Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the design and performance analysis of SDRAM controllers that cater to both real-time and best-effort applications, i.e. mixed-time-criticality memory controllers. The authors describe the state of the art, and then focus on an architecture template for reconfigurable memory controllers that addresses effectively the quickly evolving set of SDRAM standards, in terms of worst-case timing and power analysis, as well as implementation. A prototype implementation of the controller in SystemC and synthesizable VHDL for an FPGA development board are used as a proof of concept of the architecture template.

This book was released on 2015 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we present a rank-switching open-row DRAM controller for mixed critical real time systems. This memory controller is optimized for multi-requestor and multi-rank memory systems. The key to improved performance is an innovative rank-switching mechanism which hides the latency of write to read transitions in DRAM devices without requiring unpredictable request reordering. We further employ open-row policy to take advantage of the data caching mechanism (row buffering) in each device. We choose the bank privatization scheme where each requestor is assigned its own private bank or set of banks. This private bank mapping guarantees that each requestor has its own row buffers and cannot be interfered by other requestors. The proposed memory controller design allows maximum of thirty two requestors at a time targeting either two or four ranks. This controller provides complete timing isolation between critical and non-critical applications and allows for compositional timing analysis over number of requestors and memory ranks in the system. We designed both the front end logic for the command generation and back end logic for the DRAM timing constraint check and arbitration utilizing the rank switching techniques. The complete design is implemented and synthesized using Verilog RTL and finally, we evaluated performance using various benchmarks. Our proposed memory controller offers significantly lower worst case latency bounds for critical real-time applications and supports average throughput for non-critical real-time applications compared to existing real time memory controllers in the literature.

Available in PDF, EPUB and Kindle. Book excerpt: This open access book introduces how to manage important tasks in industrial wireless networks. Important tasks must be completed on time and with guaranteed quality; that is the consensus reached by system designers and users. However, for too long, important tasks have often been given unnecessary urgency, and people intuitively believe that important tasks should be executed first so that their performance can be guaranteed. Actually, in most cases, their performance can be guaranteed even if they are executed later, and the “early” resources can be utilized for other, more urgent tasks. Therefore, confusing importance with urgency hinders the proper use of system resources. In 2007, mixed criticality was proposed to indicate that a system may contain tasks of various importance levels. Since then, system designers and users have distinguished between importance and urgency. In the industrial field, due to the harsh environment they operate in, industrial wireless networks’ quality of service (QoS) has always been a bottleneck restricting their applications. Therefore, this book introduces criticality to label important data, which is then allocated more transmission resources, ensuring that important data’s QoS requirements can be met to the extent possible. To help readers understand how to apply mixed-criticality data to industrial wireless networks, the content is divided into three parts. First, we introduce how to integrate the model of mixed-criticality data into industrial wireless networks. Second, we explain how to analyze the schedulability of mixed-criticality data under existing scheduling algorithms. Third, we present a range of novel scheduling algorithms for mixed-criticality data. If you want to improve the QoS of industrial wireless networks, this book is for you.

Available in PDF, EPUB and Kindle. Book excerpt: The DRAM main memory is a critical component and a performance bottleneck of almost all computing systems. Since the DRAM is a shared memory resource on multi-core plat- forms, all cores contend for the memory bandwidth. Therefore, there is a keen interest in the real-time community to design predictable DRAM controllers to provide a low memory access latency bound to meet the strict timing requirement of real-time applications. Due to the lack of generalization of publicly available DRAM controller models in full-system and DRAM device simulators, researchers often design in-house simulator to validate their designs. An extensible cycle-accurate DRAM controller simulation frame- work is developed to simplify the process of validating new DRAM controller designs. To prove the extensibility and reusability of the framework, ten state-of-the-art predictable DRAM controllers are implemented in the framework with less than 200 lines of new code. With the help of the framework, a comprehensive evaluation of state-of-the-art pre- dictable DRAM controllers is performed analytically and experimentally to show the im- pact of different system parameters. This extensive evaluation allows researchers to assess the contribution of state-of-the-art DRAM controller approaches. At last, a novel DRAM controller with request reordering technique is proposed to provide a configurable trade-off between latency bound and bandwidth in mixed-critical systems. Compared to the state-of-the-art DRAM controller, there is a balance point between the two designs which depends on the locality of the task under analysis and the DRAM device used in the system.

Available in PDF, EPUB and Kindle. Book excerpt: An introduction to the engineering principles of embedded systems, with a focus on modeling, design, and analysis of cyber-physical systems. The most visible use of computers and software is processing information for human consumption. The vast majority of computers in use, however, are much less visible. They run the engine, brakes, seatbelts, airbag, and audio system in your car. They digitally encode your voice and construct a radio signal to send it from your cell phone to a base station. They command robots on a factory floor, power generation in a power plant, processes in a chemical plant, and traffic lights in a city. These less visible computers are called embedded systems, and the software they run is called embedded software. The principal challenges in designing and analyzing embedded systems stem from their interaction with physical processes. This book takes a cyber-physical approach to embedded systems, introducing the engineering concepts underlying embedded systems as a technology and as a subject of study. The focus is on modeling, design, and analysis of cyber-physical systems, which integrate computation, networking, and physical processes. The second edition offers two new chapters, several new exercises, and other improvements. The book can be used as a textbook at the advanced undergraduate or introductory graduate level and as a professional reference for practicing engineers and computer scientists. Readers should have some familiarity with machine structures, computer programming, basic discrete mathematics and algorithms, and signals and systems.

Book excerpt: Principles of Asynchronous Circuit Design - A Systems Perspective addresses the need for an introductory text on asynchronous circuit design. Part I is an 8-chapter tutorial which addresses the most important issues for the beginner, including how to think about asynchronous systems. Part II is a 4-chapter introduction to Balsa, a freely-available synthesis system for asynchronous circuits which will enable the reader to get hands-on experience of designing high-level asynchronous systems. Part III offers a number of examples of state-of-the-art asynchronous systems to illustrate what can be built using asynchronous techniques. The examples range from a complete commercial smart card chip to complex microprocessors. The objective in writing this book has been to enable industrial designers with a background in conventional (clocked) design to be able to understand asynchronous design sufficiently to assess what it has to offer and whether it might be advantageous in their next design task.
