Designing Secure IoT devices with the Arm Platform Security Architecture and Cortex-M33 explains how to design and deploy secure IoT devices based on the Cortex-M23/M33 processor. The book is split into three parts. First, it introduces the Cortex-M33 and its architectural design and major processor peripherals. Second, it shows how to design secure software and secure communications to minimize the threat of both hardware and software hacking. And finally, it examines common IoT cloud systems and how to design and deploy a fleet of IoT devices. Example projects are provided for the Keil MDK-ARM and NXP LPCXpresso tool chains. Since their inception, microcontrollers have been designed as functional devices with a CPU, memory and peripherals that can be programmed to accomplish a huge range of tasks. With the growth of internet connected devices and the Internet of Things (IoT), "plain old microcontrollers” are no longer suitable as they lack the features necessary to create both a secure and functional device. The recent development by ARM of the Cortex M23 and M33 architecture is intended for today's IoT world. Shows how to design secure software and secure communications using the ARM Cortex M23- and M33-based micro controllers Explains how to write secure code to minimize vulnerabilities using the CERT-C coding standard Uses the mbedTLS library to implement modern cryptography

Fast and Effective Embedded Systems Design is a fast-moving introduction to embedded system design, applying the innovative ARM mbed and its web-based development environment. Each chapter introduces a major topic in embedded systems, and proceeds as a series of practical experiments, adopting a "learning through doing" strategy. Minimal background knowledge is needed. C/C++ programming is applied, with a step-by-step approach which allows the novice to get coding quickly. Once the basics are covered, the book progresses to some "hot" embedded issues – intelligent instrumentation, networked systems, closed loop control, and digital signal processing. Written by two experts in the field, this book reflects on the experimental results, develops and matches theory to practice, evaluates the strengths and weaknesses of the technology or technique introduced, and considers applications and the wider context. Numerous exercises and end of chapter questions are included. - A hands-on introduction to the field of embedded systems, with a focus on fast prototyping - Key embedded system concepts covered through simple and effective experimentation - Amazing breadth of coverage, from simple digital i/o, to advanced networking and control - Applies the most accessible tools available in the embedded world - Supported by mbed and book web sites, containing FAQs and all code examples - Deep insights into ARM technology, and aspects of microcontroller architecture - Instructor support available, including power point slides, and solutions to questions and exercises

The Arm(R) Cortex(R)-M processors are already one of the most popular choices for loT and embedded applications. With Arm Flexible Access and DesignStart(TM), accessing Arm Cortex-M processor IP is fast, affordable, and easy. This book introduces all the key topics that system-on-chip (SoC) and FPGA designers need to know when integrating a Cortex-M processor into their design, including bus protocols, bus interconnect, and peripheral designs. Joseph Yiu is a distinguished Arm engineer who began designing SoCs back in 2000 and has been a leader in this field for nearly twenty years. Joseph's book takes an expert look at what SoC designers need to know when incorporating Cortex-M processors into their systems. He discusses the on-chip bus protocol specifications (AMBA, AHB, and APB), used by Arm processors and a wide range of on-chip digital components such as memory interfaces, peripherals, and debug components. Software development and advanced design considerations are also covered. The journey concludes with 'Putting the system together', a designer's eye view of a simple microcontroller-like design based on the Cortex-M3 processor (DesignStart) that uses the components that you will have learned to create.
