CAREER: Care and Feeding of High-Performance Processors with Reconfigurable Memory Systems

* 9733475冲微处理器性能的增长速度持续快于内存性能，使计算机系统面临内存瓶颈。 这个项目的目标是在内存系统中分配逻辑，以便在内存系统中执行某些计算，而无需将数据传输到处理器。通过将现场可编程门阵列和存储器集成在同一片芯片上，可以在运行时将细粒度数据处理的计算分配到存储器系统中，从而加快特定应用的速度，其中一个关键的研究问题是如何将计算在高性能处理器和分布式逻辑之间进行划分。该项目正在研究这种分区在一系列应用中的应用，包括用于编译器寄存器分配的整数编程，用于图像和视频编辑的过滤器，互联网路由，用于入侵检测的图匹配以及蛋白质序列匹配。 教育计划包括更新现有的几门计算机体系结构课程，开发新的可重构计算课程，以及将本科生研究纳入该项目。 该项目的预期成果包括设计可重构存储器系统并将其用于计算的方法，仿真工具和硬件原型的基础设施，在应用程序驱动的系统设计中接受培训的学生，以及基于Web的教育软件，以支持计算机体系结构中的协作项目。 ***

*** 9733475 Chong Microprocessor performance continues to increase faster than memory performance, so that computer systems face a memory bottleneck. The goal of this project is to distribute logic within memory systems so that some computations can be performed in the memory system without transferring data to the processor. By fabricating field-programmable gate arrays and memory on the same chip, computations for fine-grained data manipulation can be distributed to the memory system at run time to speed up specific applications.A crucial research issue in such a design is the partitioning of computations between high-performance processors and the distributed logic. This project is investigating this partitioning on a range of appilications, including integer programming for compiler register allocation, filters for image and video editing, internet routing, graph matching for intrusion detection, and protein sequence matching. Educational plans include the updating of several existing courses in computer architecture, the development of new courses in reconfigurable computing, and the incorporation of undergraduate research into the project. Expected outcomes of this project include a methodology for designing reconfigurable memory systems and using them in computations, an infrastructure of simulation tools and hardware prototypes, students trained in applications-driven system design, and web-based educational software to support collaborative projects in computer architecture. ***
