中文摘要： 在众多高效能计算需求领域，可重构技术以其极为卓越的性能而被寄予厚望，成为超越传统计算架构的重要手段。然而，随着可重构系统资源大规模化、异构化的发展趋势，一些关键基础问题，例如大规模可重构系统计算模型、体系结构一体化设计及管理、非对称性难题等等，极大限制了可重构计算的发展和应用。新兴的流计算模型以存储与计算解耦合、计算密集化、数据规则化和高预知性等特点，为可重构计算的发展提供了新的思路。本课题对流计算模型进行创新并引入到可重构计算中，首次提出大规模非对称可重构流计算理论与技术研究，引入了多态可重构计算模型和与之相匹配的可重构流体系结构模板，并基于共有模型和模板对可重构系统进行软硬件协同管理，支持面向应用快速构建和优化可重构平台，提高可重构系统实际计算效能。该项研究具有原创性，对我国发展面向大规模数字信号处理、科学模拟以及其它特殊领域的高效能计算平台具有重要意义。

英文摘要： In many domains with high requirments for high performance efficiency, reconfigurable computing is becoming an important approach to overcome traditional computing infrastructure due to outstanding performance. However, as the scale of reconfigurable system is increasing and heterogeneous computing systems is becoming mainstream, some key issues, such as compute model of large scale reconfigurable system, uniform architecture design and management,problems incured by asymmetric units et al., limit reconfiguable computing's progress and application extremely. Emerging stream compute model provide a new progress space for reconfigurable computing due to decoupling computation and load/store,exposing data level parallelism,data regularization,and high predictability. This project introduces stream compute model into reconfigurable computing. We present reconfigurable stream computing theory and technology research on the large-scale asymmetrical system. On the basis of multi-morph reconfigurable compute model and reconfigurable stream architecture template, the reconfigurable system can be quickly constructed for some special application, while hardware-software collaborative management can be used to optimize and improve the real computation efficiency. The research has creativity. It would benefit for developin
