Epiphany Timers Synchronization

Postby omar » Wed Apr 08, 2015 12:18 pm

Hi,
I wonder how to synchronize the timers in all cores? for example i want to start e_ctimer0 in all cores at the same time the purpose of this is to get the travel time for read and write transactions.

I don't know if you can guarantee such a fine granularity.
Barriers might be good enough for your purposes, otherwise it should be possible to trigger an interrupt simultaneously on all cores.
