Introduction The OPB PCI Arbiter provides arbitration among several PCI Master devices. Parametric selection determines the number of masters competing for PCI bus control. Both fixed and rotating arbitration schemes may be selected by programing a control register. Bus parking occurs in the case that no master requests PCI control. The particular master designated for parking is selected either with a pro- gramed register or by parametric selection. Register pro- gramming is accomplished through a slave interface to the OPB using the OPB_IPIF. An alternate use mode provides a PCI arbiter without an OPB interface. Achieved through appropriate parameter settings, this mode completely removes the program regis- ters and the OPB_IPIF leaving open the outputs to the OPB and connecting inputs from the OPB to logic zero. Without an OPB interface the PCI arbiter operates with rotating arbi- tration, the park master is set directly by parametric selec- tion and there is no facility to modify priorities or arbitration scheme. The arbiter will start with master zero as highest priority then follow the rotating arbitration scheme to deter- mine successive priorities. The OPB_PCI_Arbiter follows arbitration guidelines defined in the PCI Local Bus Specification. Functional operation is verified to 75 MHz to ensure operation for 66 MHz PCI sys- tems.
