Mike,

If you place the reset address, of the second processor, at an offset in Flash, it won't be able to access any of the flash below that offset....provided both processors are in the same SOPC Builder system. You'd also have to use a Mutex (or several mutexes) for shared resources.

I believe there's a multi-processor tutorial dealing with this.
