Abstract
A digital signal processing (DSP) block includes a Fast Fourier Transform (FFT) unit capable of performing an FFT operation. The FFT unit includes a first FFT engine capable of converting a signal between a time-domain and a frequency-domain and the first FFT engine is a fixed size FFT engine. The FFT unit also includes a second FFT engine communicatively coupled to the first FFT engine and the second FFT engine is a variable size FFT engine. The FFT unit also includes a scale/offset block communicatively coupled to the second FFT engine and the scale/offset block is capable of performing a multiplication operation, an addition operation, or a combination thereof on an output of the second FFT engine.
