Abstract: A computer system is provided which includes a bus bridge coupled between a CPU local bus and a PCI bus. The bridge further includes a memory controller for controlling data transfers between a main memory and masters residing on either the CPU local bus or the PCI bus. A variety of peripheral devices are coupled to the PCI bus, including both real time resources and non-real time resources. For example, in one configuration, an SCSI controller, a network interface card, a video adapter, a video capture card, an audio adapter, and a telephony adapter are coupled to the PCI bus. A bus arbiter is advantageously provided for controlling and prioritizing ownership of the PCI bus based in part upon a real time indicator signal asserted by a bus agent that requires a real time data transfer. Each real time device is associated with a unique real time indicator signal. A relatively high level of arbitration priority is given to a master when it asserts its associated real time indicator signal at the time of a bus request. Bus agents which do not assert an associated real time indicator signal at the time of a bus request will lose the arbitration until all real time requests have been serviced. As a result, the system may support numerous real time processing resources while maintaining proper overall operation.

Abstract: 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.

Abstract: A programmable bus arbiter is provided that includes a plurality of arbitration priority registers each having a real time field for arbitration priority selection. Each real time bus master is associated with a designated real time field within the bus arbiter. Each real time field includes a real time access bit indicative of whether a real time access is to be initiated by the associated master and a priority code which sets the arbitration priority for the master with respect to other masters which may contend for the bus. Prior to initiating a real time data transfer, the real time field for a particular master may be programmed to indicate the real time transfer as well as to set the priority level for the request. A bus arbitration state machine detects the real time fields and grants bus mastership to real time bus agents in favor of other contending bus requests by non-real time agents.

Abstract: 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.
