    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.
