类型：软IP 简短描述：OPB PCI Arbiter 详细描述：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 programed register or by parametric selection. Register programming is accomplished through a slave interface to the OPB using the OPB_IPIF. 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 systems. 工艺：0.25um 代工厂： 应用： 特色：
