Design Space Exploration Of Emerging Technologies For Energy Efficiency

As the demand for denser and faster electronics is growing, semiconductor industry has responded by aggressively scaling transistor sizes to several nanometers. Nano-scale devices provide higher density circuits while imposing crucial power, thermal and reliability problems to the system. As wire width continue to shrink, copper interconnects in high-performance systems will suffer from significant increase in resistivity due to surface roughness and grain boundary scattering resulting in electromigration issues. Furthermore, as technology scaling following Moore’s law is reaching its limits, 3D integration is a novel, promising and fast-emerging technology. 3D integration provides several advantages over 2D ICs by enabling, higher functionality, small form factor and heterogeneous implementation.The work presented in the HDR manuscript addresses the challenges of designing reliable and energy efficient circuits and systems for emerging technologies. It covers:-modeling and simulation for understanding the physical, electrical and thermal behavior on 3D integrated circuits.-physical design methods for power and signal integrity of 3D integrated circuits.-energy efficiency exploration on circuits based on carbon nanotube (CNT) interconnects

Internet of robotic things : converging sensing/actuating, hypoconnectivity, artificial intelligence and IoT Platforms

The Internet of Things (IoT) concept is evolving rapidly and influencing newdevelopments in various application domains, such as the Internet of MobileThings (IoMT), Autonomous Internet of Things (A-IoT), Autonomous Systemof Things (ASoT), Internet of Autonomous Things (IoAT), Internetof Things Clouds (IoT-C) and the Internet of Robotic Things (IoRT) etc.that are progressing/advancing by using IoT technology. The IoT influencerepresents new development and deployment challenges in different areassuch as seamless platform integration, context based cognitive network integration,new mobile sensor/actuator network paradigms, things identification(addressing, naming in IoT) and dynamic things discoverability and manyothers. The IoRT represents new convergence challenges and their need to be addressed, in one side the programmability and the communication ofmultiple heterogeneous mobile/autonomous/robotic things for cooperating,their coordination, configuration, exchange of information, security, safetyand protection. Developments in IoT heterogeneous parallel processing/communication and dynamic systems based on parallelism and concurrencyrequire new ideas for integrating the intelligent “devices”, collaborativerobots (COBOTS), into IoT applications. Dynamic maintainability, selfhealing,self-repair of resources, changing resource state, (re-) configurationand context based IoT systems for service implementation and integrationwith IoT network service composition are of paramount importance whennew “cognitive devices” are becoming active participants in IoT applications.This chapter aims to be an overview of the IoRT concept, technologies,architectures and applications and to provide a comprehensive coverage offuture challenges, developments and applications
