There is no single correct or "best" way to implement communications between the ARM core and the two PRUs. This is a standard problem in all multiple core machines, and you will find a lot of material with a quick Google search. Depending on your application you may want to use things like mailbox registers, lockless queues, interrupt signaling, req/ack handshakes, etc. -- Charles Steinkuehler [email protected] -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
