New DRAMPower Paper at HiPEAC's Rapido Workshop
12/17/2024As off-chip memory accesses nowadays dominate the overall power consumption of many compute platforms, accurate DRAM power simulation models are an important tool for system designers. Unfortunately, existing open-source models only support older generations of DRAM standards, while current system designs mainly rely on the newest generation including DDR5, LPDDR5 or HBM3.
In addition, the existing models are not directly applicable to the new standards because of the much higher data rates and newly introduced features. This paper presents DRAMPower 5, a completely revised version of the popular DRAMPower simulator, which uses newly developed core and interface power models to support the current generation of DRAM standards. In addition, DRAMPower 5 features a redesigned software architecture that enables both fast and accurate simulation. The tool is open source and available on GitHub.
