FPGA Implementation of Binary Counter using Bidirectional Gate: A Study
Main Article Content
Abstract
Binary counters are fundamental building blocks in digital systems, widely used in timing, control, and counting applications. The design and implementation of energy-efficient, high-speed, and low-area binary counters have gained increasing importance in the field of digital electronics and VLSI systems. This paper presents an FPGA-based implementation of a synchronous binary counter using bidirectional logic gates. The utilization of bidirectional gates helps to reduce the number of logic transitions, resulting in lower power consumption and increased speed.
The study involves the design synchronous binary counter using VHDL/Verilog, integrating bidirectional gates to optimize logic. The implementation is carried out on a Xilinx FPGA platform, and synthesis is performed using Vivado. The performance metrics such as area utilization, timing delay, and power consumption are analyzed and compared with traditional counter architectures. Experimental results demonstrate that the proposed design offers a noticeable improvement in power efficiency and delay reduction without compromising on area or reliability. This study paves the way for the adoption of bidirectional logic in various sequential circuits, highlighting its suitability for low-power and high-performance applications in embedded and real-time systems.
