Abstract
As Dennard's scaling stops mainly due to supply voltage limits, power densities rapidly increase on the chip. Hence, a significant amount of on-chip resources needs to stay dark, i.e., power-gated, in order to avoid thermal emergencies. This phenomenon is known in the literature as dark silicon. Conventional resource management techniques allocate the cores of the chip to the ...
