Would it be easier? I just read some materials about mailbox core.[/b] --- Quote End --- Not really. A FiFo separates the to processors completely like a data cable. No need for additional synchronization very simple programming logic. Shared memory needs a semaphore (Mutex) to protect mutual accesses (e.g.for delivering and accepting messages, see appropriate literature). Altera does provide such a hardware Mutex fr the Avalon bus. You need to do appropriate software to work decently with same. -Michael [/b] --- Quote End --- Thank you for your reply. The Mailbox Core datasheet says that it owns an inner mutex, no need for user to add it artificially.
