This book is a practical engineering guide for designing and implementing a successful embedded product. To make a product successful starts from requirements which describe the functions, the characteristics, and the quality of the system. From the requirements, the process flows down to design, development, test, and maintenance.Key Features-Embedded System Life Cycle-Processor/DSP peripherals and communications-How to choose a microcontroller/DSP, memory, and peripheral devices-Real-Time Operating System-System verification and validation-RSA Public-Key Cryptosystems-Advanced Encryption Standard (AES)Book DescriptionThis book describes step by step through the life cycle, including requirement, design, implementation, integration test, and maintenance phases. It then introduces the microcontroller/DSP, how to choose a microcontroller, real-time operating system, software tools, booting process, verification and validation. Finally, it details the implementation of RSA Public-Key Cryptosystems and AES for the security.What you will learn-Understand the importance of the Embedded System Life Cycle-Choosing a microcontroller/DSP, memory, and peripherals-Choosing software tools and Real-Time Operating System (RTOS)-Implementation of RSA Public-Key Cryptosystems-Implementation of Advanced Encryption Standard (AES)Who this book for?This book will benefit any engineer or student who is interested in the embedded system or who is new to this field.Table of Contents1.What is an Embedded System?2.Scope of This Book and the Definition Terms3.Life Cycle of an Embedded System4.Evolution of Microprocessor/Microcontroller5.Digital Signal Processor6.Processor/DSP Peripherals and Communications7.How to Choose a Microcontroller or a DSP8.Big-Endian vs Little-Endian9.Memory10.Interrupt11.Watchdog Timer (WDT)12.Hardware Prototype13.Software Components14.Bare Metal System vs Real-Time Operating System (RTOS)15.Integrated Development Environment (IDE)16.Code Implementation17.Booting Process18.Verification and Validation19.Maintenance20.Mechanical Design21.RSA Public-Key Cryptosystems22.Advanced Encryption Standard (AES)23.Future of the Embedded System
