摘要： 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.

摘要： The present invention discloses a system and method for communicating real-time, multimedia data between a host CPU and an external multimedia device using a pair of first-in-first-out (FIFO) buffers. Data from the CPU is stored in a first FIFO buffer and subsequently retrieved by the multimedia device. Data from the multimedia device is stored in a second FIFO buffer and subsequently retrieved by the CPU for processing. The FIFO buffers provide indications to the CPU for the CPU to store more data in the first FIFO buffer and for the CPU to retrieve data from the second FIFO buffer.

摘要： A computer system and method optimized for real-time multimedia applications are presented. The computer system, including a dedicated multimedia engine directly to a real-time data cache, provides increased performance over current computer architectures. The multimedia engine includes at least one DSP engine which coupled through at least one I/O channel to I/O ports. Obtaining multimedia commands and data from main memory and/or the real-time data cache, the multimedia engine performs a number of multimedia operations including audio and video functions. A CPU, coupled through a chip set logic or bridge logic to the main memory, generates multimedia commands and data. The CPU groups multimedia commands and data into separate command and data elements, and writes the command and data elements to a multimedia address space in main memory. The CPU also writes element structure information to the multimedia address space. The element structure information includes location information used to retrieve multimedia commands and data from main memory. The real-time data cache allows multimedia data from an external source to be stored in a location other than main memory, and allows this multimedia data to be shared by the CPU and the multimedia engine. The real-time data cache may also store multimedia commands and data for use by the multimedia engine.
