Experimental Partnership - FlexRAM: An Advanced Intelligent Memory System

EIA-0072102 Josep Torrellas大学伊利诺伊州-香槟标题：实验伙伴关系：FlexRAM：一种先进的智能存储器系统可集成在单个芯片上的晶体管数量的急剧增加使微处理器性能和存储器芯片容量都有了显著的提高。 然而，它们也导致了处理器和存储器系统之间日益约束的数据传输瓶颈。 认识到需要新的架构方法来缓解这一瓶颈，研究人员提出了在单个芯片中集成处理器和DRAM。 这种架构通常被称为智能存储器（IRAM）或内存中处理器（PIM）。不幸的是，将当前的微处理器和DRAM简单集成在单个芯片上通常只能带来适度的性能改进-它将芯片上的芯片外瓶颈移动。 此外，由此产生的系统通常很难编程。 最后，很少有人投入精力来尝试识别可以有效利用这种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.
