Abstract
Two translation lookaside buffers may be provided for simpler operation in some embodiments. A hardware managed lookaside buffer may handle traditional operations. A software managed lookaside buffer may be particularly involved in locking particular translations. As a result, the software's job is made simpler since it has a relatively simpler, software managed translation lookaside buffer to manage for locking translations.
Claims23
A method comprising:
- providing two translation lookaside buffers for one microprocessor.
An article storing instructions that, if executed, enable a processor-based system to:
- search in a software managed translation lookaside buffer for a translation from a linear to a physical address and, if the translation is not resident in said software managed translation lookaside buffer, look for said translation in a hardware managed translation lookaside buffer.
A system comprising:
- a processor comprising a pair of translation lookaside buffers, only one of said buffers having page table walk logic;
- and
- a wireless interface coupled to said processor.
Dependencies are inferred from the claim text.
