Available in PDF, EPUB and Kindle. Book excerpt: Future system-on-chip (SoC) designs require predictable, scalable and reusable on-chip interconnect architecture to increase reliability and productivity. Current bus-based interconnect architectures are inherently non-scalable, less adaptable for reuse and their reliability decreases with system size. To overcome these problems, it has been proposed to build a message passing network for on-chip communication - network-on-chip (NoC). We aim to develop a performance analysis model for the on-chip communication of a NoC system. We will use a stochastic modeling technique for performance analysis of the on-chip communication network. In our approach, the analytic model is developed using queuing theory. The router of a NoC system consists of buffers with different quality of service (QoS). The buffers can be modeled as priority queues. Their performance can be analyzed using the principles of queuing theory. The analytical results thus calculated are verified with the corresponding simulation results.

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.

This book was released on 2013-03-12 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, design space exploration for Systems-on-Chip (SoCs) has focused on the computational aspects of the problem at hand. However, as the number of components on a single chip and their performance continue to increase, the communication architecture plays a major role in the area, performance and energy consumption of the overall system. As a result, a shift from computation-based to communication-based design becomes mandatory. Towards this end, network-on-chip (NoC) communication architectures have emerged recently as a promising alternative to classical bus and point-to-point communication architectures. In this dissertation, we study outstanding research problems related to modeling, analysis and optimization of NoC communication architectures. More precisely, we present novel design methodologies, software tools and FPGA prototypes to aid the design of application-specific NoCs.

Available in PDF, EPUB and Kindle. Book excerpt: Technology scaling has driven multi-core development inside a chip. On-chip interconnect implementation becomes one of the major challenges when considering large scale of VLSI designs. Although bus architecture has prevailed for the past decade, it no longer can fulfill the stringent application requirements for designs with hundreds of cores. Therefore Network-on-Chip (NoC) architecture is proposed as a unified solution to tackle interconnection design problems. This dissertation proposed two innovative NoC architectures, DMesh and WNoC, to improve transmission performance, energy dissipation and network throughput. DMesh deployed diagonal channels adopts a quasi-minimal adaptive routing algorithm to balance traffic load and prevent congestion for a two-dimensional mesh network. A low-cost scalable congestion-aware mechanism was devised to resolve load imbalance and increase traffic accommodation. Significant performance improvement can be observed from simulation results. To further augment resource utilization efficiency, QoS provision was equipped to support differentiated service for versatile applications. QoS-aware router design was realized and synthesized to estimate implementation overhead in terms of area and power consumption. Furthermore, power-aware design was achieved by introducing a statistical power model. Experimental results have shown that transfer latency and throughput are greatly improved and overall system power dissipation is also decreased by the insertion of diagonal links. As hundreds or thousands of cores are integrated inside a chip, long distance communication and energy dissipation become more critical issues for designing interconnection networks. A hybrid infrastructure which incorporates on-chip wireless interconnect along with existing wired NoC was proposed. Customized wireless link insertion algorithm was studied. Simulated annealing optimization technique was employed to decide placement for wireless routers in order to minimize transmission time. Congestion management utilizing both global and local network conditions to make routing decision was devised. Balanced traffic helped to prevent congestion situations and enhanced network bandwidth utilization. Performance evaluation and feasibility analysis have demonstrated the proposed approach as a promising solution to deal with wide ranges of communication tasks.

This book was released on 2015-12-16 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes in detail the impact of process variations on Network-on-Chip (NoC) performance. The authors evaluate various NoC topologies under high process variation and explain the design of efficient NoCs, with advanced technologies. The discussion includes variation in logic and interconnect, in order to evaluate the delay and throughput variation with different NoC topologies. The authors describe an asynchronous router, as a robust design to mitigate the impact of process variation in NoCs and the performance of different routing algorithms is determined with/without process variation for various traffic patterns. Additionally, a novel Process variation Delay and Congestion aware Routing algorithm (PDCR) is described for asynchronous NoC design, which outperforms different adaptive routing algorithms in the average delay and saturation throughput for various traffic patterns.
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.
Download or read book Performance Evaluation of Cache based Multi core Architectures with Networks on chip written by Robin Kingsley Rajkumar and published by . This book was released on 2012 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-core architectures are the future for high-performance computing and are omnipresent these days; what was a vision some twenty years back is now a reality with most personal computers/laptops now running on multi-cores making them ubiquitous in today's world. However, as the number of cores continue scaling with time, there will be serious throughput and performance issues with relation to the network topologies used in connecting the cores. Among possible network topologies under consideration in modern multi-core systems, the 'Mesh' topology is widely used. In terms of performance, the 'Point to Point topology' would outperform all other topologies such as Crossbar, Mesh and Torus. The 'Point to Point' topology does include additional expenses with respect to more links needed to connect each core to every other core in the network. Its expensive implementation cost is the reason it is not preferred in the industry for general use systems. But, for research purposes it serves as the best network topology alternative to the 'Mesh' for higher speed in computer systems. However, the characteristics of the tasks executing on the cores will also have a significant impact on topology performance. So, with the scaling of multi-cores from 10 to 1000 cores per chip and more, selection of the right network topology is of importance. Another interesting factor to consider is the effect of the cache on these multi-core systems with respect to each of these topologies. Cache coherency is and will be a major cause for throughput decrease as cores scale. In our work, we are using the Modified-Exclusive-Shared-Invalid (MESI) Cache Coherency protocol for all the above mentioned network topologies considered. In this thesis, the author investigates the effect of varying cache parameters such as the sizes of L1 Instruction cache, L1 Data cache and L2 cache and their respective associativities on each network topology. Various combinations of all these four parameters were considered as the author ran experiments.
