When planning the development of modern embedded systems, hardware and software cannot be considered independently. Over the last two decades chip and system complexity has seen an enormous amount of growth, while more and more system functionality has moved from dedicated hardware implementation into software executing on general-purposed embedded processors. By 2010 the development effort for software had outgrown the development efforts for hardware, and the complexity trend continues in favor of software. Traditional design techniques such as independent hardware and software design are being challenged due to heterogeneous models and applications being integrated to create a complex system on chip. Using proper techniques of hardware-software codesign, designers consider the trade-offs in the way hardware and software components of a system work together to exhibit a specified behavior, given a set of performance goals and technology. This chapter will cover these topics.

A PRACTICAL GUIDE TO HARDWARE FUNDAMENTALS Embedded Systems Hardware for Software Engineers describes the electrical and electronic circuits that are used in embedded systems, their functions, and how they can be interfaced to other devices. Basic computer architecture topics, memory, address decoding techniques, ROM, RAM, DRAM, DDR, cache memory, and memory hierarchy are discussed. The book covers key architectural features of widely used microcontrollers and microprocessors, including Microchip's PIC32, ATMEL's AVR32, and Freescale's MC68000. Interfacing to an embedded system is then described. Data acquisition system level design considerations and a design example are presented with real-world parameters and characteristics. Serial interfaces such as RS-232, RS-485, PC, and USB are addressed and printed circuit boards and high-speed signal propagation over transmission lines are covered with a minimum of math. A brief survey of logic families of integrated circuits and programmable logic devices is also contained in this in-depth resource. COVERAGE INCLUDES: Architecture examples Memory Memory address decoding Read-only memory and other related devices Input and output ports Analog-to-digital and digital-to-analog converters Interfacing to external devices Transmission lines Logic families of integrated circuits and their signaling characteristics The printed circuit board Programmable logic devices Test equipment: oscilloscopes and logic analyzers

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

Real-time operating systems (RTOS) are ubiquitous in embedded systems. This chapter explains what a real-time kernel is and what services it provides the product developer, and explains some of the internals of a kernel. A kernel is a component of an RTOS. In this chapter, we’ll look at task management, interrupt handling, scheduling, context switching, time management, resource management, message passing, priority inversions and much more.

This chapter focuses on the software development tools for embedded systems, especially on the debugging and investigation tools. The chapter starts by presenting the capabilities of a source code debugger – a tool that allows the developer to see what is inside his program at the current execution point or at the moment when the program crashed. The debugger features are described using as an example one of the most popular and widely used debuggers, GDB – GNU Debugger, provided by Free Software Foundation. In order to cover all the requirements of an embedded system, the chapter presents in the following how to design a debug agent that fits into our special target requirements starting from a simple debug routine and evolving to a fully featured debugger. It also presents the typical use cases and the key points of the design like context switching, position-independent executables, debug event handling and multi-core. It then presents the benefits of using the JTAG, an external device used to connect the debugger directly to the target, allowing the debugger to have full control of the target and its resources. Toward the end the chapter presents other tools that may help in the debugging process, like integrated development tools based on free open-source software (Eclipse, GDB), instrumented code and analysis tools.

This chapter introduces the automotive system, which is unlike any other, characterized by its rigorous planning, architecting, development, testing, validation and verification. The physical task of writing embedded software for automotive applications versus other application areas is not significantly different from other embedded systems, but the key differences are the quality standards which must be followed for any development and test project. To write automotive software the engineer needs to understand how and why the systems have evolved into the complex environment it is today. They must be aware of the differences and commonalties between the automotive submarkets. They must be familiar with the applicable quality standards and why such strict quality controls exist, along with how quality is tested and measured, all of which are described in this chapter with examples of the most common practices. This chapter introduces various processes to help software engineers write high-quality, fault-tolerant, interoperable code such as modeling, autocoding and advanced trace and debug assisted by the emergence of the latest AUTOSAR and ISO26262 standards, as well as more traditional standards such as AEC, OBD-II and MISRA.

This chapter provides some guidelines that are commonly used in embedded software development. It starts with principles of programming, including readability, testability, and maintainability. The chapter then proceeds with discussing how to start an embedded software project, including considerations for hardware, file organization, and development guidelines. The focus then shifts to programming guidelines that are important to any software development project, which includes the importance of a syntax coding standard. The chapter concludes with descriptions of variables and definitions and how they are typically used in an embedded software project.

Creating a model for your embedded system provides a time- and cost-effective approach to the development of simple or incredibly complex dynamic control systems, all based on a single model maintained in a tightly integrated software suite. Using modern modeling software tools you can design and perform initial validation in off-line simulation. These models then form the basis for all subsequent development stages. Creating models for your embedded design provides numerous advantages over the traditional design approach. Using this approach – combined with hardware prototyping – you reduce the risk of mistakes and shorten the development cycle by performing verification and validation testing throughout the development instead of only during the final testing stage. Design evaluations and predictions can be made much more quickly and reliably with a system model as a basis. This iterative approach results in improved designs, in terms of both performance and reliability. The cost of resources is reduced, because of reusability of models between design teams, design stages, and various projects and the reduced dependency on physical prototypes. Development errors and overhead can be reduced through the use of automatic code-generation techniques. These advantages translate to more accurate and robust control designs, shorter time to market, and reduced design cost.
