摘要： A computer system including separate digital and analog system chips which provides increased performance over current computer architectures. The computer system of the present invention includes a digital system chip which performs various digital functions, including multimedia functions and chipset functions, and a separate analog chip which performs analog functions, including digital to analog and analog to digital conversions. Thus the present invention optimizes silicon use and design by splitting up digital and analog functions on separate chips. The system of the present invention also separates digital noise from analog noise, allowing a higher degree of integration while increasing stability.

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 one or more DSP engines which 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. Multimedia memory is coupled to the local memory bus and stores data for the multimedia engine. 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： A computer system optimized for real-time applications which provides increased performance over current computer architectures. The system includes a standard local bus, such as the PCI bus, and also includes a dedicated real-time bus or multimedia bus. The PCI bus and the multimedia bus are comprised on the motherboard and include connector slots for receiving add-in cards. Multimedia device expansion cards each include two connectors which correspond to the PCI bus and the multimedia bus. Thus multimedia devices such as video cards, audio cards, etc., as well as communications devices, transfer real-time data through a separate bus without requiring arbitration for the PCI bus. The computer system of the present invention thus provides much greater performance for real-time applications than prior systems.

摘要： A computer system and method optimized for real-time multimedia applications are presented. The computer system, including a dedicated multimedia engine coupled directly to a real-time data cache, provides increased performance over current computer architectures. The multimedia engine includes at least one DSP engines which couple through at least one I/O channels 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.

摘要： A computer system and method for transferring multimedia commands and data to a dedicated multimedia engine and/or multimedia memory, wherein the multimedia engine 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 function, as well as others. The multimedia engine includes multimedia memory and one or more DSP engines. The CPU writes video and/or audio commands and data to the main memory. The CPU also preferably writes data structure information to the DMA engine which includes the main memory address where the commands and data reside. The DMA engine uses this information to retrieve the commands and data from main memory into the multimedia memory. The DMA engine preferably operates concurrently with the multimedia engine, thus allowing for improved performance. In an alternate embodiment, the CPU writes the main memory address space information to the multimedia engine, and the multimedia engine retrieves the commands and data from main memory into the multimedia memory prior to performing operations using the data.
