Linear Feedback Shift Register and its Applications in Digital System Design

In digital system design, the Linear Feedback Shift Register (LFSR) is the queen of logic functions, and the design engineers can use LFSR in both hardware (HW) or software (SW) implementation. In this paper, LFSR will be discussed in its HW implementation via Hardware description language. In addition, the application of LFSR in of pseudorandom number generator (PRNG), direct sequence spread spectrum (DSSS), cyclic redundancy check (CRC) is also given.
