Only this very incomplete document exists to my knowledge: https://www.intel.com/content/www/us/en/programmable/documentation/hco1421694900164.html#dmi14141560...
It does not describe the packet construction for communication. I actually think it is a wrong document -- it is for the cyclone5 version that doesnt use this strange Avalon interface. Although a generated testbench gives a structure for the interface, I have no idea how to use this AvalonST (itself poorly documented) system to start the NCO. Where is the example code??
Am I missing something? Is there an easier way to communicated with this NCO component?
As I understand it, this is the only NCO IP user guide available. Sorry for the inconvenience if there is any confusion. Please allow me some time to further look into this and get back to you. Please ping me if you do not hear back from me by end of the week.
Really sorry for the delay. I might have overlooked this. For your information, Avalon ST standard is a generally used interface in our IP which defines data transfer from a source interface to a sink interface. For further details of the interface specs, you may refer to the following Avalon Interface Specs doc:
Sorry for the inconvenience.
