Energy-Efficient UART Design on FPGA Using Dynamic Voltage Scaling for Green Communication in Industrial Sector

Abstract

In the present scheme of the world, the problem of shortage of power is seen across the world which can be a vulnerability to various communication securities. The scope of proposed research is that it is a step towards completing green communication technology concepts. In order to improve energy efficiency in communication networks, we designed UART using different nanometers of FPGA, which consumes the least amount of energy. This shortage is happening because of expanding of industries across the world and the rapid growth of the population. Therefore, to save the power for our upcoming generation, the globe is moving towards the concept and ideas of green communication and power-/energy-efficient gadget. In this work, a power-efficient universal asynchronous receiver transmitter (UART) is implemented on 28 nm Artix-7 field-programmable gate array (FPGA). The objective of this work is to reduce the power utilization of UART with the FPGA device in industries. To do this, the same authors have used voltage scaling techniques and compared the results with the existing FPGA works.

Design, refinement, and enhancement of FPGA-implemented UART circuitry

“…Lately, UART's reach has extended to numerous domains, including different environmental sensors and wireless communication modules. Notably, it finds use in fields like Field Programmable Gate Arrays (FPGAs), which serve as programmable logic devices [1]. Compared with traditional ASICs (Application-Specific Integrated Circuit), FPGA has higher flexibility in implementing design and has a wide range of application scenarios.…”
