Abstract
An apparatus and method are described for the efficient migration of architectural state between processor cores. For example, a processor according to one embodiment comprises: a first processing core having a first instruction execution pipeline including first register set for storing a first architectural state of a first thread being executed thereon; a second processing core having a second instruction execution pipeline including a second register set for storing a second architectural state of a second thread being executed thereon; and architectural state migration logic to perform a direct, simultaneous swap of the first architectural state from the first register set with the second architectural state from the second register set responsive to detecting that the execution of the first thread is to be migrated from the first core to the second core.
