6U cards have an identical J1, a J2 that is always used for 64-bit PCI, as well as J3, J4, and J5 connectors for a variety of uses either as user-defined I/O or specified signaling such as Telephony and/or Ethernet signaling. Hot-plugging is a supported feature of CompactPCI.
This makes 64-bit bus communication impossible. The new J2 connector type itself is 100% compatible with the legacy one. The J1 bus connector conforms with the CompactPCI definition. In all, CompactPCI PlusIO is 100% compatible with legacy 32-bit CompactPCI in 3U and 6U format (single and double Eurocards).
Many mezzanine connector styles are commercially available for this purpose, however PMC mezzanine applications usually use the 1.0 mm pitch 64 pin connector described in IEEE 1386. [2] A PMC can have up to four 64-pin bus connectors. The first two ("P1" and "P2") are used for 32 bit PCI signals, a third ("P3") is needed for 64 bit PCI signals.
The original standard was a 16-bit bus, designed to fit within the existing Eurocard DIN connectors. However, there have been several updates to the system to allow wider bus widths. The current VME64 includes a full 64-bit bus in 6U-sized cards and 32-bit in 3U cards. The VME64 protocol has a typical performance of 40 MB/s. [3]
The OpenVPX System Specification describes technical implementation details for 3U and 6U VPX payload and switch modules, backplane topologies, and chassis products, which provides guidance on how to build interoperable computing and communication systems. OpenVPX was a development of, and complementary to, VPX.
The Europe Card Bus (ECB or ECB-bus [1]) is a computer bus developed in 1977 by the company Kontron, mainly for the 8-bit Zilog Z80, Intel 8080 and Intel 8085 microprocessor families. Physical format [ edit ]

The video core in the SiS 630/730 is based on the 128-bit SiS 305. The VGA core is capable of using either its own dedicated local memory (giving a 128-bit memory interface) or taking a chunk out of system memory (usually configurable from between 8 MB to 64 MB, giving 64-bit memory interface).
