I've done it two ways.

Easiest is to just connect both processors to the same memory using the SOPC Builder patch panel. (in my case sdram)

The other way that works faster/better in my system is I added a small onchip sram block and made it dual ported and connected each of two processors to a different port. Then I just developed my own little protocol for them to send commands and data to each other through this "mailbox" ram.

Hope this helps.
