This book serves as a foundation to the field of HCI, equipping readers with the necessary knowledge and skills to engage in this field. Human‑Computer Interaction (HCI) is a multidisciplinary field exhibiting increasing significance in the modern world, shaping our interactions with technology and transforming our daily lives. HCI plays a critical role in bridging the gap between human capabilities and technological breakthroughs. As technology becomes progressively intertwined with our daily lives, it plays a significant role in enhancing human interaction with advanced information technologies. This book serves as a foundation for the field of HCI. It covers the historical background, contributing disciplines, essential concepts and theories within the domain. This book also delves into human functionalities and characteristics relevant to interaction, including sensory perception, attention and memory, language and communication, emotions, decision‑making, as well as mental models, human error, and human actions. Moving forward to the realization of interaction, traditional techniques provide users with foundational methods for engaging with computers and digital systems. These techniques have adapted and endured, shaping user experiences and catering to evolving technological landscapes. Keyboard input, a versatile mainstay, allows efficient text entry and commands, especially valuable for programming and command‑line interfaces (CLIs). The mouse, in tandem with Graphical User Interfaces (GUIs), revolutionized navigation through pointing, clicking, and dragging. Touch input, introduced with touchscreen devices, offers a direct and intuitive interaction with content. Menu‑based interfaces create structured hierarchies for accessing functions and information, while CLIs remain a powerful choice for experts who value precision.

This book discusses larger signal amplifiers (denoted as PA). Large signal amplifiers are dealing with signals whose magnitude is such that the operation of the active element can no longer be considered linear. They are usually designed to get as much power gain and efficiency as possible. That is why they are often called power amplifiers. In this book, two implementations of PA are considered. First, it is of interest to obtain large signals (current or voltage) at the output of a cascade of direct coupled amplifiers. In this case, linearity, frequency response, and speed are the most important requirements. Second are real power amplifiers where the power delivered to the load is of primary interest. Of course, efficiency, linearity, and high frequency response are of interest, too. A very special attention is paid to modern power electronic components such as Power BJT, VDMOS, IGBT, SiC MOS, and GaN HEMT. DC and switching properties of all these devices are studied in much detail. This book also includes a set of appendices which cover: solved problems, SPICE simulation results for selected set of circuits, and a short review of microelectronic technology process.

This textbook unlocks modern computer organizations' secrets, with real-world examples from RISC-V, ARM, and Intel-based computer systems. The guide provides a comprehensive yet accessible explanation of fundamental principles and components and serves as a gateway to mastering the interplay between hardware and software. It demystifies complex concepts and provides clear explanations and practical insights into their roles in computing systems. Our journey begins with exploring memory-mapped I/O, where we unravel the mechanisms by which the CPU communicates with peripherals through memory addresses. From there, we venture into the realm of interrupts, examining how various architectures handle asynchronous events and prioritize tasks efficiently. Real-world examples from RISC-V, ARM, and Intel-based systems illuminate these concepts, providing practical insights into their implementation and significance. Chapter 3 delves into the intricacies of Direct Memory Access (DMA), shedding light on the controllers responsible for managing data transfers between peripherals and main memory. We then focus on the main memory, exploring the different types of memory technologies, including DRAMs, SDRAMs, and DDR SDRAMs, and their roles in storing and accessing data effectively. Moving forward, we delve into the critical role of cache memory in improving system performance through data locality and access speed optimizations. Finally, we explore the concept of virtual memory, unraveling how modern operating systems manage memory resources efficiently by leveraging secondary storage devices.

Microcontroller Exploits is a deep dive into advanced hardware hacking with detailed examples of real-world techniques and a comprehensive survey of vulnerabilities. In this advanced guide to hardware hacking, you'll learn how to read the software out of single chip computers, especially when they are configured not to allow the firmware to be extracted. This book documents a very wide variety of microchip hacking techniques; it's not a beginner's first introduction. You'll start off by exploring detailed techniques for hacking real-world chips, such as how the STM32F0 allows for one word to be dumped after every reset. You'll see how the STM32F1’s exception handling can slowly leak the firmware out over an hour, and how the Texas Instruments MSP430 firmware can be extracted by a camera flash. For each exploit, you'll learn how to reproduce the results, dumping a chip in your own lab. In the second half of the book you'll find an encyclopedic survey of vulnerabilities, indexed and cross referenced for use in practicing hardware security. Numbered chapters provide in-depth explanations of either techniques or how to hack a specific chip. These are roughly grouped together with chapters that introduce a type of technique. Lettered chapters attempt to quickly group targets, describing prior research succinctly. Memory maps are provided to help you think of memory addresses as specific places, and wherever possible I’ve included X-ray and die photographs from my own lab.
