High-Speed Counter With Novel LFSR State Extension

Project Code :TVMAFE571

Objective

The main objective of this project is to implement 64-bit counter based on LFSR

Abstract

This paper presents a high-speed counter architecture associated with novel LFSR state extension. By employing the proposed state extension, an m-bit LFSR counter with ð2m 1Þ states is modified to cover 2m states without degrading the counting rate. Based on the property that only the low-order bits are frequently switched, the proposed counter consists of two sub-counters to achieve a high counting rate and reduce the hardware complexity needed to convert an LFSR state into a binary state. The low-order sub-counter is implemented with the proposed LFSR counter, and the high-order sub-counter is designed by employing the conventional synchronous binary counter. In addition, the implemented counter takes into account the speed degradation caused by the large fan-out of the highorder sub-counter. The proposed counter designed using Verilog HDL in Xilinx ISE/Vivado tools.
