Hi,
I am using beaglebone which has the processor TI Sitara AM335X. I want to make use of Neon coprcessor for my project, To enable neon, I have to follow these commands. But I can't access these registers ( especially FPEXC) in user mode. 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). Apart from enabling neon, do I need any other commands/procedures? Please help me to figure it out.
Thank you,
Rakshith Rao.
OpenSSL has NEON support built into it, perhaps you have already got it running properly, which is a bit sad if it is not fast enough for you.
