FFT Burst mode - interrupt input

Honored Contributor II



my question is, if I can split the input for a burst FFT in multiple parts like with streaming?  

For example I have a 512 point FFT but my data comes in 64 point bocks. Can I just deassert sink_valid when I wait for the data and coninue later. 

I couldn't find anything in the documentation which wouldn't allow that, but neather that it is possible. For variable streaming however it is explicitly shown. 

I couldn' find information on this topic anywhere else. 


If the answer is no, is it possible for buffered burst then? 


Thank you for your help
