Modular real-time target machine - CompactPCI Concept

CompactPCI is based on a card cage and passive bus backplane in the Eurocard form factor. CompactPCI is available in a 3U and 6U height version. The 6U version is seen as the 'modern' VME system replacement, while the 3U version brings the 'VME system concept' to the world of typical sized PCI bus based x86 computers.

Speedgoat's Modular real-time target machine is based on the 3U CompactPCI (cPCI) version (standard).

The card cage is part of the chassis/enclosure and is located towards the front of the chassis. The cards (modules) are inserted from the front of the chassis. And because the cards' specific connectors are mounted on the cards' face plate all peripheral and I/O signals are accessible at the front of the system.

Furthermore, power supplies are available in the Eurocard form factor as well and therefore are inserted like cPCI cards from the front despite the fact that they use a dedicated power bus backplane. Speedgoat has chosen this approach for its Modular real-time target machine.

This means that all active components are accessible from the front. Only the power supply input line connector (AC or DC) is found at the back of the chassis.

The cPCI standard also defines so called rear-I/O where signals leave at the back of the chassis. Speedgoat's Modular real-time target machine doesn't incorporate the concept of rear-I/O but the Modular machine's chassis depth has been selected in such a way that it can support rear-I/O for custom-built Modular machines.

The space behind the card cage is used for backplane inter-cabling and for the fans along the full width of the chassis to provide properly distributed air flow for the cooling of the entire system.

The 3U CompactPCI bus backplane carries bus signals electrically compatible with the PCI bus standard. Each bus backplane section contains an active PCI bridge to cover the PCI bus load. The cPCI bus connectors are shielded, have very good EMI protection, and are optimized for arbitrary placement of cards (I/O modules) without leading to bus termination problems.

The cPCI bus backplanes of Speedgoat's Modular machine makes use of the 32bit/33MHz PCI bus standard. The backplane (backplane sections) offers a system slot for the CPU module and up to 13 I/O modules.
