Abstract
An apparatus includes front-end circuitry to receive radar wave signals and a fast fourier transforms (FFT) signal processor. The FFT signal processor includes multiplication logic circuitry and other logic circuitry. The FFT signal processor derives doppler information from the radar wave signals by operating on a digital stream of input data representing the radar wave signals including using the multiplication logic circuitry to perform multiplication operations on first data in the digital stream while the first data is represented in a signed magnitude form, and using the other logic circuitry to perform other mathematical operations on second data in the digital stream while the second data is represented in a two's complement form.
