Honored ContributorHardware -> Nios II big data transfer
Hello, I'm having questions about how to send a big data buffer from my VHDL Hardware component to my Nios II. The problem with this buffer is that its size can vary from 90bits to 2000bit...

Honored ContributorYou need to write into memory the Nios can read, obvious options:
1) Add an Avalon master interface to your vhdl component and write directly to any Avalon slave. 2) Add an Avalon slave interface and use DMA (or direct access from the nios cpu). 3) Dual port an internal memory block between your vhdl and the nios cpu.
