英文摘要: Nowadays, the microprocessor market is approaching the many-core era. The number of cores on a single chip increases exponentially. However, the power and the on-chip interconnection problem are still bottlenecks for the continuing developments of the many-core microprocessors. Compared with synchronous circuits, asynchronous circuits have several advantages, e.g, low-power, better EMI, high modularity, etc. Using asynchronous circuits may naturally solve the problems faced today by the designers of many-core microprocessors. It is a certain tend that the asynchronous circuits will be widely used in the future many-core microprocessors. Driven by the problems in the many-core developing progress, we will do the researches on the key techniques of many-core asynchronous microprocessors in this project. Our aim is to combine the power advantage of asynchronous circuits with the abundant computing resources in many-core microprocessors to achieve a high power-efficient microprocessor system. We will mainly focus on the following subjects: high power-efficient many-core microprocessor architecture and computing model; high power-efficient asynchronous circuit design methods; high power-efficient single-core asynchronous microprocessor design; high power-efficient asynchronous network-on-chip; power-efficiency estima
