Embedded Systems & Microelectronics Explained: Design & Applications

Abstract

Embedded Systems & Microelectronics Explained: Design & Applications is a publication-grade Open Educational Resource (OER) module covering the microarchitectural, physical packaging, real-time firmware, and power optimization principles governing edge compute nodes. Serving as an integral core module within the Electrical and Electronic Engineering curriculum on Prep4Uni.Online, this text bridges low-level C firmware, real-time operating system (RTOS) scheduling, and serial bus protocols with contemporary AI-era edge inference, custom silicon architectures, and IoT hardware. Key Features & Pedagogical Additions:• Theoretical Grounding & Contemporary Paradigms: Integrates classical embedded computing concepts (interrupt latency, timer prescalers, memory hierarchies, sub-threshold leakage physics) with TinyML quantized neural networks (INT8), Physics-Informed Neural Networks (PINNs) solving 3D Fourier heat conduction for real-time silicon thermal throttling, and Lie-group SE(3) Invariant Extended Kalman Filters (IEKF) for edge state estimation.• Systems Engineering Architecture & Trade-Off Analysis: Structured comparison matrix contrasting bare-metal interrupt loops against RTOS kernels, SPI against I2C bus bandwidths, microcontrollers against FPGAs, and internal static SRAM against external Quad-SPI Execute-in-Place (XIP) flash.• Worked Numerical Engineering Application: A complete, multi-step engineering calculation detailing a low-power duty-cycled IoT telemetry node, quantifying state electric charges, average current consumption, derated battery capacity, and annual self-discharge lifespans.• Curricular Assessment & Analytical Inquiries: Contains 29 fully resolved foundational review questions, deep analytical design inquiries, and step-by-step numerical problems spanning ADC LSB resolution and digital quantization code derivation, microcontroller power dissipation profiling, coin cell battery lifetime estimation, SPI packet transmission latency, timer prescaler frequency calculations, 16-bit interrupt reload value synthesis, and I2C bus RC rise-time verification.
