Abstract

This linear feedback shift register (LFSR) circuit having systolic architecture comprises N cells (C1 to CN) each of which includes an upstream register (e.g. RGE1l ), two operators (e.g. OP1 and OC1l ), and a downstream register (e.g. RGS1). The upstream and downstream registers of each cell are serial shift registers, and their total content is equal to the total number of bits constituting each digital sample processed by the circuit.
