Embedded System Development Process
It is the megatrend in today's digital connected world, each and every personal gadget from palmtop, smart cellular, game set top box, to wearable devices, is getting thinner, lighter, shorter, smaller, and, of course, low power. The global competition and shorter product life cycle post a major challenge to the product development. It is getting harder to meet customer's demands on time because customers want the products to be done as early as possible. The reason is simple: competitions are so high and the technology advances are so fast. Because the time to market is very short for a new product introduction, the development of a new product is often started too hastily, no development plan, do not follow the golden process flow, no thorough reviews, incomplete test cases, waive bugs, etc., so engineers and developers have to repeat what they have done to fix things, in the end everything takes much longer than it should be. A good design flow can reduce time to market; meanwhile improve product's quality. Software development is usually questionable for its poor quality and unreliability. Buggy code, improper interfaces and missing features are almost encountered by the users of most embedded system. The embedded system developers are filled with consequence of missed deadlines, and huge cost overruns. Embedded system developers can benefit from high quality design flow by identifying optimal product architecture and executing a high quality design process. Embedded software development tools are also vitally important for productive development and keeping development in control. The purpose of writing this software design process flow is to ensure that, by following a high quality process and right set of development tools the developers shall possess the highest quality of products while maintaining a competitive schedule and a lower cost structure.Book Contents: Chapter 1: Introductions. Define embedded system and development process.Chapter 2: Describe a time-task span of the embedded system development process. Chapter 3, 4, 5, and 6: Each Chapter describes the four phases of the design and development process respectively, which are plan phase (Chapter 3), design phase (chapter 4), integrated development phase (Chapter 5), design verification and validation phase (Chapter 6). The design phase (Chapter 4) consists of six parallel stages: hardware, firmware, software, ASIC, FPGA, and mechanical (not each stage are required in all embedded system design). In this book, Chapter 4, firmware is considered equivalent to software for embedded system development process. Chapter 4 only deals with software design process, other design stages shall be covered by separate contents. In additional to development process, software design techniques are also discussed in chapter 4 and appendixes.Appendix 1 gives a template for Embedded System Development Plan. Appendix 4 to Appendix 9 provides coding guidelines and software review checklists. Appendix 10 to Appendix 12 lists few popular IDE development tools for the embedded system design.Audience: This book is intentionally written for: Managers and team leaders who need to guide embedded software design and development process.Software engineers and new designers who want to optimize software design and development process.New graduates and students who want to learn software design and development process.Interested readers who want to explore software design and development proce
Embedded System Development Process
Almost each and every electronic gadget around us is an embedded system, for example: Smart phone, palmtop, digital watch, digital camera, printer, scanner, washer machine control panel, home security system, and many more. Embedded systems have revolutionized our society into a digital world due to the fact that they are microcontroller-based, compact in sizes, reliable in performance, and cheaper in cost. Book ContentsThis book will assist you to learn about embedded systems, its design and development process. Four serial phases: plan, design, integrated development (ID), design verification and validation (DV&V) are presented and discussed in this book.This book begins by introducing what the embedded system basics are. Chapter 1 present classification and aspect of embedded systems, describes embedded systems' hardware and software characteristics. Then it is continued by chapter 2 to depict a time-task span of the embedded system product development process.Chapter 3, 4, 5, and 6, each describes the four phases of the design and development process respectively, which are Plan (Chapter 3), Design (chapter 4), Integrated Development (Chapter 5), Design Verification and Validation (Chapter 6). Plan phase (Chapter 3) describes product requirement, cost analysis, development strategy, management plan, development methodology, design tools and equipment.Design phase (Chapter 4) go over each design process flows, and present descriptions on: hardware board design process, hardware PCB design process, signal integrity analysis and simulation, software design process, and FPGA design process.Integrated Development phase (Chapter 5) discuss on: mechanical and PCB preparations, parts acquisition, FPGA preparation, PCB assembly, hardware testing and debug, hardware/software integrated development, and virtual prototype.Design Verification and Validation phase (Chapter 6) present appearance inspection, functional testing, characteristics and measurements, performance testing, and ESD, EMC, safety testing.Appendixes in this book provide tables and descriptions on hardware and software design checklists, guidelines, and development tools for reference. Bold texts in the paragraphs shall represent a development process name, phase name, step name, or a term of the glossary, or an emphasis.Audience: This book is intentionally written for following audience: -Managers and team leaders who need to manage and guide embedded system design and development process effectively.-Engineers and technicians who want to speed up and optimize embedded system design and development process.-New graduates and students who want to study and learn embedded system design and development process.-Interested readers who want explore embedded system design and development process.
Embedded and Real Time System Development: A Software Engineering Perspective
Nowadays embedded and real-time systems contain complex software. The complexity of embedded systems is increasing, and the amount and variety of software in the embedded products are growing. This creates a big challenge for embedded and real-time software development processes and there is a need to develop separate metrics and benchmarks. “Embedded and Real Time System Development: A Software Engineering Perspective: Concepts, Methods and Principles” presents practical as well as conceptual knowledge of the latest tools, techniques and methodologies of embedded software engineering and real-time systems. Each chapter includes an in-depth investigation regarding the actual or potential role of software engineering tools in the context of the embedded system and real-time system. The book presents state-of-the art and future perspectives with industry experts, researchers, and academicians sharing ideas and experiences including surrounding frontier technologies, breakthroughs, innovative solutions and applications. The book is organized into four parts “Embedded Software Development Process”, “Design Patterns and Development Methodology”, “Modelling Framework” and “Performance Analysis, Power Management and Deployment” with altogether 12 chapters. The book is aiming at (i) undergraduate students and postgraduate students conducting research in the areas of embedded software engineering and real-time systems; (ii) researchers at universities and other institutions working in these fields; and (iii) practitioners in the R&D departments of embedded system. It can be used as an advanced reference for a course taught at the postgraduate level in embedded software engineering and real-time systems.
