While heterogeneous CPU/GPU systems have been traditionally implemented on separate chips, each with their own private DRAM, heterogeneous processors are integrating these different core types on the same die with access to a common physical memory. Further, emerging heterogeneous CPU-GPU processors promise to offer tighter coupling between core types via a unified virtual address space and cache coherence. To adequately address the potential opportunities and pitfalls that may arise from thisdoi:10.1109/iiswc.2014.6983054 dblp:conf/iiswc/HestnessKW14 fatcat:k76obdosvfhi5aftguivbbyhbe
