    Abstract: In an embodiment, a processor includes a cache data array including a plurality of physical ways, each physical way to store a baseline way and a victim way; a cache tag array including a plurality of tag groups, each tag group associated with a particular physical way and including a first tag associated with the baseline way stored in the particular physical way, and a second tag associated with the victim way stored in the particular physical way; and cache control logic to: select a first baseline way based on a replacement policy, select a first victim way based on an available capacity of a first physical way including the first victim way, and move a first data element from the first baseline way to the first victim way. Other embodiments are described and claimed.
