Eyeriss: A Spatial Architecture for Energy-Efficient ...
people.csail.mit.eduTo evaluate energy consumption, we categorize the data movements in a spatial architecture into several levels of hierarchy according to their energy cost, and then analyze each dataflow to assess the data movement at each level. This analysis framework provides insights into how each dataflow exploits different types of data movement using
