Abstract:
A linear feedback shift register of the type comprising a plurality of linear feedback shift register (LFSR) flip flop circuits and a plurality of linear feedback shift register (LFSR) multiplexers alternately coupled together, where an input of each LFSR flip flop circuit is coupled to an output of an LFSR multiplexer, and where an output of each LFSR flip flop circuit may be provided to an input of an LFSR multiplexer, said linear feedback shift register comprising:a plurality of pre-load flip flop (PLFF) circuits and a plurality of pre-load flip flop (PLFF) multiplexers alternately coupled together, where an input of each PLFF flip flop circuit is coupled to an output of a PLFF multiplexer, and where an output of each PLFF flip flop circuit is coupled to an input of an LFSR multiplexer.
