Abstract:
A processor includes a translation lookaside buffer (TLB) including a data array and a compare unit. The data array includes a number of entries each configured to store a respective translated physical address. In response to a read access to a given entry of the TLB, the data array is configured to output within a particular clock cycle, the respective translated physical address stored in the given entry. In addition the compare unit may be configured to compare the respective translated physical address output by the data array with a number of additional addresses. The compare unit may also be configured to provide a hit indication for each of the additional addresses within the particular clock cycle.
