[MAX-10] NIOS-II -> what FPGA resources will be taken

Honored Contributor II

Hi All, 


I'm considering to use NIOS-II in the MAX-II device for arithmetic calculations.  


As far as I understand, there are several configurations for NIOS-II (economic, fast, etc).  


How can I know how many resources (Logic Elements, Memory Blocks, etc) each configuration requires?  


What's maximum size of Memory (RAM) might be attached to NIOS-II? Can it use an external DDR Memory?  


Actually I don't need any RTOS on the NIOS-II, just bare metal code will be ran there...  


Thank you!

Chapter 5 of the "nios ii gen2 processor reference guide (" gives some guidelines on expected resource utilisation. 


Yes, you can host DDR memory from a MAX 10 device. Have a read of an-730 ( It discusses it in detail.
