FFT MegaCore Function Overview
======================================================================
The Altera(R) FFT MegaCore(R) function is a high performance,
highly-parameterizable FFT processor. The FFT MegaCore function
implements a Radix-2/4 decimation-in-frequency (DIF) FFT algorithm for
transform lengths of 2**m where 6 = m = 14, internally using a
block-floating-point architecture to maximize signal dynamic range
in the transform calculation.
