Abstract
A design structure embodied in a machine readable storage medium for at least one of designing, manufacturing, and testing a design is provided. The design structure includes a page table walker. The page table walker is moved from its conventional location in the memory management unit associated with the data processor to a location in main memory i.e. the main memory controller. As a result, wherein the processing of requests for data could selectively avoid or bypass cumbersome caches associated with the data processor.
Claims18
A design structure embodied in a machine readable storage medium for at least one of designing, manufacturing, and testing a design, the design structure comprising:
- a computer system comprising:
- a data processor unit connected to a main memory, said data processor unit including a memory management unit for controlling the conversion of an address of requested data received from a processor into a physical address of said requested data,
- said main memory including:
- an apparatus for storing the data being accessed in pages at said physical addresses;
- a page table accessed by said memory management unit for converting to said page addresses;
- and
- a page table walker for proceeding through the entries on said page table.
A design structure embodied in a machine readable storage medium for at least one of designing, manufacturing, and testing a design, the design structure comprising:
- a main memory unit adapted for operative association with a data processor, said main memory unit, comprising:
- an apparatus for storing the data being accessed in pages at said physical addresses;
- a page table accessed by said memory management unit for converting to said page addresses;
- and
- a page table walker for proceeding through the entries in said page table.
