Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "High-level synthesis systems design circuits that consist of a datapath and a controller. The datapath is a network of modules that is capable of performing the specified behavior. The controller is a circuit that delivers the proper sequence of control signals to the modules of the datapath. The activity in which the controller is designed is known as controller synthesis. Controller synthesis is important because controllers can take up a large fraction of the total circuit area, and so contribute substantially to production cost. Controller synthesis begins with a specification of the controller as a multiple-output multiple-valued logic function. To build the controllercircuit, binary codes are selected to represent the multiple-valued logic values. The selection of representative binary codes often has a substantial impact on the quality of the final circuit. In encoding problems, the goal is to select representative binary codes for which the value of some objective function is optimal. This thesis addresses several encoding problems that arise in controller synthesis. One encoding problem addressed in the thesis is a variation of the state assignment problem where the target circuit includes a counter. Other encoding problems considered in the thesis try to find encodings for which the results of a minimization procedure called column compaction are optimal. The thesis includes a detailed explanation of column compaction, and a novel algorithm for optimal column compaction."

This book was released on 2012-12-06 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade there has been a dramatic change in the role played by design automation for electronic systems. Ten years ago, integrated circuit (IC) designers were content to use the computer for circuit, logic, and limited amounts of high-level simulation, as well as for capturing the digitized mask layouts used for IC manufacture. The tools were only aids to design-the designer could always find a way to implement the chip or board manually if the tools failed or if they did not give acceptable results. Today, however, design technology plays an indispensable role in the design ofelectronic systems and is critical to achieving time-to-market, cost, and performance targets. In less than ten years, designers have come to rely on automatic or semi automatic CAD systems for the physical design ofcomplex ICs containing over a million transistors. In the past three years, practical logic synthesis systems that take into account both cost and performance have become a commercial reality and many designers have already relinquished control ofthe logic netlist level of design to automatic computer aids. To date, only in certain well-defined areas, especially digital signal process ing and telecommunications. have higher-level design methods and tools found significant success. However, the forces of time-to-market and growing system complexity will demand the broad-based adoption of high-level, automated methods and tools over the next few years.

This book was released on 2021-01-01 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, a set of modeling and control strategies are proposed for Cyberphysical systems (CPS), which aim at ensuring a safe, reliable, and highly performant operation of each local subsystem contained in the CPS. Modeling of CPS is challenging since not only must the tight interconnection of continuous and discrete dynamics of local subsystems be exactly represented, but so must also the interleaving structure between different subsystems. Optimal control of CPS, accordingly, should take into account not only the local mixed dynamics by local controller synthesis, but also the influence from other subsystems around.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the Fourth Workshop on Hybrid - stems: Computation and Control (HSCC 2001) held in Rome, Italy on March 28-30, 2001. The Workshop on Hybrid Systems attracts researchers from in- stry and academia interested in modeling, analysis, synthesis, and implemen- tion of dynamic and reactive systems involving both discrete (integer, logical, symbolic) and continuous behaviors. It is a forum for the discussion of the - test developments in all aspects of hybrid systems, including formal models and computational representations, algorithms and heuristics, computational tools, and new challenging applications. The Fourth HSCC International Workshop continues the series of workshops held in Grenoble, France (HART’97), Berkeley, California, USA (HSCC’98), N- megen, The Netherlands (HSCC’99), and Pittsburgh, Pennsylvania, USA (HSCC 2000). Proceedings of these workshops have been published in the Lecture Notes in Computer Science (LNCS) series by Springer-Verlag. In line with the beautiful work that led to the design of the palace in which the workshop was held, Palazzo Lancellotti in Rome, resulting from the col- boration of many artists and architects of di erent backgrounds, the challenge faced by the hybrid system community is to harmonize and extract the best from two main research areas: computer science and control theory.

