If you have the right tools, designing a microprocessor shouldn’t be complicated. The Verilog hardware description language (HDL) is one such tool. It can enable you to depict, simulate, and synthesize an electronic design, and thus increase your productivity by reducing the overall workload associated with a given project.Monte Dalrymple’s Microprocessor Design Using Verilog HDL is a practical guide to processor design in the real world. It presents the Verilog HDL in a straightforward fashion and serves as a detailed introduction to reducing the computer architecture and as an instruction set to practice. You’re led through the microprocessor design process from start to finish, and essential topics ranging from writing in Verilog to debugging and testing are laid bare.The book details the following, and more: Verilog HDL Review: data types, bit widths/labeling, operations, statements, and design hierarchy Verilog Coding Style: files vs. modules, indentation, and design organization Design Work: instruction set architecture, external bus interface, and machine cycle Microarchitecture: design spreadsheet and essential worksheets (e.g., Operation, Instruction Code, and Next State) Writing in Verilog: choosing encoding, assigning states in a state machine, and files (e.g., defines.v, hierarchy.v, machine.v) Debugging, Verification, and Testing: debugging requirements, verification requirements, testing requirements, and the test bench Post Simulation: enhancements and reduction to practice Monte Dalrymple received a BSEE (with highest honors) and an MSEE from the University of California at Berkeley, where he was elected to Phi Beta Kappa. Monte started his career at Zilog, where he designed a number of successful products, including the Serial Communication Controller (SCC) family and the Universal Serial Controller (USC) family. He was also the architect and lead designer of the Z380 microprocessor. Monte started his own company, Systemyde International Corp., in 1995, and has been doing contract design work ever since. He designed all five generations of Rabbit microprocessors, a Z180 clone that is flying on the Juno mission to Jupiter, and a Z8000 clone that flies in a commercial avionics air data computer. Monte holds 16 patents as well as both amateur and commercial radio licenses. Monte wrote 10 articles for Circuit Cellar magazine between 1996 and 2010.

AI Projects for the Raspberry Pi with the AI HAT+ Edge AI is transforming everyday devices by putting intelligence where it matters most: directly inside the hardware. With on-device inference, a camera can recognize a visitor instantly, a phone can translate speech without streaming audio to the cloud, and a wearable can detect anomalies in real time—fast, private, and reliable even when the network disappears. This book is your practical guide to building exactly those kinds of systems with the Raspberry Pi AI HAT+ and the Hailo-8L accelerator. You’ll start with clear foundations: core AI and machine-learning concepts, how neural networks work, and what truly distinguishes Edge AI from cloud AI—plus an honest look at ethical considerations and future impacts. Then it’s straight to hands-on physical computing. Step by step, you’ll set up Raspberry Pi OS, power and cooling, and develop in Python using the Thonny IDE. You’ll learn GPIO basics with lights and servos, mount the AI HAT+ hardware, install and verify the Hailo software stack, and connect the right camera—official modules or USB webcams, even multiple cameras. From your first pipeline to real projects, you’ll run person detection, pose estimation, segmentation, and depth estimation, then level up with YOLO object detection: smart alerts, guest counters, and custom extensions. You’ll even connect vision to motion by combining gesture recognition with servo-driven mechanisms, including a robotic arm. With troubleshooting tips, hardware essentials, and a practical Python refresher, this book turns Edge AI from buzzword into buildable reality.

This book discusses the basic components of any alarm system. All alarm systems have two basic functions. First, they monitor their environment looking for a change such as a door or window opening or someone moving about in the room. Second, they alert the legal owner or user to this change. The system described in this book uses a scanning type software to detect intruders. It behaves like a guard dog, pacing up and down the fence line on the lookout for either an intruder or a familiar person. If you have an alarm key, you can disarm the system and enter. With the scanning method, the software is easy to write and explain. It can scan eight alarm zones plus two special fire zones in about one second. You don’t have to be an electrical engineer to install an alarm system, just a decent carpenter, painter, and plasterer! Because this alarm system runs on 12 volts, you don’t have to be a licensed electrician either to install it. The alarm system presented here uses Python software on the Raspberry Pi combined with some elementary electronic circuits. The code described in the book, as well as CAD files and a bill of materials for the alarm panel, are available for free downloading. The book provides the reader with examples of typical configurations coming straight from the author‘s experience. After reviewing the hardware components typically used in common alarm systems, the author shows how to plan one yourself. To implement a modular alarm, no matter if it is for a single house or for a business or restaurant, the book shows how to skillfully combine a Raspberry Pi with small auxiliary electronic circuits. These are not installation instructions but food for thought that will enable readers to find a solution to their needs.

From SRPP and Mu-Follower to OTL Designs Tube amplifiers suffer from distortion. Fortunately, circuits such as the SRPP amplifier, mu-follower, and beta-follower produce minimal distortion even at output voltages of 50 to 100 Vpeak. These designs are often published with errors. Without a sound understanding of the theory, it is easy to arrive at a flawed design. In the first section of this book, we investigate the origin of distortion, while in the second we investigate the design of and SRPP and a mu-follower. On the internet we can find the most exotic designs. Evaluating them teaches us that these designs often make matters worse rather than better. In the chapter on incorrect SRPPs and mu-followers, we sometimes see bizarre and misguided designs where using a simple single-triode amplifier would perform much better. Push-pull output stages also exist. A great number of them are examined, and their similarity to the SRPP is discussed. This is done especially with the help of the theory behind the OTL based on the ‘mother’ of all OTLs, the Philips HF303. Finally, attention is given to frequency characteristics and technical matters such as the supply voltage and the filament power supply. To illustrate these points, there are a few designs covering the subjects discussed. This book presents much new theory that has not been published before. It is often an eye-opener, showing that many things have a beautiful and unexpected simplicity.

The Basics, New Ideas & Applications Build digital electronics from the ground up—and take it all the way to practical circuits you can use. This book guides you through the core principles of digital technology with a strongly hands-on approach. You’ll begin with the essentials: signals, devices for working with them, and what "logic 0" and "logic 1" mean in real hardware. Simple demonstration setups made from easy-to-find parts (LEDs, diodes, resistors, switches) help you see how logic behaves, making the theory click before you move on. From there, you’ll explore a wide range of logic elements and how they’re implemented, including classic logic families such as TTL and CMOS. The fundamentals section covers the building blocks of digital systems: flip-flops, Schmitt triggers, registers, counters and dividers, encoders/ decoders, multiplexers/demultiplexers, plus A/D and D/A conversion and timing circuits. Next, the book invites you into "new ideas" in digital electronics—universal logic elements, unconventional approaches (including thyristor-based and fractional logic), and creative logic functions that can inspire original designs. Finally, a large, well-organized collection of application circuits turns knowledge into projects: electronic switches and selectors, pulse generators, PWM regulators, frequency multipliers/dividers, phase shifters, and digital filters. Study it deeply, and you’ll gain not only understanding—but the ability to design and debug digital circuits independently.
