摘要： A trace management architecture to enable the reuse of uops within one or more repeated traces. More particularly, embodiments of the invention relate to a technique to prevent multiple accesses to various functional units within a trace management architecture by reusing traces or sequences of traces that are repeated during a period of operation of the microprocessor, avoiding performance gaps due to multiple trace cache accesses and increasing the rate at which uops can be executed within a processor.

摘要： Some implementations provide techniques and arrangements to migrate threads from a first core of a processor to a second core of the processor. For example, some implementations may identify one or more threads scheduled for execution at a processor. The processor may include a plurality of cores, including a first core having a first characteristic and a second core have a second characteristic that is different than the first characteristic. Execution of the one or more threads by the first core may be initiated. A determination may be made whether to apply a migration policy. In response to determining to apply the migration policy, migration of the one or more threads from the first core to the second core may be initiated.

摘要： For one disclosed embodiment, a processor comprises a first processor core, a second processor core, and a cache memory. The first processor core is to save a state of the first processor core and to enter a mode in which the first processor core is powered off. The second processor core is to save a state of the second processor core and to enter a mode in which the second processor core is powered off. The cache memory is to be powered when the first processor core is powered off. The first processor core is to restore the saved state of the first processor core in response to the first processor core transitioning to a mode in which the first processor core is powered. The second processor core is to restore the saved state of the second processor core in response to the second processor core transitioning to a mode in which the second processor core is powered. Other embodiments are also disclosed.

摘要： With the progress toward multi-core processors, each core is can not readily ascertain the status of the other dies with respect to an idle or active status. A proposal for utilizing an interface to transmit core status among multiple cores in a multi-die microprocessor is discussed. Consequently, this facilitates thermal management by allowing an optimal setting for setting performance and frequency based on utilizing each core status.
