Abstract:

Advances in semiconductor manufacturing will permit an unprecedented number of transistors on a single processor die. But what architecture will make  the best use of these riches become a focus. After surveying the research of billion-transistor architectures, we focus on PIM, which integrates the CMOS logic with DRAM memories on the same die, and provide high bandwidth,low latency and low power. PIM makes the best use of giant on-chip budget, but al so relaxes the eager memory-wall, power,and wire latency. Coupled with the vector processing logic, PIM can expose the advantages in itself.

Key words: （billion-transistor architecture, memory wall, vector processing, Processor-in-Memory）
