Abstract:
An apparatus comprising:a first translation lookaside buffer for fixed size pages; a second translation lookaside buffer for variable size pages; and an OR device, an input of the OR device connected to the second translation lookaside buffer, wherein the OR device is provided for translating a linear address to a physical address using a fixed size translation lookaside buffer entry stored in the second translation lookaside buffer; wherein the fixed size translation lookaside buffer entry comprises an n-bit physical page frame number; and wherein the OR device provides an OR function of a first input, which is a lower k bits of the n-bit physical page frame number, and a second input, which is an upper k bits of an offset of the linear address, and the OR device outputs k bits forming a portion of the physical address for a translation of the linear address to the physical address.
