“…For NVIDIA Pascal [57], more than 60% of the on-chip storage area, amounting to 14.3 MB is dedicated to the register file. GPU register files face the difficult challenge of optimizing latency, bandwidth, and power consumption, while having maximal capacity [2,19,20,23,25,27,28,39,43,45,46,48,65,66,78,79,80]. Larger register files are slower, take up more silicon area and consume more power.…”
