英文摘要： In order to meet the ever increasing demand for high performance computing power, it is inevitable to integrate more and more cores on a single chip to form many-core chip multiprocessor (CMP). CMPs have been widely used in cloud computing, mobile devices, high performance computing etc. The increasing of the chip performance, however, comes with explosive growth in power consumption, preventing it from further growth in CMP performance. This project mainly studies the key issues of energy-efficient network-on-chip (NoC) in architectural level. The major topics include research on the energy-efficient heterogeneous NoC architecture; design of routing protocol and router architecture in multiple NoCs; studying the related network congestion metric, propagation and collection mechanism of congestion information;establishing energy-efficient multiple NoC model, power model, and the trade-off mechanism between power-gating and network performance. The main purpose is to study and explore the new theory and methods in building energy-efficient multiple network-on-chip (NoC) in many-core CMPs.
