Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "The benefits of a behavioral synthesis design methodology, including higher designer productivity and shorter time-to- market, are the results of allowing the designer to use more abstract and familiar specifications. One of the most common and familiar abstractions used by hardware and software designers is the array, which allows the specification of a set of values that have a unique index associated with each element. A behavioral synthesis tool that accepts specifications containing arrays must map the storage implied by the arrays to memory in an implementation of that specification. In many data-intensive applications, these memory design decisions have a larger impact on the cost, performance, and power of the implementation than any other design decision made by a behavioral synthesis tool. Most behavioral synthesis tools, however, fail to separate the concepts of array specification and memory implementation, which severely restricts the span of designs that can be explored given a behavioral specification. This thesis describes a new tool in a behavioral synthesis system, named ASSASYN, that creates memory designs according to the semantics of the behavioral specification and a set of user-specified design goals. ASSASYN's approach is based on the observation that both arrays and memory components are rectangular arrangements of bits. The creation of an array-memory mapping is therefore a rectangular placement problem. Because the tasks of array-memory mapping and scheduling are highly interdependent, ASSASYN simultaneously optimizes the array-memory mapping and the array access schedule. This approach to creating a memory design is more general and effective than any previously published approach. Other novel contributions of this research include fast and inexpensive techniques for address generation and synthesis timing models for both static and dynamic memory components. Five different data-intensive applications have been used to demonstrate the effectiveness of this approach. For each application, ASSASYN was used to generate a set of implementations that span a wide range of memory cost, memory power and performance characteristics. Compared to related research efforts in memory design, ASSASYN generated designs with up to 19% better performance, up to 40% less memory cost, and up to 57% fewer wires between the memory system and the data path."

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a structured introduction of the key concepts and techniques that enable in-/near-memory computing. For decades, processing-in-memory or near-memory computing has been attracting growing interest due to its potential to break the memory wall. Near-memory computing moves compute logic near the memory, and thereby reduces data movement. Recent work has also shown that certain memories can morph themselves into compute units by exploiting the physical properties of the memory cells, enabling in-situ computing in the memory array. While in- and near-memory computing can circumvent overheads related to data movement, it comes at the cost of restricted flexibility of data representation and computation, design challenges of compute capable memories, and difficulty in system and software integration. Therefore, wide deployment of in-/near-memory computing cannot be accomplished without techniques that enable efficient mapping of data-intensive applications to such devices, without sacrificing accuracy or increasing hardware costs excessively. This book describes various memory substrates amenable to in- and near-memory computing, architectural approaches for designing efficient and reliable computing devices, and opportunities for in-/near-memory acceleration of different classes of applications.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "This paper discusses the mapping of arrays in a behavior to memories in an implementation. We introduce a novel approach to the design of memory systems, which is based on a variety of array grouping techniques and dimensional transformations, and the binding of array groups to memory components with different dimensions, access times, and number of ports. The results of design actions are computed in terms of memory cost, the number of wires necessary to connect the memory to the data path, and the limit of performance imposed by the memory design on the implementation. Three different procedures can be used to find a suitable memory design. All three procedures are directed by a weighted and constrained system cost function, which enables the expression of the user's design priorities. Compared to related research efforts, our approach improves performance by as much as 19%, reduces memory cost by as much as 40%, and decreases the number of wires required to connect the memory to the data path by up to 57%."

This book was released on 2012-12-06 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Application-Driven Architecture Synthesis describes the state of the art of architectural synthesis for complex real-time processing. In order to deal with the stringent timing requirements and the intricacies of complex real-time signal and data processing, target architecture styles and target application domains have been adopted to make the synthesis approach feasible. These approaches are also heavily application-driven, which is illustrated by many realistic demonstrations, used as examples in the book. The focus is on domains where application-specific solutions are attractive, such as significant parts of audio, telecom, instrumentation, speech, robotics, medical and automotive processing, image and video processing, TV, multi-media, radar, sonar. Application-Driven Architecture Synthesis is of interest to both academics and senior design engineers and CAD managers in industry. It provides an excellent overview of what capabilities to expect from future practical design tools, and includes an extensive bibliography.

