Abstract
A method for performing predictive translation of a data address in a computer processing system includes organizing a translation lookaside buffer in a set associative manner having each set associated with multiple entries, wherein the multiple entries store consecutively ordered selections. Further, the method includes selecting a set of entries in the translation lookaside buffer in response to a base operand for the predictive translation. The method also includes comparing each entry in the selected set with an input address for determining whether or not the predictive translation failed. The method further includes the step of adding the base operand with an offset operand to produce the effective address. A system in accordance with the present invention includes effective address generation logic, including a base operand register to hold a base operand, and a translation lookaside buffer, translation lookaside buffer. The translation lookaside buffer includes a multiple number of entries organized in a set associative manner to map a desired number of consecutive pages into a single set, and coupled to the effective address generation logic to utilize selected bits of the base operand for selection of a set of entries and for comparing each entry in the selected set with an input address for determining whether or not the predictive translation failed.
