Abstract

A method and apparatus for matching parent processor address translations to media processors' address translations and providing concurrent memory access to a plurality of media processors through separate translation table information. In particular, a page directory for a given media application is copied to a media processor's page directory when the media application allocates memory that is to be shared by a media application running on the parent processor and media processors.
