I have a custom component with a memory mapped slave, I want to continuosly send audio input to it without using the nios cpu. Is this possible?

    Ofcourse. Create a component, with Avalon-MM master interface and connect your slave to it.

    That's the great thing about standard interfaces, if you want to replace a block you don't have to worry about reworking all the glue logic between it and the rest of your system.

    So instead of having Nios II write to your slave port, you could connect a DMA to it for example to move the data. What are you looking to use to provide the data to the audio component?
