Abstract
A method and apparatus for allowing multiple devices access to an address translation cache while cache maintenance operations are occurring at the same time. By interleaving the commands requiring address translation with maintenance operations that may normally take many cycles, address translation requests may have faster access to the address translation cache than if maintenance operations were allowed to stall commands requiring address translations until the maintenance operation was completed.
