Against the backdrop of increasingly serious climate change, researchers are attempting to extend macroscale carbon reduction research to smaller scales. With the rapid development and widespread application of electric vehicles(EVs), an effective approach for carbon reduction based on EVs has the potential to be developed. To coordinate and manage the EV platform in diverse application scenarios, the concept of an on-board nanogrid(OBNG), in which a nanogrid is combined with the EV, is proposed and defined, and the characteristics summarized. A configuration that includes a physical layer with the on-board hardware system;an information layer for logical control, energy management, and communication coordination;and an application layer that can cope with different working environments is proposed. A detailed introduction to the basic architecture and management mode of each layer is provided along with information concerning the relevant technologies for coordinated operation. New ideas and approaches to improve the existing performance are proposed, and finally, combined with a background of smart and low-carbon cities, major application scenarios are envisioned.

Realization of Complete Boolean Logic and Combinational Logic Functionalities on A Memristor-Based Universal Logic Circuit

引用

Chinese Journal of Electronics 2024年

作者： Xiaojuan LIAN Chuanyang SUN Zeheng TAO Xiang wan Xiaoyan LIU Zhikuang cai Lei wanG The College of Integrated Circuit Science and Engineering Nanjing University of Posts and Telecommunications

Memristors are a promising solution for building an advanced computing system due to their excellent characteristics, including small energy consumption, high integration density, fast write/read speed, great endurance and so on. In this work, we firstly design three basis logic XNOR1, XNOR2 and XOR gates by virtue of memristor ratioed logic(MRL), and further construct 1-bit numerical comparators, 2-bit numerical comparators and full adder 1 based on the above XNOR1, XNOR2 and XOR gates. Furthermore, we propose and design a universal logic circuit that can realize four different kinds of logic functions(AND, OR, XOR, XNOR) at the same time. Subsequently, a full adder 2 is built using XOR function of this universal logic circuit. Compared with the traditional CMOS circuits, the universal logic circuit designed in this work exhibits several merits such as fewer components, less power, and lower delay. This work demonstrates that memristors can be used as a potential solution for building a novel computing architecture.
