International Classification:

G06F 9/46

US Classification:

718103

Abstract:

A method and apparatus for providing quality of service in a multi-processing element environment based on priority is herein described. Consumption of resources, such as a reservation station and a pipeline, are biased towards a higher priority processing element. In a reservation station, mask elements are set to provide access for higher priority processing elements to more reservation entries. In a pipeline, bias logic provides a ratio of preference for selection of a high priority processing

Abstract:

Systems, methods, and apparatuses relating to circuitry to implement toggle point insertion for a clustered decode pipeline are described. In one example, a hardware processor core includes a first decode cluster comprising a plurality of decoder circuits, a second decode cluster comprising a plurality of decoder circuits, and a toggle point control circuit to toggle between sending instructions requested for decoding between the first decode cluster and the second decode cluster, wherein the toggle point control circuit is to: determine a location in an instruction stream as a candidate toggle point to switch the sending of the instructions requested for decoding between the first decode cluster and the second decode cluster, track a number of times a characteristic of multiple previous decodes of the instruction stream is present for the location, and cause insertion of a toggle point at the location, based on the number of times, to switch the sending of the instructions requested for decoding between the first decode cluster and the second decode cluster.
