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.
Anyway I think what you should do is check to see if it is all working properly so I did a Google search with 'beaglebone openssl speed' and restricted the search to the last year and got for instance the following along with a number of other responses
ssl - Beaglebone Black OpenSSl crypto acceleration - Super User
It says how about how long the tests should take, if they take much longer there is some problem with setting it up.
