ABSTRACT:
A system, apparatus and method for handling switching among threads within a multithread processor are described herein. Embodiments of the present invention provide a method for multithread handling that includes fetching and issuing one or more instructions, corresponding to a first instruction execution thread, to an execution block for execution during a cycle count associated with the first instruction execution thread and when the instruction execution thread is in an active mode. The method further includes switching a second instruction execution thread to the active mode when the cycle count corresponding to the first instruction execution thread is complete, and fetching and issuing one or more instructions, corresponding to the second instruction execution thread, to the execution block for execution during a cycle count associated with the second instruction execution thread. The method additionally includes resetting the cycle counts when a master instruction execution thread is in the active mode. Other embodiments may be described and claimed.
