Abstract
Apparatuses, methods, systems, and chip-containing products are disclosed, which relate to an arrangement comprising a level N cache level and a level M cache level, where M is greater than N. The level N cache level comprises a plurality of linefill slots and performs a slot allocation procedure in response to a lookup miss in dependence on a linefill slot occupancy criterion. The slot allocation procedure comprises allocation of an available slot of the plurality of slots to a pending linefill request generated in response to the lookup miss. The level N cache level effects a modification of the slot allocation procedure in dependence on the linefill slot occupancy criterion and is responsive to the linefill slot occupancy criterion being fulfilled to cause a linefill delegation action to be instructed to the level M cache level.
