In this article we present an implementation of the FFT on the StarCore SC3000 DSP core. We use a radix-4 decimation in frequency (DIF) variant of the FFT and optimize our code to take advantage of ...

Various architectures exist for this. The pipeline FFT processor is based on the Radix-2 Single-path Delay Feedback (R2SDF) architecture. In the FFT approach described above, delay between each ...

Figure 13–52. Zoom FFT spectra: (a) input spectrum; (b) processing scheme; (c) downconverted spectrum; (d) filtered and decimated spectrum. We could collect many time samples and perform a large-size ...

Here's how to implement an efficient radix-4 FFT, using the StarCore SC3000 as an example. The Fast Fourier Transform (FFT) is a widely used algorithm that computes the Discrete Fourier Transform (DFT ...
