5.1
Features
Tundra’s Universe IIB (CA91C142) interfaces the local 32-bit PCI bus to the VMEbus. The following lists
some of the Universe IIB’s features on the USPIIi-1v board:
• 33 MHz, 32-bit PCI bus interface
• Fully compliant, high performance 64-bit VMEbus interface
• Integral FIFOs buffer with multiple transactions from the PCI bus to the VMEbus and from the
VMEbus to the PCI (both directions)
• Programmable DMA controller with linked list support
• A broad range of VMEbus address and data transfer modes:
– A32/A24/A16 master and slave transfer, except for A64 and A40
– D64/D32/D16/D08 master and slave transfer, except for MD32
– MBLT, BLT, ADOH, RMW, LOCK, and location monitors
• Support for full VMEbus System Controller
• Nine user programmable slave images on the VMEbus and the PCI bus ports
• Seven interrupt lines
• Auto initialization for the slave only applications
• Programmable registers from both the VMEbus and the PCI bus
• Support for four mailbox registers
• Support for four location monitors
• Support for eight semaphores
• Support for RMW cycles and lock cycles
This chapter is intended to outline the VMEbus to PCI Bus interface on the USPIIi-1v. If more detailed
information is need, please refer to the Tundra “Universe II User’s Manual”, Spring 1998.
Note —
All registers on the Universe IIB are little-endian.
