A design structure embodied in a machine readable storage medium for designing, manufacturing, and/or testing a design for accessing a processor cache is provided. The design structure comprises a processor having a processor core, a level one cache, and circuitry. The circuitry is configured to execute an access instruction in the processor's core, wherein the access instruction provides an untranslated effective address of data to be accessed by the access instruction, determine whether the processor core's level one cache includes the data corresponding to the effective address of the access instruction, wherein the effective address of the access instruction is used without address translation to determine whether the processor core's level one cache includes the data corresponding to the effective address, and provide the data for the access instruction from the level one cache if the level one cache includes the data corresponding to the effective address.
