摘要：With a shared common memory, internal requests of a multimedia processor (70) is processed to generate a request (140) optimized in format. Each internal request is selected by the request controller according to a system priority. Each of external requests is independently subjected to an analyzing process for each format adapter (160), and is converted into a format compatible with a predetermined internal format of the multimedia processor. Thus, one or more external processors share a common memory to enable the external processors to access a bulk memory storage of a multimedia processor.
