Implementation of Leading Zero Count (LZC) for Arithmetic and Logic Unit (ALU) Operations

Leading Zero Count (LZC) plays a crucial role in arithmetic and logic operations (ALU) within digital circuits, both sequential and combinational. LZC refers to the process of determining the number of consecutive leading zeros in a binary number. Both combinational and sequential LZC circuits find extensive usage in digital signal processing tasks, where quick and accurate determination of leading zeros is essential for various operations like normalization, filtering and feature extraction. Furthermore, they are integral components in hardware implementation of algorithms for data compression and encryption, contributing to enhanced efficiency and performance. The design principles, implementation strategies and applications of leading zero count in both combinational and sequential settings, highlighting their significance in modern digital systems. The LZC system is simulated and synthesized using Xilinx ISE tool and implemented on Artix-7 FPGA.
