I want to make use of Neon coprcessor for my project, To enable neon, I have to follow these commands. I have to enter into privileged mode according to ARM reference manual. My questions are, Are those commands enough to enable neon? If privileged mode is required, then how to do it? I also referred the SWI-software interrupt and SWI handler, which excecute the commands in privileged mode but the complete procedure from user level is not clear.

For the actual instructions needed have you seen:. How to have that privilege?
