Abstract

Processing-in-Memory for commodity DRAM systems is starting to emerge with recent commercial offerings. In this talk, we will summarize our experiences in exploring the what, where, and how of such PIM DDR systems. Rather than many prior studies which built custom compute engines, we explore general purpose RISC-V cores near the memory arrays to be useful across a wider spectrum of applications. We will show different options for placing these cores and the associated trade-offs. Finally, we will explore programming and compiler support to offload applications readily onto these platforms.
