Abstract

A system includes a processing core built on a semiconductor substrate, the processing core having a first sub core and a second sub core, each of the first and second sub cores configured to perform a processing function, and a plurality of power rails traversing a dimension of the processing core and spanning from the first sub core to the second sub core, each of the power rails being configured to provide an operating voltage to the first and second sub cores, and wherein a boundary between the first sub core and the second sub core is irregularly shaped, and wherein each of the first and second sub cores corresponds to a respective power domain.
