties:
- FPU: (only for devices with integrated FPU) tells the compiler whether floating point operations should be handled
via emulating floating point operations, or whether the floating point hardware instructions of the process should
be used instead (which will make the execution faster). If the hardware offers only single precision floating point operations,
then only double precision operation need emulation. If the hardware supports double precision, then the double precision instructions
can be generated and executed by the processor giving you the performance benefit for double precision computation.
Refer to Floating-point support for details.
The options listed in the tables below depend on the device in
use and are shown for devices with an implemented
FPU.
Floating Point Hardware options for Cortex-M7 with single precision FPU:
Options |
Description |
none |
Code generated does not use any VFP instructions. |
single precision |
Code generated uses VFP single precision
instructions. |
Floating Point Hardware options for Cortex-M7 with double precision FPU:
Options |
Description |
none |
Code generated does not use any VFP instructions. |
single precision |
Code generated uses VFP single precision
instructions. |
double precision |
Code generated uses VFP double precision
instructions. |
Floating Point Hardware options for Cortex-M4 with FPU:
Options |
Description |
none |
Code generated does not use any VFP instructions. |
single precision |
Code generated uses VFP single precision
instructions. |
- Endian: defines the method of accessing multi-byte data. Possible values are Litte-endinan and Big-endinan.
A selection is possible when the device supports both methods.
