New PICMG standard is ratified

September 7, 2017 Rich Nass

The newest PICMG standard cPCI Serial Space, CPCI-S.1 R1.0, was now officially ratified, thanks to some hard work by members of the PICMG working group. The goal of the new technical PICMG sub-committee “CompactPCI Serial Space” (cPCI Serial Space) was to extend the current CompactPCI Serial specification by a sub-standard covering the specific requirements for space applications.

The new spec can be viewed as an extension of the existing CompactPCI Serial standard. The two key changes in the extension of the CompactPCI Serial specification are the definition of a dual star architecture for increased availability, and allowing the integration of different communication protocols common in space applications for both.

The result is a parallel and flexible use of the full-mesh Ethernet network via the backplane, as well as the dual-star architecture via PCI-Express or any other protocol like SpaceWire, TTEthernet, EtherSpace and so on, for both the CPU card and all peripheral cards. Note that previusly, such a topology was restricyed to Ethernet.
