Heterogeneous Multi-core Architectures

Transistor count continues to increase for silicon devices following Moore's Law. But the failure of Dennard scaling has brought the computing community to a crossroad where power has become the major limiting factor. Thus future chips can have many cores; but only a fraction of them can be switched on at any point in time. This dark silicon era, where significant fraction of the chip real estate remains dark, has necessitated a fundamental rethinking in architectural designs. In this context,

Heterogeneous multi-cores can potentially provide energy-efficient computation as only the cores most suitable for the current computation need to be switched on. This article presents an overview of the state-of-the-art in heterogeneous multi-core landscape.
