Experimental Partnership - FlexRAM: An Advanced Intelligent Memory System

eia - 0072102约瑟TorrellasUniv。题目：实验合作伙伴关系：FlexRAM：一种先进的智能存储系统可以集成在单个芯片上的晶体管数量的急剧增加使得微处理器性能和存储芯片容量都有了惊人的提高。然而，它们也导致处理器和存储系统之间的数据传输瓶颈日益受限。认识到需要新的架构方法来缓解这一瓶颈，研究人员提出将处理器和DRAM集成到单个芯片中。这种架构通常被称为智能内存（IRAM）或内存中处理器（PIM）。不幸的是，将当前的微处理器和DRAM简单地集成在一个芯片上，往往只能带来有限的性能改进——它在芯片上移动了芯片外的瓶颈。此外，生成的系统通常很难编程。最后，很少投入精力来尝试确定能够有效利用此体系结构的广泛应用程序。

However, they have also led to an increasingly constraining data transfer bottleneck between processor and memory system. Recognizing the need for new architectural approaches that alleviate this bottleneck, researchers have proposed the integration of processor and DRAM in a single chip. This architecture is popularly known as intelligent memory (IRAM) or processor-in-memory (PIM).Unfortunately, simple integration of current microprocessors and DRAM on a single chip often delivers only modest performance improvements-it moves an off-chip bottleneck on chip. Furthermore, the resulting system is often very hard to program. Finally, Little effort has been invested trying to identify a wide range of applications that can exploit this architecture effectively.
