Provides architectures of approximate arithmetic circuits optimized for FPGA-based systems. This book presents various novel architectures for FPGA-optimized accurate and approximate operators, their detailed accuracy and performance analysis, various techniques to model the behavior of approximate operators, and thorough application-level analysis to evaluate the impact of approximations on the final output quality and performance metrics. As multiplication is one of the most commonly used and computationally expensive operations in various error-resilient applications such as digital signal and image processing and machine learning algorithms, this book particularly focuses on this operation. The book starts by elaborating on the various sources of error resilience and opportunities available for approximations on various layers of the computation stack. It then provides a detailed description of the state-of-the-art approximate computing-related works and highlights their limitations.

This bestselling guide can teach anyone the basics of iPad. Fully updated for the newest Apple releases, iPad For Seniors For Dummies, 2023-2024 Edition features all the helpful basics you need to know―and beyond! You’ll find info on security, using iCloud, setting up an Apple ID (and what that even means, anyway), using the App Store, connecting to Wi-Fi, watching movies and TV, playing games, and staying organized. And it’s all in easy-to-read, larger print! Because you bought this book (or are thinking about buying it), you’ve probably already made the decision to buy an iPad. The iPad is designed to be easy to use, but you can still spend hours exploring the preinstalled apps, configuring settings, and learning out how to sync the device to your computer or through iCloud. I’ve invested those hours so that you don’t have to — and I’ve added advice and tips for getting the most from your iPad.

This book presents the applications of non-volatile CBRAM/MIM switching technology for electronically reconfigurable passive RF and microwave devices, together with theory and methods for application in rewritable chipless RFID tags. Conductive Bridging Random Access Memory (CBRAM) is a renowned and commercially used non-volatile memory concept. Having evolved over the past few decades, it is currently identified as an efficient non-volatile RF switching technology. This book presents recent research on this topic, focusing on the development of a new generation of low-cost non-volatile RF switches and their applications, demonstrating both high performance and flexibility of implementation. It includes the experimental realization of various prototypes of RF and microwave devices utilizing this technology, along with relevant analysis of mathematical and electrical models, and detailed discussions of future aspects. All devices presented are compatible with mass industrial production at an economically efficient budget through optimized fabrication steps, without the requirement of sophisticated “clean room” processes among them.
