Arm provides CMSIS-Core-A files for the supported Arm Processors and for various compiler vendors. These files can be used when standard Arm processors should be used in a project. The table below lists the folder and device names of the Arm processors.

Folder	Processor	Description
".\Device\ARM\ARMCA5"	Cortex-A5	Contains Include and Source template files configured for the Cortex-A5 processor. The device name is ARMCA5 and the name of the Device Header File <device.h> is <ARMCA5.h>.
".\Device\ARM\ARMCA7"	Cortex-A7	Contains Include and Source template files configured for the Cortex-A7 processor. The device name is ARMCA7 and the name of the Device Header File <device.h> is <ARMCA7.h>.
".\Device\ARM\ARMCA9"	Cortex-A9	Contains Include and Source template files configured for the Cortex-A9 processor. The device name is ARMCA9 and the name of the Device Header File <device.h> is <ARMCA9.h>.

Note: CMSIS-Pack provides the #define CMSIS_header_file in RTE_Components.h which gives you access to the device.h file of a project. This allows you to generate generic software components that adjust to the device settings.
