A parallel biometric signal processor (100) and a method of controlling the parallel biometric signal processor are described. The processor includes amplifiers (110) configured to amplify a biometric signal based on an amplifying attribute and converters (120) configured to convert the amplified signal to a converted signal based on a converting attribute. The processor also includes preprocessors (130) configured to preprocess the converted signal based on a preprocessing attribute and feature extractors (140) configured to extract a set of biometric information from an output signal of the preprocessors.
