Fuente: Wipo "digitalization" A data stream processing device including a first tapped delay line which outputs data values received via a first data input on N first taps, wherein N is two or more; a second tapped data delay line which outputs data values received via a second data input on N second taps; a first processing unit including N first delayed data inputs and which generates a first data output based on the N first delayed data inputs; a second processing unit including N second delayed data inputs and which generates a second data output based on the N second delayed data inputs; and control circuitry including a mode selection input, and which is coupled to in response to the mode selection input receiving a signal indicating a first mode, simultaneously couple each of the first taps to a respective one of the first delayed data inputs and couple each of the second taps to a respective one of the second delayed data inputs, and in response to the mode select input not receiving a signal indicating the first mode, simultaneously couple one of the first taps to one of the second delayed data inputs and couple one of the second taps to one of the first data inputs.
