ESCRIPTION
The PMC-605 PCI-P0 Bridge Module is a single-width PMC module that extends the local PCI
bus of its host Single Board Computer (SBC) out to the SBC’s P0 connector. This enables the
SBC to communicate with other similarly equipped cards in the VMEbus system over a high-
speed PCI bus (referred to as the PCI-P0 bus in this manual).
The PMC-605 performs such functions as:
• Expanding the number of PMC modules attached to a processor card (single board
computer or digital signal processor)
• Interconnecting multiple processor cards via a high-speed PCI secondary backplane.
• Providing a private PCI data path to custom I/O cards.
Figure 1.1 shows a sample application of the PMC-605. The two SBCs use the PMC-605 to
access each others’ shared PCI resources while the SVME/DMV-210 Carrier Card extends the
PCI bus of each single board computer with additional I/O capabilities.
