Abstract:
A method and apparatus for sharing translation buffer entries between multiple processing resources is herein described. A sharing field in a translation entry is to represent that the translation entry is to be associated with/shared between a plurality of processing resources, if the translation entry is determined to be the same for the plurality of processing resources. Upon a miss to a translation buffer associated with a first resource, a new translation for the first resource is completed. The new translation is compared to other entries in the translation buffer to determine if any other entries include the same translation for other resources. In response to determining other resources are associated with the same translation, a sharing field in a translation entry is to indicate which resources the entry is to be associated with/shared between.
