Nonconventional Computer Arithmetic Circuits, Systems and Applications ©SHUTTERSTOCK.COM/AGSANDREW Feature Leonel Sousa, Senior Member, IEEE Abstract Arithmetic plays a major role in a computer's performance and efficiency. Building new computing platforms supported by the traditional binary arithmetic and silicon-based technologies to Digital Object Identifier 10.1109/MCAS.2020.3027425 Date of current version: 11 February 2021 6 IEEE CIRCUITS AND SYSTEMS MAGAZINE meet the requirements of today's applications is becoming increasingly more challenging, regardless whether we consider embedded devices or high-performance computers. As a result, a significant amount of research effort has been devoted to the study of nonconventional number systems to investigate more efficient arithmetic circuits and improved computer technologies to facilitate the development of computational units that can meet the requirements of applications in emergent 1531-636X/21©2021IEEE FIRST QUARTER 2021http://www.SHUTTERSTOCK.COM/AGSANDREW
