Can de0-nano work with high speed ADC (such as AD9283)?

Dear Community, I'm working in a wind meter based in DE0-NANO development board and NIOS II. Here's a basic block diagram of project: ultrasonic signal 1 (total length of 1000 us) -> ad conve...

The DE0-nano will work fine with this ADC.

Your attempts to use the NIOS II to process the data in real-time might be futile however.

If you only need to process pulse data, then you should write some HDL to "trigger", eg., then the input is above some thresholds, write a snapshot of the data to RAM, and then process that snapshot with the NIOS II. If you have to process the data continuously, then you will need to write some HDL to do that.

Go and read about the SignalTap II logic analyzer. Capture a trace of samples from the ADC using the logic analyzer. Then think a little more about what you need to do.

There are SignalTap II logic analyzer trace examples for the DE0-nano here ...
