Hi,
I'm designing a LFSR (8bit) (linear feedback shift reg.) with xnor feedback. There are 2 topologies: one-to-many(internal) and many to one(external). I was wondering if anyone could elaborate on the pros and cons of the two topologies?
For instance, I know that the one-to-many topology when compared to the many-to-one would reduce the propogation delay through xnor gates...but is there also a disadvantage to the internal LFSR topology?
