Abstract: A computer system optimized for real-time applications which provides increased performance for real-time applications over current computer architectures. The system includes a dedicated multimedia engine coupled directly to the main memory which performs real-time operations, including audio and video functions, as well as others. The multimedia engine includes multimedia memory and one or more DSP engines. The DSP engines may comprise either dedicated audio or video engines or general purpose DSP engines. The DSP engines couple through one or more I/O channels to respective video, audio and communication ports. The multimedia engine includes video ports for coupling to a video monitor, audio ports for coupling to speakers and one or more communication ports. The multimedia memory in the multimedia engine comprises a portion of the main memory address space. Thus the multimedia is used for real-time or multimedia data and is also used by the CPU as overflow memory space.
