user requirement is to build a system with four processors. there will be one processor which will communicate with other three but these three won't communicate with each other. the commucation should be done using mailboxes, whether it is a data or address. so if there is any reference design is available then it will be helpful for our design

If you find it useful, take a look at the FIFO example distributed here (http://www.evidence.eu.com/nios2/literature.asp).

Basically you can implement the same behavior in a more flexible way without becoming crazy with a lot of mailboxes and onchip memories...

There were also a previous topic on a similar issue, if I&#39;m right it was here (http://forum.niosforum.com/forum/index.php?showtopic=2798)

out of curiosity... what is your application about? how did hoy chose the partitiong of your application in four CPUs?
