Abstract: The present invention comprises a multiple functional block integrated circuit device for connecting to an external peripheral component interconnect (PCI) bus. The present invention includes an integrated circuit adapted to be coupled to an external PCI bus. The integrated circuit includes a plurality of functional blocks. Each of the plurality of functional blocks performs a function and comprises either a master functional block or a target functional block. A target bus adapted to transmit data signals is integral with the integrated circuit. The target bus is coupled to each of the plurality of functional blocks. A master bus adapted to transmit data signals is also integral with the integrated circuit. The master bus is coupled to each master functional block. A target bus interface integral with the integrated circuit is coupled to the target bus.

Abstract: A multiple peripheral component interconnect (PCI) agent integrated circuit device for connecting to an external PCI bus. In one embodiment, the present multiple PCI agent integrated circuit device includes, an integrated circuit which is adapted to be coupled to an external PCI bus. The integrated circuit includes an internal PCI bus built in. The internal PCI bus is adapted to transmit data signals thereon, and is further adapted to couple to the external PCI bus via a connector. A plurality of PCI agents are built into the integrated circuit, wherein each of the plurality of PCI agents are capable of performing an independent function. Each of the plurality of PCI agents are coupled to the internal PCI bus. A predictive arbiter is built into the integrated circuit and is coupled to both the internal PCI bus and to the plurality of PCI agents. The predictive arbiter arbitrates between the PCI agents for ownership of the internal PCI bus.
