CompactPCI (Technical)

This section does not currently contain so much in depth information as I would like.

Since CompactPCI is based on PCI you should first refer to the PCI standard. This only explains the extensions CompactPCI specifies.

Overview:

A CompactPCI system is composed of up to eight CompactPCI card locations:

One System Slot
Up to seven Peripheral Slots

The connector has 7 columns with 47 rows. They are divided into groups:

Row 1-25: 32-bit PCI
Row 26-47: Additional pins for 64-bit PCI (System Slot boards must use it).
Row 26-28 and 40-42: Primarily implemented on System Slot boards.

The following signals must be terminated:

AD0-31
C/BE0#-C/BE3#
PAR
FRAME#
IRDY#
TRDY#
STOP#
LOCK#
IDSEL
DEVSEL#
PERR#
SERR#
RST#

The following signals must be terminated if used:

INTA#
INTB#
INTC#
INTD#
SB0#
SDOBE
AD32-AD63
C/BE4#-C/BE7#
REQ64#
ACK64#
PAR64#

The following signals do no require a stub termination:

CLK
REQ#
GNT#
TDI#
TDO
TCK
TMS
TRST#

The System Slot board must pullup the following signals (even if not used):

REQ64#
ACK64#
