Custom instructions ??

Hi, 

i am new to the NIOSII and i never worked with custom instructions. How do i have to do that? Can custom instructions be a part or "link" to a VHDL-Code?  Thanks Paddy

Custom instructions are written in VHDL - so can import signals from any other VHDL block. 

Loosely each instruction has two 32bit inputs and one 32bit output, which can be any bits the VHDL needs for any purpose.

Ok, that sounds good! I will try this. 

Thank you very much, Paddy
