Intel’s Hyper-Threading Technology brings the concept of simultaneous multi-threading to the Intel Architecture. Hyper-Threading Technology makes a single physical processor appear as two logical processors; the physical execution resources are shared and the architecture state is duplicated for the two logical processors. From a software or architecture perspective, this means operating systems and user programs can schedule processes or threads to logical processors as they would on multiple physical processors. From a micro architecture perspective, this means that instructions from both logical processors will persist and execute simultaneously on shared execution resources.Intel's Hyper-Threading Technology brings the concept of simultaneous multi-threading to the Intel Architecture. This is a significant new technology direction for Intel's future processors. It will become increasingly important going forward as it adds a new technique for obtaining additional performance for lower transistor and power costs.
