The present invention provides a digital signal processor (DSP) to peripheral component interconnect (PCI) bus interface/bridging system. The system includes an intermediate bus; a bridge module that is coupled between the PCI bus and the intermediate bus. The bridge module includes a PCI interface and an intermediate bus interface and an IDMA channel coupled between the PCI interface and the intermediate bus interface. A control module is coupled between the bridge module and the DSP circuit, said control module having an intermediate bus control circuit and a DSP control circuit having a slave port controller coupled to the slave port (HPI) of the DSP and a master port controller coupled to the master port (EMIF) of the DSP circuit, whereby the master port continues to transfer data from the DSP circuit to the PCI bus when an additional master circuit is asserted on the PCI bus. The system provides a direct connect solution that also provides arbitration for multiple DSPs.
