1.2 GS/sec floating point FFT

1.2 Gigasample/sec IEEE single precision floating point FFT.
400 MHz in XCV4SX55-11

	32 to 2048 point complex in, complex out
	IEEE single precision floating point in and out
	30-35 bit mantissa internal
	3 complete 400MHz FFT processors in parallel
	2D-FFT in two passes
	Equivalent to 66 GFLOPs
	This design is described in the paper Hybrid Floating Point Technique Yields 1.2 Gigasample Per Second 32 to 2048 point Floating Point FFT in a single FPGA and in the Xilinx DSP magazine article Supercharge Your DSP with Ultra-Fast Floating-Point FFTs
