Available in PDF, EPUB and Kindle. Book excerpt: Large on-chip caches are the next big thing in the field of multiprocessors. Extensive research has gone into modeling memory cells and designing performance enhanced cache banks, but now is the time to shift our focus towards interconnects, which seem to dominate the proceedings with the continuous shrinkage observed in process technology. As we move down into deep sub-micron technology, the interconnect parameters begin to hinder the advancements in cache utilization. It is important to address this issue by coming up with new interconnection architectures for caches which help us improve the performance in terms of latency, power and throughput of the system. Apart from network on chip and the hybrid architectures presented in earlier works, we propose new on-chip communication architectures and perform mathematical analysis for these new architectures to determine the latency and energy. Further, these mathematical expressions help us explore and bring out a comparative study of these architectures.

This book was released on 2009 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continual shrinking of process technologies enables many cores and large caches to be incorporated into future chips. Recent research at Intel suggests that a single chip with hundreds of cores is possible in the near future with the possibility of allocating an entire die for on-chip caches [6]. The ever increasing sizes of on-chip caches and the growing domination of wire delay as the technology shrinks necessitates significant changes to traditional cache architectures. Recently proposed non-uniform cache architectures employ a packet switched on-chip network between banks that yields access times that are a function of where data blocks are found. As the network delay and power are major limiting factors affecting the performance and power of large caches, focus on interconnect network design and its influence on NUCA performance and power is essential. In this research, we focus on minimizing the latency and power overhead of the network by introducing heterogeneity within the cache inter-bank network. Instead of associating a router to every cache bank as in generic-NoC architectures, we introduce a hybrid-NoC architecture which employs variable number of routers and a shared bus architecture to interconnect NUCA cache banks. Also, by introducing segmentation to a shared bus we are further able to minimize latency and power overhead of the network. CACTI cache simulator is extended to support NUCA modeling with hybrid-NoC topology and its performance and power consumption are analyzed. Network contention plays a non-trivial role in determining the performance of an on-chip network in a CMP environment. We also augment the performance analysis between grid and hybrid topologies with empirical date on network contention, modeled using the multiprocessor simulator GEMS-Ruby. Our simulation results using benchmark programs and the tools such as CACTI and GEMS-Ruby demonstrate that the proposed hybrid-NoC structure has better performance and power consumption over the generic-NoC structure.

Download or read book Network-on-Chip Architectures written by Chrysostomos Nicopoulos and published by Springer Science & Business Media. This book was released on 2009-09-18 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: [2]. The Cell Processor from Sony, Toshiba and IBM (STI) [3], and the Sun UltraSPARC T1 (formerly codenamed Niagara) [4] signal the growing popularity of such systems. Furthermore, Intel’s very recently announced 80-core TeraFLOP chip [5] exemplifies the irreversible march toward many-core systems with tens or even hundreds of processing elements. 1.2 The Dawn of the Communication-Centric Revolution The multi-core thrust has ushered the gradual displacement of the computati- centric design model by a more communication-centric approach [6]. The large, sophisticated monolithic modules are giving way to several smaller, simpler p- cessing elements working in tandem. This trend has led to a surge in the popularity of multi-core systems, which typically manifest themselves in two distinct incarnations: heterogeneous Multi-Processor Systems-on-Chip (MPSoC) and homogeneous Chip Multi-Processors (CMP). The SoC philosophy revolves around the technique of Platform-Based Design (PBD) [7], which advocates the reuse of Intellectual Property (IP) cores in flexible design templates that can be customized accordingly to satisfy the demands of particular implementations. The appeal of such a modular approach lies in the substantially reduced Time-To- Market (TTM) incubation period, which is a direct outcome of lower circuit complexity and reduced design effort. The whole system can now be viewed as a diverse collection of pre-existing IP components integrated on a single die.
Book Synopsis Design and Analysis of Location Cache in a Network-on-chip Based Multiprocessor System by : Divya Ramakrishnan
Download or read book Design and Analysis of Location Cache in a Network-on-chip Based Multiprocessor System written by Divya Ramakrishnan and published by . This book was released on 2009 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the direction of research to improve the performance of computing systems is focused toward chip multiprocessor (CMP) designs with multiple cores and shared caches integrated on a single chip. To meet the increased demand for data, large on-chip caches are being embedded on the chip, shared between the multiple cores. The traditional bus-based interconnect architectures are non-scalable for large caches and cannot support the higher cache demand from multiple cores, which motivates the design of a network-on-chip (NoC) interconnect structure for shared non-uniform cache architecture (NUCA). The concept of NUCA caches proposes the division of the cache into multiple banks connected by a switched network that can support the simultaneous transport of multiple packets. The larger on-chip cache designs also result in higher power consumption which is a serious concern as fabrication scales down to the nano-technologies. This research focuses on the implementation of the location cache design in a NoC-based NUCA system with multiple cores, in combination with low-leakage L2 cache based on the gated-ground technique. This system architecture helps to reduce the power of L2 cache along with the performance benefit of the on-chip network. The CMP cache system is implemented on a NoC-NUCA framework with a write-through coherency protocol. The features of CACTI and GEMS are extended to support a complete power and performance estimation of the system. A full-system simulation is performed on scientific and multimedia workloads to characterize the NoC-based system. An analysis of the power and performance of the proposed system is presented in comparison with the traditional cache structure in different configurations. The simulation results show that the NoC-based system with the location cache results in significantly saving the energy of the cache system over the traditional bus-based system in any configuration and also the NoC-based system without a location cache. The system also provides better performance compared to a bus-based system, emphasizing the need to shift to a network-based cache interconnect design which can scale to a large number of cores.

Book Synopsis Efficient Processing of Deep Neural Networks by : Vivienne Sze
Download or read book Efficient Processing of Deep Neural Networks written by Vivienne Sze and published by Springer Nature. This book was released on 2022-05-31 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a structured treatment of the key principles and techniques for enabling efficient processing of deep neural networks (DNNs). DNNs are currently widely used for many artificial intelligence (AI) applications, including computer vision, speech recognition, and robotics. While DNNs deliver state-of-the-art accuracy on many AI tasks, it comes at the cost of high computational complexity. Therefore, techniques that enable efficient processing of deep neural networks to improve key metrics—such as energy-efficiency, throughput, and latency—without sacrificing accuracy or increasing hardware costs are critical to enabling the wide deployment of DNNs in AI systems. The book includes background on DNN processing; a description and taxonomy of hardware architectural approaches for designing DNN accelerators; key metrics for evaluating and comparing different designs; features of DNN processing that are amenable to hardware/algorithm co-design to improve energy efficiency and throughput; and opportunities for applying new technologies. Readers will find a structured introduction to the field as well as formalization and organization of key concepts from contemporary work that provide insights that may spark new ideas.
Download or read book Networks on Chip written by Axel Jantsch and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the number of processor cores and IP blocks integrated on a single chip is steadily growing, a systematic approach to design the communication infrastructure becomes necessary. Different variants of packed switched on-chip networks have been proposed by several groups during the past two years. This book summarizes the state of the art of these efforts and discusses the major issues from the physical integration to architecture to operating systems and application interfaces. It also provides a guideline and vision about the direction this field is moving to. Moreover, the book outlines the consequences of adopting design platforms based on packet switched network. The consequences may in fact be far reaching because many of the topics of distributed systems, distributed real-time systems, fault tolerant systems, parallel computer architecture, parallel programming as well as traditional system-on-chip issues will appear relevant but within the constraints of a single chip VLSI implementation.