This book was released on 2020-01-01 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The integration of intelligent, autonomously acting systems into modern society is a rapidly growing field. After robots are established for simple, recurring processes in industry and everyday life, more complex tasks are of interest which require the systems to consider the environment in their decision making process. In the future, intelligent systems will get access to fields like autonomous driving cars, unmanned aerial vehicle (UAV), manufacturing processes, household, or the assistance to people in need of care. The fast calculation of optimal circumventing trajectories is therefore an essential component to be able to integrate intelligent systems into our environment at all. The ambitious goal of real-time interaction between a human and an autonomous system is challenging. An autonomous system has to react timely on human motion such that a real interaction can be established. Thus, the autonomous system must continuously capture its environment and adapt its solution. If the system additionally determines a solution with respect to a certain optimization criterion, the computation times quickly rise, and real-time capability moves far away. To solve this problem, the thesis proposes an algorithmic control procedure which determines optimal collision-free trajectories fast. Therefore, a concept which uses homotopy properties in the control procedure is introduced. This allows to determine near-optimal solutions much faster than by commonly used techniques. At the beginning, an algorithmic procedure is shown for linear systems. It selects an optimized, circumventing trajectory based on the current obstacle location, and adapts its trajectory when the obstacle moves. Since real physical systems always underlie actuator limitations like e.g. motor torques, the provided method also considers input constraints. The developed method is subsequently extended to consider predictions of a moving obstacle. Thus, the procedure can further reduce the costs of the executed trajectory and is able to detect and avoid a collision at an early stage. Since many real-world system are described by nonlinear dynamics, the introduced method is also extended to nonlinear systems. The effectiveness of the proposed approach is shown in several simulations. Motivated by the results, the developed approach is extended to more complex tasks, like the collision avoidance between geometric bodies, and to multi agent systems that cooperatively determine solution trajectories in real-time, by means of the homotopy properties. Simulation results of a collision avoidance scenario for a robotic manipulator show, that with the proposed technique good results can be obtained in real-time.
Download or read book Models in System Design written by Jean-Michel Bergé and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Models in System Design tracks the general trend in electronics in terms of size, complexity and difficulty of maintenance. System design is by nature combined with prototyping, mixed domain design, and verification, and it is no surprise that today's modeling and models are used in various levels of system design and verification. In order to deal with constraints induced by volume and complexity, new methods and techniques have been defined. Models in System Design provides an overview of the latest modeling techniques for use by system designers. The first part of the book considers system level design, discussing such issues as abstraction, performance and trade-offs. There is also a section on automating system design. The second part of the book deals with some of the newest aspects of embedded system design. These include co-verification and prototyping. Finally, the book includes a section on the use of the MCSE methodology for hardware/software co-design. Models in System Design will help designers and researchers to understand these latest techniques in system design and as such will be of interest to all involved in embedded system design.

Download or read book Hardware Design and Petri Nets written by Alex Yakovlev and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardware Design and Petri Nets presents a summary of the state of the art in the applications of Petri nets to designing digital systems and circuits. The area of hardware design has traditionally been a fertile field for research in concurrency and Petri nets. Many new ideas about modelling and analysis of concurrent systems, and Petri nets in particular, originated in theory of asynchronous digital circuits. Similarly, the theory and practice of digital circuit design have always recognized Petri nets as a powerful and easy-to-understand modelling tool. The ever-growing demand in the electronic industry for design automation to build various types of computer-based systems creates many opportunities for Petri nets to establish their role of a formal backbone in future tools for constructing systems that are increasingly becoming distributed, concurrent and asynchronous. Petri nets have already proved very effective in supporting algorithms for solving key problems in synthesis of hardware control circuits. However, since the front end to any realistic design flow in the future is likely to rely on more pragmatic Hardware Description Languages (HDLs), such as VHDL and Verilog, it is crucial that Petri nets are well interfaced to such languages. Hardware Design and Petri Nets is divided into five parts, which cover aspects of behavioral modelling, analysis and verification, synthesis from Petri nets and STGs, design environments based on high-level Petri nets and HDLs, and finally performance analysis using Petri nets. Hardware Design and Petri Nets serves as an excellent reference source and may be used as a text for advanced courses on the subject.
