Barr Group's Embedded C Coding Standard was developed to help firmware engineers minimize defects in embedded systems. Unlike the majority of coding standards, this standard focuses on practical rules that keep bugs out - including techniques designed to improve the maintainability and portability of embedded software. The rules in this coding standard include a set of guiding principles, as well as specific naming conventions and other rules for the use of data types, functions, preprocessor macros, variables, and other C language constructs. Individual rules that have been demonstrated to reduce or eliminate certain types of defects are highlighted. The BARR-C standard is distinct from, yet compatible with, the MISRA C Guidelines for Use of the C Language in Critical Systems. Programmers can easily combine rules from the two standards as needed.
Encapsulating the wisdom and experience of their creators, coding standards such as the Motor Industry Software Reliability Association (MISRA) C and C11 coding standards, the JSF Airborne Vehicle C11 standard or the Netrino Embedded C ...

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

State of the art techniques and best practices in the development of embedded software apply not only to high-integrity devices (such as those for safety-critical applications like aircraft flight controllers, car braking systems or medical devices), but also to lesser-integrity applications when the need to optimize the effectiveness of the available test time and budget demands that pragmatic decisions should be made. To complement this multitude of software test techniques there is a similar plethora of test tools available to automate them. These tools are commonplace in the development of safety-critical applications, but elsewhere not everyone has the budget to buy all, or indeed any, of them. Of course, the providers of these tools would advocate the purchase of each and every one of them, so how can a limited budget best be allocated? And where no budget exists, how can similar principles be applied to provide confidence that the finished item is of adequate quality? In addressing these issues not only are the concepts behind the techniques presented, but also some “case study” software code examples to drill a little deeper and illustrate how some of them are implemented in practice.

Another day without Test-Driven Development means more time wasted chasing bugs and watching your code deteriorate. You thought TDD was for someone else, but it's not! It's for you, the embedded C programmer. TDD helps you prevent defects and build software with a long useful life. This is the first book to teach the hows and whys of TDD for C programmers. TDD is a modern programming practice C developers need to know. It's a different way to program---unit tests are written in a tight feedback loop with the production code, assuring your code does what you think. You get valuable feedback every few minutes. You find mistakes before they become bugs. You get early warning of design problems. You get immediate notification of side effect defects. You get to spend more time adding valuable features to your product. James is one of the few experts in applying TDD to embedded C. With his 1.5 decades of training,coaching, and practicing TDD in C, C++, Java, and C# he will lead you from being a novice in TDD to using the techniques that few have mastered. This book is full of code written for embedded C programmers. You don't just see the end product, you see code and tests evolve. James leads you through the thought process and decisions made each step of the way. You'll learn techniques for test-driving code right nextto the hardware, and you'll learn design principles and how to apply them to C to keep your code clean and flexible. To run the examples in this book, you will need a C/C++ development environment on your machine, and the GNU GCC tool chain or Microsoft Visual Studio for C++ (some project conversion may be needed).

This book constitutes the refereed proceedings of the 25th International Static Analysis Symposium, SAS 2018, held in Freiburg, Germany, in August 2018. The 18 papers presented in this volume were carefully reviewed and selected from 37 submissions. The contributions cover a variety of multi-disciplinary topics in abstract domains: program verication, bug detection, compiler optimization, program understanding, and software maintenance.
This change in the title reflects the growing adoption of MISRA C as a coding standard for general embedded systems. One of the other key attractions of MISRA C is that it was written by engineers and not by computer scientists.

The Designer’s Guide to the Cortex-M Family is a tutorial-based book giving the key concepts required to develop programs in C with a Cortex M- based processor. The book begins with an overview of the Cortex- M family, giving architectural descriptions supported with practical examples, enabling the engineer to easily develop basic C programs to run on the Cortex- M0/M0+/M3 and M4. It then examines the more advanced features of the Cortex architecture such as memory protection, operating modes and dual stack operation. Once a firm grounding in the Cortex M processor has been established the book introduces the use of a small footprint RTOS and the CMSIS DSP library. With this book you will learn: The key differences between the Cortex M0/M0+/M3 and M4 How to write C programs to run on Cortex-M based processors How to make best use of the Coresight debug system How to do RTOS development The Cortex-M operating modes and memory protection Advanced software techniques that can be used on Cortex-M microcontrollers How to optimise DSP code for the cortex M4 and how to build real time DSP systems An Introduction to the Cortex microcontroller software interface standard (CMSIS), a common framework for all Cortex M- based microcontrollers Coverage of the CMSIS DSP library for Cortex M3 and M4 An evaluation tool chain IDE and debugger which allows the accompanying example projects to be run in simulation on the PC or on low cost hardware

“At Cisco, we have adopted the CERT C Coding Standard as the internal secure coding standard for all C developers. It is a core component of our secure development lifecycle. The coding standard described in this book breaks down complex software security topics into easy-to-follow rules with excellent real-world examples. It is an essential reference for any developer who wishes to write secure and resilient software in C and C++.” —Edward D. Paradise, vice president, engineering, threat response, intelligence, and development, Cisco Systems Secure programming in C can be more difficult than even many experienced programmers realize. To help programmers write more secure code, The CERT® C Coding Standard, Second Edition, fully documents the second official release of the CERT standard for secure coding in C. The rules laid forth in this new edition will help ensure that programmers’ code fully complies with the new C11 standard; it also addresses earlier versions, including C99. The new standard itemizes those coding errors that are the root causes of current software vulnerabilities in C, prioritizing them by severity, likelihood of exploitation, and remediation costs. Each of the text’s 98 guidelines includes examples of insecure code as well as secure, C11-conforming, alternative implementations. If uniformly applied, these guidelines will eliminate critical coding errors that lead to buffer overflows, format-string vulnerabilities, integer overflow, and other common vulnerabilities. This book reflects numerous experts’ contributions to the open development and review of the rules and recommendations that comprise this standard. Coverage includes Preprocessor Declarations and Initialization Expressions Integers Floating Point Arrays Characters and Strings Memory Management Input/Output Environment Signals Error Handling Concurrency Miscellaneous Issues
