Abstract
A translation buffer is described which can translate virtual addresses to physical addresses wherein the virtual addresses have varying page sizes. The translation buffer includes a decoder to generate a hashed index, the index identifying an entry into two arrays. The first of the two arrays identifies a corresponding physical page address and the other array identifies a corresponding variable page address that in comparison to a variable portion of the virtual address, will indicate whether the entry in the first array has a matching entry. If the first array identifies a matching physical page address, then the physical page address is combined with the offset of the virtual address to yield a physical address translation of the virtual address.
