A layered architecture called Network-on-Chip (NoC) has been recently proposed for global communication in a complex System-on-Chip (SoC) design to meet the performance requirements, and many new design and testing issues come up correspondingly. In this work, we aim to develop an efficient test strategy for NoC embedded core testing with a high performance router architecture which can support normal mode as well as testing mode operations. For normal mode router design, we propose to use a novel dynamic XY (namely DyXY) routing method, which provides adaptive routing based on congestion conditions in the proximity, and ensures deadlock-free and livelock-free features at the same time. Analytical models based on queuing theory are developed for DyXY routing in two-dimensional mesh architectures, and analytical results match very much with the simulation results. It is observed that DyXY routing can achieve much better performance when compared with static XY routing and odd-even routing. Hardware is also designed to support the DyXY routing method efficiently. For embedded core testing, we propose a multiple-data-flit-format (MDFF) test data transportation concept, a heuristic wrapper scan chain configuration method, and a test scheduling algorithm which considers both channel capacity and flit interleaving in the channels and routers. By applying the proposed test scheduling method together with the MDFF concept and the heuristic scan chain configuration method, the on-chip network channel of a NoC can be fully utilized for embedded core testing, the test time for the entire NoC can be minimized, and the test power dissipation can be controlled well. By comparing the results with other published works, it has been demonstrated that the proposed test scheduling method can achieve significant improvement on the test time for the entire NoC. To support the proposed embedded core testing strategy, design issues for testing mode operations have also been explored, and a complete router architecture is presented to support both normal mode (DyXY) and test mode operations. With all these works completed, we have an efficient NoC embedded core testing strategy with the support of a router architecture which provides high performances in test mode and normal mode operations.

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.

The aggressive scaling of the semiconductor technology following the Moore's Law has delivered true system-on-chip (SoC) integration. Network-on-chip (NoC) has been recently introduced as an effective solution for scalable on-chip communication since dedicated point-to-point (P2P) interconnection and shared bus architecture become performance and power bottlenecks in the SoCs. This dissertation studies three critical NoC challenges such as latency, power, and compatibility with emerging technologies in aspect of an architecture and physical design level. Latency is a key issue in NoC since the performance of applications considerably depends on resource sharing policies employed in an on-chip network. NoCs have been mainly developed to improve network-level performance that captures the inherent performance characteristics of a network itself, but the network-level optimizations are not directly related to application- or system-level performance. In addition, memory latency on NoC critically affects the performance of applications or systems. We propose a synchronous dynamic random access memory (SDRAM) aware NoC design to optimize memory throughput, latency, and design complexity. Furthermore, it is extended to an application-aware NoC design to provide the quality-of-service (QoS) of memory for various applications. NoC provides great on-chip communication. However, it brings no true relief to power budget when the on-chip network scales in terms of complexity/size and signal bandwidth. The combination of NoC and other techniques has the potential to reduce power. We study two power saving research topics for NoC: (a) we propose a voltage-frequency island (VFI) aware NoC optimization framework with a better tradeoff between power efficiency and design complexity to minimize both computation and on-chip communication power. (b) We formulate an application mapping problem to mixed integer quadratic programming (MIQP) with the purpose of reducing power consumption in various hard networks and develop highly efficient algorithms for the MIQP. Regarding NoC compatible with new technologies, we focus on three dimensional (3D) die integration based on through-silicon vias (TSVs). Since an on-chip network design has been subject to not only application constraints but also design/manufacturing constraints, a 3D NoC design is required for innovation in interconnection networks. We propose a chemical-mechanical polishing (CMP) aware application-specific 3D NoC design that minimizes TSV height variation, thus reduces bonding failure, and meanwhile optimizes conventional NoC design objectives such as hop count, wirelength, power, and area.

[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.

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.
