1. A processor, comprising:
a hardware decompressor configured to pad a non-equidistant data set, which is data received at irregular time intervals, with one or more of a predefined value, wherein the non-equidistance data set is padded to a bit length that is to a power of two, and the data is radar or optical sensor data; and
a Fourier transform engine configured to receive the padded non-equidistant data set directly and continuously per data set from the hardware decompressor, and to FFT process the received padded non-equidistant data set.
