The Design of a Reconfigurable Continuous-Flow Mixed-Radix FFT Processor

Abstract:

The design of a highly configurable continuous flow mixed-radix (CFMR) 
Fast Fourier Transform (FFT) processor is presented.  It computes 
fixed-point complex FFTs and inverse FFTs (IFFTs), and utilizes a 
flexible addressing scheme to enable runtime configuration of the FFT 
length from 16-points to 4096-points.  A configurable block floating 
point (BFP) unit increases numerical performance.  Compared to a 
floating point Matlab FFT function, the accuracy of the proposed 
architecture is 80 dB for a 64-point FFT and 74 dB for a 1024-point 
FFT with random complex input data.
