PCI Bus 0 Local Bus Devices

The MV64360 PCI Bus 0 local bus contains the Tsi148 ASIC and PCI6520 PMCSpan bridge.

Tsi148 ASIC

The VMEbus interface is provided by the Tsi148 ASIC. Tempe is a PCI-X bus to VMEbus interface chip. While Tsi148 has many of the same features as the VMEchip2 and Universe, it includes new features and enhancements. Therefore, Tsi148 is not register compatible with the VMEchip2 or Universe chips. See the Tsi148 User’s Manual from Tundra Semiconductor listed in Appendix A, Related Documentation, for further details.

PCI6520 PMCSpan Bridge

The PMCSpan interface is provided by the PCI6520. PCI6520 is a PCI-X- to-PCI-X transparent bridge to interface between PMCspan bus and the local PCI0 bus. This part operates asynchronously between primary/local
