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

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 (https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/hb/nios2/n2cpu-nii5v1gen2...)" gives some guidelines on expected resource utilisation. 

 

Yes, you can host DDR memory from a MAX 10 device. Have a read of an-730 (https://www.altera.com/en_us/pdfs/literature/an/an730.pdf). It discusses it in detail. 

 

Cheers, 

Alex