Available in PDF, EPUB and Kindle. Book excerpt: This is a tour through recent and prominent works regarding new DRAM chip designs and technologies, near data processing approaches, new memory channel architectures, techniques to tolerate the overheads of refresh and fault tolerance, security attacks and mitigations, and memory scheduling. The memory system will soon be a hub for future innovation. While conventional memory systems focused primarily on high density, other memory system metrics like energy, security, and reliability are grabbing modern research headlines. With processor performance stagnating, it is also time to consider new programming models that move some application computations into the memory system. This, in turn, will lead to feature-rich memory systems with new interfaces. The past decade has seen a number of memory system innovations that point to this future where the memory system will be much more than dense rows of unintelligent bits.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents novel compiler techniques, which combine a rigorous mathematical framework, novel program analyses and digital hardware design to advance current high-level synthesis tools and extend their scope beyond the industrial ‘state of the art’. Implementing computation on customised digital hardware plays an increasingly important role in the quest for energy-efficient high-performance computing. Field-programmable gate arrays (FPGAs) gain efficiency by encoding the computing task into the chip’s physical circuitry and are gaining rapidly increasing importance in the processor market, especially after recent announcements of large-scale deployments in the data centre. This is driving, more than ever, the demand for higher design entry abstraction levels, such as the automatic circuit synthesis from high-level languages (high-level synthesis). The techniques in this book apply formal reasoning to high-level synthesis in the context of demonstrably practical applications. /pp

Download or read book A Primer on Memory Consistency and Cache Coherence written by Daniel Sorin and published by Morgan & Claypool Publishers. This book was released on 2011-03-02 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many modern computer systems and most multicore chips (chip multiprocessors) support shared memory in hardware. In a shared memory system, each of the processor cores may read and write to a single shared address space. For a shared memory machine, the memory consistency model defines the architecturally visible behavior of its memory system. Consistency definitions provide rules about loads and stores (or memory reads and writes) and how they act upon memory. As part of supporting a memory consistency model, many machines also provide cache coherence protocols that ensure that multiple cached copies of data are kept up-to-date. The goal of this primer is to provide readers with a basic understanding of consistency and coherence. This understanding includes both the issues that must be solved as well as a variety of solutions. We present both highlevel concepts as well as specific, concrete examples from real-world systems. Table of Contents: Preface / Introduction to Consistency and Coherence / Coherence Basics / Memory Consistency Motivation and Sequential Consistency / Total Store Order and the x86 Memory Model / Relaxed Memory Consistency / Coherence Protocols / Snooping Coherence Protocols / Directory Coherence Protocols / Advanced Topics in Coherence / Author Biographies
Download or read book Multi Core Cache Hierarchies written by Rajeev Balasubramonian and published by Springer Nature. This book was released on 2022-06-01 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: A key determinant of overall system performance and power dissipation is the cache hierarchy since access to off-chip memory consumes many more cycles and energy than on-chip accesses. In addition, multi-core processors are expected to place ever higher bandwidth demands on the memory system. All these issues make it important to avoid off-chip memory access by improving the efficiency of the on-chip cache. Future multi-core processors will have many large cache banks connected by a network and shared by many cores. Hence, many important problems must be solved: cache resources must be allocated across many cores, data must be placed in cache banks that are near the accessing core, and the most important data must be identified for retention. Finally, difficulties in scaling existing technologies require adapting to and exploiting new technology constraints. The book attempts a synthesis of recent cache research that has focused on innovations for multi-core processors. It is an excellent starting point for early-stage graduate students, researchers, and practitioners who wish to understand the landscape of recent cache research. The book is suitable as a reference for advanced computer architecture classes as well as for experienced researchers and VLSI engineers.

Download or read book Customizable Computing written by Yu-Ting Chen and published by Springer Nature. This book was released on 2022-05-31 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the end of Dennard scaling in the early 2000s, improving the energy efficiency of computation has been the main concern of the research community and industry. The large energy efficiency gap between general-purpose processors and application-specific integrated circuits (ASICs) motivates the exploration of customizable architectures, where one can adapt the architecture to the workload. In this Synthesis lecture, we present an overview and introduction of the recent developments on energy-efficient customizable architectures, including customizable cores and accelerators, on-chip memory customization, and interconnect optimization. In addition to a discussion of the general techniques and classification of different approaches used in each area, we also highlight and illustrate some of the most successful design examples in each category and discuss their impact on performance and energy efficiency. We hope that this work captures the state-of-the-art research and development on customizable architectures and serves as a useful reference basis for further research, design, and implementation for large-scale deployment in future computing systems.
