one processor access multi ochip memory??

To my understanding, the mutex is used when there are more than one processors trying to access to a single resource eg. onchip memory. The mutex is like "the rights to access a peripheral". Hence whichever processor has aquired the mutex can access your memory and the other processor cannot... or should I say should not.

If there are multiple memories connected to a single processor in an sopc system, you can access them in many ways.

> If you want your processor to manage them and access them for its data memory, stack or heap, then you can control that using the "system properties" dialog box in the NIOS II IDE for that project.

> If you want to manage the memory manually like using the memory to store some data, you can do something like use pointers and map out variables and structures by urself.

All depends on what you want to do...

Hope this helps...
