Abstract
The present invention provides an apparatus and a method for variable size pages using fixed size TLB (Translation Lookaside Buffer) entries. In one embodiment, an apparatus for variable size pages using fixed size TLB entries includes a first TLB for fixed size pages and a second TLB for variable size pages. In particular, the second TLB stores fixed size TLB entries for variable size pages. Further, in one embodiment, an input of an OR device is connected to the second TLB to provide a cost-effective and efficient implementation for translating linear addresses to physical addresses using fixed size TLB entries stored in the second TLB.
