Abstract
A processor core processes a translation load instruction including a protection field specifying a desired access protection to be specified in a translation entry for a memory page. Processing the translation load instruction includes calculating an effective address within the memory page and ensuring that a translation entry containing the desired access protection is stored within at least one translation structure of the data processing system.
