Abstract
A data processing apparatus and a method of processing data are disclosed, in which address translations between first addresses used in a first addressing system and second addresses used in a second addressing system are locally stored. Each stored address translation is stored with a corresponding identifier. In response to an invalidation command to perform an invalidation process on a selected stored address translation the selected stored address translation is invalidated, wherein the selected stored address translation is identified in the invalidation command by a specified first address and a specified identifier. The invalidation process is further configured by identifier grouping information which associates more than one identifier together as a group of identifiers, and the invalidation process is applied to all stored address translations which match the specified first address and which match any identifier in the group of identifiers to which the specified identifier belongs.
