The Research Of Architecture And Key Communication Technology In Network On Chip

Network on Chip (NOC) is one of the most important technologies in current multi-processor systems. The research of its architecture and key communication technologies has become the important method to settle the problem of communication bottle neck. With the development and progress of the related technologies, NOC has taken the place of the traditional bus structure in a certain extent and becomes the focus and advanced technology in the related fields.Based on the previous researches, this paper studies the NOC architecture and its key communication technologies under the support of National Natural Science Fundation of China (60575031). In this paper, the architecture and related technologies of NOC are analyzed in details. The NOC applications and the communication problems among IPs (processors) are deeply researched. Some novel and practical results are also gained in this paper. The major content of this paper shows as follows.1. The research of NOC topologies. Discuss the NOC topologies based on the Mesh and Torus, and analyze their performance. Propose the Multi-Dimension Plane (MDP) NOC and Color Domain Hop (CDH) NOC, and compare the performance among different NOC topologies.2. The research of the microarchitecture of NOC router. Study the structure of current NOC router and improve its performance. Propose the novel microarchitecture of NOC router, including the double buffer router and customized arbitral priority router.3. The research of the optimization problem in NOC communication. For the communication delay among NOC IPs, this paper gives the train of optimization thought and proposes the solutions. There are three different methods, including the dual-mode NOC communication structure, the data transmission mode of binding ID numbers and one strategy of optimizing the NOC resources.4. With the SystemC language, we design and implement the tool of NOC simulation and verification—NSVP (NOC Simulation and Verification Platform).5. We implement the NOC hardware emulation and evaluation platform. Introduce the design methods of hardware-software cooperation platform. Implement the NOC hardware platform and give the evaluation results.The NOC technology has become one of the most important aspects in current communication on chip. Its major purposes are driving the development of the multi-processor system, improving the integration and complexity of communication system, and enhancing the parallel processing capability of on-chip systems. The main innovation points of this paper are shown as follows.1. Improve the current direct NOC topologies. Propose the novel structures, which are suited for more scalable and complex NOC, and evaluate their performance.2. Based on the implementation of different microarchitecture of NOC router, propose the improving method of the router structure and arbitration mode. Use the novel router to some specific applications and gain the evaluation results of the performance.3. In the aspects of the NOC structure, data transmission mode and resource allocation strategy, this paper introduces three methods to optimize the communication delay among different NOC IPs.4. Design the software tool for NOC simulation and verification.5. Build the hardware emulation platform for NOC applications.
