FFT Reference Design

This free design demonstrates the usage of a fixed-point OptNgn FFT library element on an Opal Kelly XEM3010 module.

The reference design processes an input data stream of pairs of real numbers, representing a stream of complex numbers, in a C++ program running on a PC, ships that stream, over the Opal Kelly USB link, in a frame-by-frame way, to the XEM3010 board, processes each frame through the streaming OptNgn FFT residing on the target FPGA, and then ships the transformed frames back to the PC.
