SUMMARY:OpenMem: Hardware/Software Cooperative Management for Mobile Memor
 y System
DESCRIPTION:Research Manuscript\n\nOpenMem: Hardware/Software Cooperative 
 Management for Mobile Memory System\n\nGratz, Wen\n\nHybrid memory, compri
 sed of non-volatile memory and DRAM, is promising to provide larger memory
  capacity with less static power consumption. This work proposed a hardwar
 e/software cooperative management for mobile memory system. The hardware-b
 ased memory controller learns short-term access patterns by online profili
 ng, and executes data migration efficiently. The software memory allocator
  accepts programmer's hints of favorable memory device for data objects' a
 llocation, and presumed object life cycle. We implemented the system on th
 e ARM-embedded FPGA and ran benchmark applications from SPEC 2017 and PARS
 EC. Experiment results show that OpenMem reduces 44.6% energy consumption 
 and 14% NVM writes, extending device lifetime.\n\nTopic: Embedded Systems\
