Abstract
In one embodiment, a shift register is provided. The LFSR includes a plurality of processing stages coupled in series, each configured to implement N taps of the LFSR. N single-tap circuits are coupled together in series and arranged to implement the last N taps of the LFSR. Each coefficient(s) of a feedback polynomial of the LFSR is implemented by one of the taps of the plurality of processing stages or the N single-tap circuits. A feedback generation circuit is configured to provide, for each of the plurality of processing stages, a respective feedback signal as a function of polynomial coefficients implemented by the processing stage and output from one or more of the N single tap circuits.
