On fixed-point processors, the dynamic range is [-1,1). In a radix-4 DIF FFT, the values computed in every butterfly stage can grow by [1]. Therefore the butterfly inputs must be scaled down to ...

Here the transformation related to the fast Fourier strategy mainly used in the field oriented well effective operations of the strategy elated to the scenario of the design oriented fashion in ...

The portability requirement of these systems is mainly responsible for the need of low power FFT architectures. In this paper, an efficient addressing scheme for radix-4 64 point FFT processor is ...

Here's how to implement an efficient radix-4 FFT, using the StarCore SC3000 as an ... including code structure and optimizations. The FFT output is verified against a floating-point MATLAB model, and ...
