  • Mechanism for storing system level attributes in a translation lookaside buffer
    Patent number: 6304944
    Abstract: A method and apparatus for improving the efficiency of the cacheability (and other attribute) determination by making the information from the region register available during linear to physical address translation, rather than serially upon completion of the address translation. Address range comparisons are made when the TLB is loaded. That is, attribute information stored in a region register or registers is compared with physical addresses corresponding to translations loaded in a translation lookaside buffer reload operation. The present invention thus advantageously removes the region register compare operation from the path to memory.
    Type: Grant
