PROCESSOR WITH ADVANCED OPERATING SYSTEM SUPPORT

摘要

A computer processor may include a plurality of hardware threads. The computer processor may further include state processor logic for a state of a hardware thread. The state processor logic may include per thread logic that contains state that is replicated in each hardware thread of the plurality of hardware threads and common logic that is independent of each hardware thread of the plurality of hardware threads. The computer processor may further include single threaded mode logic to execute instructions in a single threaded mode from only one hardware thread of the plurality of hardware threads. The computer processor may further include second mode logic to execute instructions in a second mode from more than one hardware thread of the plurality of hardware threads simultaneously. The computer processor may further include witching mode logic to switch between the first mode and the second mode.
