Access On-Chip memory from NIOS and custom logic

Thanks for the hints. I am looking into your suggestions once at a time.

1) You could get the fpga hardware initialise to load your memory block - then you only need a single read interface to the memory block.

I am assuming you refer to the Memory Initialization File (.mif) ?

I like the idea b/c I could create this file with a script in Matlab. What happens when a reset is performed, will the memory blocks be initialized again ?

Eventually there will be a NIOS II system for state machine purposes etc. regardless of how the control dedicated memory will be loaded. In case I am using parts of the On-Chip memory with the NIOS II, I assume I have to be very careful with the address range I specify b/c otherwise NIOS II will override some of my memory.

The dedicated memory should be configured as ROM, it is very important that the stored values remain unchanged.

Anything else I have to watch out for if I go with this approach?
