A recent survey stated that 52% of embedded projects are late by 4-5 months. This book can help get those projects in on-time with design patterns. The author carefully takes into account the special concerns found in designing and developing embedded applications specifically concurrency, communication, speed, and memory usage. Patterns are given in UML (Unified Modeling Language) with examples including ANSI C for direct and practical application to C code. A basic C knowledge is a prerequisite for the book while UML notation and terminology is included. General C programming books do not include discussion of the contraints found within embedded system design. The practical examples give the reader an understanding of the use of UML and OO (Object Oriented) designs in a resource-limited environment. Also included are two chapters on state machines. The beauty of this book is that it can help you today. . - Design Patterns within these pages are immediately applicable to your project - Addresses embedded system design concerns such as concurrency, communication, and memory usage - Examples contain ANSI C for ease of use with C programming code

Embedded software has traditionally been developed as a one-off software development effort designed for an individual product. In recent years, embedded system complexity has dramatically increased and the microcontrollers capabilities have followed. What were once simple 8-bit computing machines running at a few dozen megahertz have now become full-fledged 32-bit processors executing at hundreds of megahertz's. Developing software from scratch or for use in a single application or processor has become extremely costly and problematic for design teams. This API standard for microcontrollers is an example hardware abstraction layer designed to help embedded software developers designing products with microcontrollers create reusable software that abstracts out the hardware. This API standard has been developed and used in production systems for more than half a decade in devices ranging from automotive and medical devices to space systems. Each iteration that it has gone through has helped create a standard that flexible for developers and meets many general real-time design needs. Using an API to abstract out the microcontroller has several major benefits to development teams such as: Removing the specialized need to master the microcontroller hardware Decreasing costs through reusable firmware Faster times to market Better planning and accuracy in the development cycle Portability and flexibility to handle numerous applications Undoubtedly there are many more benefits but in this book the goal is to provide the reader with the standard. If you are interested in understanding how to develop reusable software and the processes that a developer would go through to create their own API's and HAL's, the companion book "Developing Reusable Firmware : A Practical Approach", can be found at www.beningo.com. Developing Reusable Firmware discusses the key ideas behind creating API's and HAL's along with the processes and design considerations that developers need to consider when creating their own. This standard example has gone through many iterations and has become very stable but there is always an opportunity that changes will be made in the future. In order to stay up to date and receive the latest information and also receive the associated API template files, please visit the associated webpage at https://www.beningo.com/api/index.php to sign-up. When you sign-up you will receive Doxygen template source files that layout the entire standard in way that can be easily modified to implement in your own development cycle. I wish you the best of luck in using this standard and dramatically transforming the way in which you develop and reuse your embedded software.

Today, even the largest development organizations are turning to agile methodologies, seeking major productivity and quality improvements. However, large-scale agile development is difficult, and publicly available case studies have been scarce. Now, three agile pioneers at Hewlett-Packard present a candid, start-to-finish insider’s look at how they’ve succeeded with agile in one of the company’s most mission-critical software environments: firmware for HP LaserJet printers. This book tells the story of an extraordinary experiment and journey. Could agile principles be applied to re-architect an enormous legacy code base? Could agile enable both timely delivery and ongoing innovation? Could it really be applied to 400+ developers distributed across four states, three continents, and four business units? Could it go beyond delivering incremental gains, to meet the stretch goal of 10x developer productivity improvements? It could, and it did—but getting there was not easy. Writing for both managers and technologists, the authors candidly discuss both their successes and failures, presenting actionable lessons for other development organizations, as well as approaches that have proven themselves repeatedly in HP’s challenging environment. They not only illuminate the potential benefits of agile in large-scale development, they also systematically show how these benefits can actually be achieved. Coverage includes: • Tightly linking agile methods and enterprise architecture with business objectives • Focusing agile practices on your worst development pain points to get the most bang for your buck • Abandoning classic agile methods that don’t work at the largest scale • Employing agile methods to establish a new architecture • Using metrics as a “conversation starter” around agile process improvements • Leveraging continuous integration and quality systems to reduce costs, accelerate schedules, and automate the delivery pipeline • Taming the planning beast with “light-touch” agile planning and lightweight long-range forecasting • Implementing effective project management and ensuring accountability in large agile projects • Managing tradeoffs associated with key decisions about organizational structure • Overcoming U.S./India cultural differences that can complicate offshore development • Selecting tools to support quantum leaps in productivity in your organization • Using change management disciplines to support greater enterprise agility

The book provides a clear understanding of what software reuse is, where the problems are, what benefits to expect, the activities, and its different forms. The reader is also given an overview of what sofware components are, different kinds of components and compositions, a taxonomy thereof, and examples of successful component reuse. An introduction to software engineering and software process models is also provided.

This book provides an overview of modern boot firmware, including the Unified Extensible Firmware Interface (UEFI) and its associated EFI Developer Kit II (EDKII) firmware. The authors have each made significant contributions to developments in these areas. The reader will learn to use the latest developments in UEFI on modern hardware, including open source firmware and open hardware designs. The book begins with an exploration of interfaces exposed to higher-level software and operating systems, and commences to the left of the boot timeline, describing the flow of typical systems, beginning with the machine restart event. Software engineers working with UEFI will benefit greatly from this book, while specific sections of the book address topics relevant for a general audience: system architects, pre-operating-system application developers, operating system vendors (loader, kernel), independent hardware vendors (such as for plug-in adapters), and developers of end-user applications. As a secondary audience, project technical leaders or managers may be interested in this book to get a feel for what their engineers are doing. The reader will find: An overview of UEFI and underlying Platform Initialization (PI) specifications How to create UEFI applications and drivers Workflow to design the firmware solution for a modern platform Advanced usages of UEFI firmware for security and manageability
