Abstract:
An apparatus, method, machine-readable medium, and system are disclosed. In one embodiment the apparatus is a micro-page table engine that includes logic that is capable of receiving a memory page request for a page in global memory address space. The apparatus also includes a translation lookaside buffer (TLB) that is capable of storing one or more memory page address translations. Additionally, the apparatus also has a page miss handler capable of performing a micro physical address lookup in a page miss handler tag table in response to the TLB not storing the memory page address translation for the page of memory referenced by the memory page request. The apparatus also includes memory management logic that is capable of managing the page miss handler tag table entries. The micro-page table engine allows the TLB to be an agent that determines whether data in a two-level memory hierarchy is in a hot region of memory or in a cold region of memory. When data is in the cold region of memory, the micro-page table engine fetches the data to the hot memory and a hot memory block is then pushed out to the cold memory area.
