Abstract: A device for and method of storing page table entries in a first cache. A first page table entry is received having a fragment field that contains address information for a requested first page and at least a second page logically adjacent to the first page. A second page table entry is generated from the first page table entry to be stored with the first page table entry. The second page table entry provides address information for the second page. The second page table entry has a configuration that is compatible with the first cache.

Abstract: A device and method for partitioning a cache that is expected to operate with at least two classes of clients (such as real-time clients and non-real-time clients). A first portion of the cache is dedicated to real-time clients such that non-real-time clients are prevented from utilizing said first portion.

Abstract: Systems, apparatuses, and methods for implementing a virtualized translation lookaside buffer (TLB) are disclosed herein. In one embodiment, a system includes at least an execution unit and a first TLB. The system supports the execution of a plurality of virtual machines in a virtualization environment. The system detects a translation request generated by a first virtual machine with a first virtual memory identifier (VMID). The translation request is conveyed from the execution unit to the first TLB. The first TLB performs a lookup of its cache using at least a portion of a first virtual address and the first VMID. If the lookup misses in the cache, the first TLB allocates an entry which is addressable by the first virtual address and the first VMID, and the first TLB sends the translation request with the first VMID to a second TLB.
