Compactpci Interface - Kontron CP6500-V User Manual

Functional Description
2.2.19

CompactPCI Interface

The CP6500-V supports a flexibly configurable, hot swap CompactPCI interface. In the System
Master slot the interface is in the transparent mode, and in the peripheral slot the CompactPCI
interface is isolated so that it cannot communicate with the CompactPCI bus. This mode is
known as "passive mode".
2.2.19.1 System Master Configuration
In a system slot, the CP6500-V can communicate with all other CompactPCI boards through a
32-bit/3MHz interface.
The CP6500-V supports up to seven CompactPCI loads through a passive backplane.
The CP6500-V is fully compliant with the PCI Local Bus Specification Rev. 2.2 for 32-bit/
33 MHz.
2.2.19.2 PCI-to-PCI Bridge
The Texas Instruments® PCI2050BI bridge is a 32-bit 33 MHz PCI-to-PCI bridge device. It sup-
ports up to seven CompactPCI loads through a passive backplane.
The PCI2050I is a second generation PCI-to-PCI bridge and is fully compliant with the PCI Lo-
cal Bus Specification Rev. 2.2.
The PCI-to-PCI bridge allows the primary and secondary PCI bus to operate concurrently. A
master and target on the same PCI bus can communicate while the other PCI bus is busy.
2.2.19.3 Peripheral Master Configuration (Passive Mode)
In a peripheral slot, the board receives power but does not communicate on the CompactPCI
bus; all CompactPCI signals are isolated.
In this configuration, the communication is achieved via the two Fast Ethernet ports as defined
in the PICMG 2.16 specification. In the passive mode, the board may be hot-swapped.
2.2.19.4 Packet Switching Backplane (PICMG 2.16)
The CP6500-V supports a dual Fast Ethernet link port (Node) on the J6 connector in accor-
dance with the CompactPCI Packet Switching Backplane Specification PICMG 2.16, Version
1.0. The two nodes are connected in the chassis via the CompactPCI Packet Switching back-
plane to the Fabric slots "A" and "B".
The PICMG 2.16 feature can be used in the system slot and in the peripheral slot.
2.2.19.5 Hot Swap Support
To ensure that a board may be removed and replaced in a working bus without disturbing the
system, the following additional features are required:
• Power ramping
• Precharge
• Hot swap control and status register bits
• Automatic interrupt generation whenever a board is about to be removed or replaced
• An LED to indicate that the board may be safely removed
