As the number of cores on a chip continues to climb, architects will need to address both bandwidth and power consumption issues related to the interconnection network. Electrical interconnects are not likely to scale well to a large number of processors for energy efficiency reasons, and the problem is compounded by the fact that there is a fixed total power budget for a die, dictated by the amount of heat that can be dissipated without special (and expensive) cooling and packaging techniques. Thus, there is a need to seek alternatives to electrical signaling for on-chip interconnection applications. Photonics, which has a fundamentally different mechanism of signal propagation, offers the potential to not only overcome the drawbacks of electrical signaling, but also enable the architect to build energy efficient, scalable systems. The purpose of this book is to introduce computer architects to the possibilities and challenges of working with photons and designing on-chip photonic interconnection networks.

In recent years, both Networks-on-Chip, as an architectural solution for high-speed interconnect, and power consumption, as a key design constraint, have continued to gain interest in the design and research communities. This book offers a single-source reference to some of the most important design techniques proposed in the context of low-power design for networks-on-chip architectures.

Programmable Logic Devices (PLDs) have become the key implementation medium for the vast majority of digital circuits designed today. While the highest-volume devices are still built with full-fabrication rather than field programmability, the trend towards ever fewer ASICs and more FPGAs is clear. This makes the field of PLD architecture ever more important, as there is stronger demand for faster, smaller, cheaper and lower-power programmable logic. PLDs are 90% routing and 10% logic. This book focuses on that 90% that is the programmable routing: the manner in which the programmable wires are connected and the circuit design of the programmable switches themselves. Anyone seeking to understand the design of an FPGA needs to become lit erate in the complexities of programmable routing architecture. This book builds on the state-of-the-art of programmable interconnect by providing new methods of investigating and measuring interconnect structures, as well as new programmable switch basic circuits. The early portion of this book provides an excellent survey of interconnec tion structures and circuits as they exist today. Lemieux and Lewis then provide a new way to design sparse crossbars as they are used in PLDs, and show that the method works with an empirical validation. This is one of a few routing architecture works that employ analytical methods to deal with the routing archi tecture design. The analysis permits interesting insights not typically possible with the standard empirical approach.

In Interconnect-centric Design for Advanced SoC and NoC, we have tried to create a comprehensive understanding about on-chip interconnect characteristics, design methodologies, layered views on different abstraction levels and finally about applying the interconnect-centric design in system-on-chip design. Traditionally, on-chip communication design has been done using rather ad-hoc and informal approaches that fail to meet some of the challenges posed by next-generation SOC designs, such as performance and throughput, power and energy, reliability, predictability, synchronization, and management of concurrency. To address these challenges, it is critical to take a global view of the communication problem, and decompose it along lines that make it more tractable. We believe that a layered approach similar to that defined by the communication networks community should also be used for on-chip communication design. The design issues are handled on physical and circuit layer, logic and architecture layer, and from system design methodology and tools point of view. Formal communication modeling and refinement is used to bridge the communication layers, and network-centric modeling of multiprocessor on-chip networks and socket-based design will serve the development of platforms for SoC and NoC integration. Interconnect-centric Design for Advanced SoC and NoC is concluded by two application examples: interconnect and memory organization in SoCs for advanced set-top boxes and TV, and a case study in NoC platform design for more generic applications.

Streamlined Design Solutions Specifically for NoC To solve critical network-on-chip (NoC) architecture and design problems related to structure, performance and modularity, engineers generally rely on guidance from the abundance of literature about better-understood system-level interconnection networks. However, on-chip networks present several distinct challenges that require novel and specialized solutions not found in the tried-and-true system-level techniques. A Balanced Analysis of NoC Architecture As the first detailed description of the commercial Spidergon STNoC architecture, Design of Cost-Efficient Interconnect Processing Units: Spidergon STNoC examines the highly regarded, cost-cutting technology that is set to replace well-known shared bus architectures, such as STBus, for demanding multiprocessor system-on-chip (SoC) applications. Employing a balanced, well-organized structure, simple teaching methods, numerous illustrations, and easy-to-understand examples, the authors explain: how the SoC and NoC technology works why developers designed it the way they did the system-level design methodology and tools used to configure the Spidergon STNoC architecture differences in cost structure between NoCs and system-level networks From professionals in computer sciences, electrical engineering, and other related fields, to semiconductor vendors and investors – all readers will appreciate the encyclopedic treatment of background NoC information ranging from CMPs to the basics of interconnection networks. The text introduces innovative system-level design methodology and tools for efficient design space exploration and topology selection. It also provides a wealth of key theoretical and practical MPSoC and NoC topics, such as technological deep sub-micron effects, homogeneous and heterogeneous processor architectures, multicore SoC, interconnect processing units, generic NoC components, and embeddings of common communication patterns.

Recent technology advent makes the efficient on-chip interconnection architecture critical in modern IC design. First, on-chip communication requirements are dramatically increasing due to the continuously shrinking of the device feature size and integration of billions of transistors on a single chip. Second, the interconnects, rather than devices, become the dominant factors in deciding performance and power consumption of VLSI systems. As a result, we are urged to optimize interconnection architecture to improve the overall system performance. In this dissertation, we propose a methodology to optimize the power consumption or communication latency of two promising on-chip interconnection architectures, Network-on-Chip (NoC) and FPGA global routing architecture. Our methodology adopts two optimization schemes, topology optimization and wire style optimization, and uses multicommodity flow (MCF) models to perform and evaluate these optimizations. We implement and optimize the MCF solver using polynomial approximation algorithms, which are significantly faster than the commercial linear programming solver CPLEX. For NoC optimization, our objective is to search for most power efficient NoC topologies and their wire assignments, which at the same time satisfy all communication latency and bandwidth requirements. We use MCF formulations to model this problem, and build NoC topology library and its power and delay library as inputs to MCF formulations. The solution of MCF formulations indicates the estimated NoC power consumption under a certain NoC topology and wire style assignments, from which we can observe the best NoC optimization. The experimental results show that our methodology can effectively improve the NoC power consumption or communication latency. The results also indicate the importance of power and latency co-optimization in NoC design. For FPGA global routing architecture optimization, we study segmentation distribution, flexible track assignment and wire style optimization. The objectives are power consumption and switch area density. The design methodology is also based on MCF formulations. We examine our FGPA routing architecture optimization by a set of standard MCNC benchmark circuits. The experimental results show that our optimized FPGA routing architectures achieve average up to 10% to 15% power savings and up to 20% switch area savings when compared to traditional FPGA architecture.

With the ability to integrate a large number of cores on a single chip, research into on-chip networks to facilitate communication becomes increasingly important. On-chip networks seek to provide a scalable and high-bandwidth communication substrate for multi-core and many-core architectures. High bandwidth and low latency within the on-chip network must be achieved while fitting within tight area and power budgets. In this lecture, we examine various fundamental aspects of on-chip network design and provide the reader with an overview of the current state-of-the-art research in this field.
