Hi, I would like to implement an RFNoC FFT that can work for lengths > 1024. Here's what I think I know:
- Current size for CE-to-CE packets is restricted to 8000 bytes (2000 samples) - Current RFNoC FFT size is tied to packet size and thus 1024 is the max FFT size that can fit in a packet After reviewing previous posts and Xilinx FFT IP core documentation, it seems that all I need to do is add packet resize logic at the input and output of the block. Specifically, I am thinking of using "packet_resizer.v" at both input and output (but only modifying tuser in the output instance). Questions - Is this a good approach? - Anything special that I need to take care of? - Does the selection of FFT architecture (pipelined, radix-4, etc) have any relevance concerning this issue? Rob
