Good afternoon!
For the C6678 was written 2 projects, the first I load on the core 0, the second - at the cores 1-5.
The core 1 is waiting for a new data in the shared memory area (they appear on average once every 15 microseconds), when new data core 1 sends Notifies to cores 2-5.
(That is, the second project is designed so that, depending on the number of the cores starts different Tasks).
Cores 2-5 process the data, copy them to DDR3 and send Notify on the core 0. On receipt Notify Core 0 stores the data in the flash memory.
Everything works perfectly!
Then 2 more projects have been created for the cores 6 and 7. It is no processing is performed. But they have already started the BIOS, as well as connected to the IPC.
Now cores 1-5 does not have time to process the data in 15 microseconds.
I tried to remove Notify in projects for cores 6 and 7 - everything works as before, good!
Everything works as before - tried to remove the CPI cores 6 and 7! But I need to synchronize the cores to each other ..
Anyone can tell you the reason for this slowing of the processor? How can it be solved?
Thank you!
