Embedded systems exist almost everywhere since 95% of the current market chips contains embedded devices; they can be seen as the brain of such systems. They control everything in their platforms such as access, store and processing of data. They are typically dedicated to perform specific tasks. They range from portable devices such as smart phones and MP3 players to a very complex one such as systems controlling air planes or automotive. Their complexity varies from a single system, which includes a single processing unit, to very complicated one with multiple units. They are designed to be used in many applications in our daily life such as educational, industrial and medical. Due to increases in the complexity of those systems with their tightened constraints on time and power dissipation as well as the scope of environment where they operate comes the need to estimate their performance metrics which include delay, for both processing and communication, and power consumption. Thereby achieving high quality of performance estimations is crucial and critical as well. Designing performance model and evaluation approaches to find system performance metrics is considered essential at an early stage of implementation foranefficient design especially real-time systems. Constructing performance models and evaluation techniques of a given system requires a significant effort. Therefore, it becomes crucial to develop a framework that is able to estimate response time and power consumption in the early stage of design and implementation to avoid unexpected things such as increasing in the project costs, reducing in the productivity and delaying in the schedule. In this work, we developed a framework to be able to perform analytical analysis to estimate performance metrics â€response time and power consumption†for any embedded system during design phase. In this research we refer to the response time â€delay†as the combination of the computation delay of software processes and communication as one of the different software architectures and hardware platforms. In order to achieve this, Hierarchical Performance Modeling (HPM) as a technique is used to find the expected average system performance for different layers of abstraction. HPM has been proven to be a powerful tool in terms of estimating delay or power consumption since it involves four layers of abstraction which can be summarized as follows: 1. System Level, 2. Task Level, 3. Module Level and 4. Operation Level. We are proposing a Hierarchical Generic Finite State Machine (HGFSM) which is used to link (map) between functional modeling analysis approaches such as FSM, Petri-Net and UML with the HPM. We also investigated the performance metrics (in terms of response time and power consumption) for an Android platform. Several hardware platforms are used to estimate the expected average value of both metrics and show the difference between it and the average actual values. The designing framework can be used to determine the bottleneck(s) in a system under investigation as we used it in the Android platforms. The output from the framework is performance equations which can be seen as Objective Functions. Then, we minimized the response time in Android platforms using a parallelization approach with GPUs invocation and monitoring the consequences in code size and power consumption. In addition, we developed a method to minimize the response time in embedded systems during run-time phase by scheduling their aperiodic tasks in an appropriate way to reduce their average waiting and turn-around times while maintaining system stability. Furthermore, we developed a scheme to 1) improve response time if possible and 2) ensure that all tasks (processes or jobs) meet their deadlines for periodic tasks in real-time system using Worst-Case Execution Time â€WCET†as a factor to decide which task or a set of tasks must be chosen first among several processes or sets exist in a system under investigation. Moreover, we used different probability distributions (pdf) to schedule periodic tasks in real-time systems. In many real-time applications such as multimedia, both audio and data processing and transmission offer a great variation. So using WCET as a factor may lead to undesirable results. Using different probability distributions (pdfs) to estimate the remaining time dynamically is called the moving average remaining time since the computed remaining time changes as a used distribution changes too whenever a task is added or removed from it. The purpose from previous approach is to ensure that all tasks meet their deadlines while maintaining system stability. Lastly, we utilize the designing framework to estimate response time in fire and pollution detection systems.

It is well known that embedded systems have to be implemented efficiently. This requires that processors optimized for certain application domains are used in embedded systems. Such an optimization requires a careful exploration of the design space, including a detailed study of cost/performance tradeoffs. In order to avoid time-consuming assembly language programming during design space exploration, compilers are needed. In order to analyze the effect of various software or hardware configurations on the performance, retargetable compilers are needed that can generate code for numerous different potential hardware configurations. This book provides a comprehensive and up-to-date overview of the fast developing area of retargetable compilers for embedded systems. It describes a large set important tools as well as applications of retargetable compilers at different levels in the design flow. Retargetable Compiler Technology for Embedded Systems is mostly self-contained and requires only fundamental knowledge in software and compiler design. It is intended to be a key reference for researchers and designers working on software, compilers, and processor optimization for embedded systems.

Learning to perform complex action strategies is an important problem in the fields of artificial intelligence, robotics, and machine learning. Filled with interesting new experimental results, Learning in Embedded Systems explores algorithms that learn efficiently from trial-and error experience with an external world. It is the first detailed exploration of the problem of learning action strategies in the context of designing embedded systems that adapt their behavior to a complex, changing environment; such systems include mobile robots, factory process controllers, and long-term software databases. Kaelbling investigates a rapidly expanding branch of machine learning known as reinforcement learning, including the important problems of controlled exploration of the environment, learning in highly complex environments, and learning from delayed reward. She reviews past work in this area and presents a number of significant new results. These include the intervalestimation algorithm for exploration, the use of biases to make learning more efficient in complex environments, a generate-and-test algorithm that combines symbolic and statistical processing into a flexible learning method, and some of the first reinforcement-learning experiments with a real robot.

This book introduces Software Thermal Management (STM) as a means of reducing power consumption in a computing system in order to manage heat, improve component reliability and increase system safety. Readers will benefit from this pragmatic guide to the field of STM for embedded systems and its catalog of software power management techniques. Since thermal management is a key bottleneck in embedded systems design, this book focuses on root cause of heat in embedded systems: power. Since software has an enormous impact on power consumption in an embedded system, this book urges software engineers to manage heat effectively by understanding, categorizing and developing new ways to reduce static and dynamic power consumption. Whereas most books on thermal management describe mechanisms to remove heat, this book focuses on ways for software engineers to avoid generating heat in the first place.

This book describes model-based development of adaptive embedded systems, which enable improved functionality using the same resources. The techniques presented facilitate design from a higher level of abstraction, focusing on the problem domain rather than on the solution domain, thereby increasing development efficiency. Models are used to capture system specifications and to implement (manually or automatically) system functionality. The authors demonstrate the real impact of adaptivity on engineering of embedded systems by providing several industrial examples of the models used in the development of adaptive embedded systems.

"Models of Computation for Heterogeneous Embedded Systems" presents a model of computation for heterogeneous embedded systems called DFCharts. It targets heterogeneous systems by combining finite state machines (FSM) with synchronous dataflow graphs (SDFG). FSMs are connected in the same way as in Argos (a Statecharts variant with purely synchronous semantics) using three operators: synchronous parallel, refinement and hiding. The fourth operator, called asynchronous parallel, is introduced in DFCharts to connect FSMs with SDFGs. In the formal semantics of DFCharts, the operation of an SDFG is represented as an FSM. Using this representation, SDFGs are merged with FSMs so that the behaviour of a complete DFCharts specification can be expressed as a single, flat FSM. This allows system properties to be verified globally. The practical application of DFCharts has been demonstrated by linking it to widely used system-level languages Java, Esterel and SystemC.
