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.

For a copy of the full CompactPCI standard, contact:

Overview:

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

  • One System Slot
  • Up to seven Peipherial Slots

The connector has 7 columns with 47 rows. They're 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#

Есть ли справедливость в жизни?
Конечно есть, уверен!
Вроде как должна быть, но...
Затрудняюсь ответить...
