PICMG releases COM-HPC specification

It defines five module sizes to deliver edge server performance for small, rugged data centres and embedded use.

The base specification will be accompanied later this year by a platform management interface specification, COM-HPC EEEP, and a carrier board design guide.


COM-HP-Carrier-Module“Twenty-six companies worked together over five years”, said COM-HPC working group chairman Christian Eder. “I owe a big thank you to the team for the dedication and excellence they all brought to the effort.”



COM-HPC does not replace COM Express.

There will be two classes of COM-HPC modules.

  • COM-HPC Client Module Type for  high-end embedded client products that need one or more displays
    Typical uses are foreseen in medical equipment, high-end instrumentation, industrial equipment, casino gaming equipment, ruggedised field PCs, transportation and defence systems.
  • COM-HPC Server Type for high-end headless (no display) embedded servers with lots of CPU capability, memory and I/O bandwidth – the latter including multiple 10 or 25Gbit/s Ethernet, and up to 65 PCIe lanes at up to Gen 5 speed.
    Typical uses are foreseen in embedded servers ruggedised for field use, autonomous vehicles, outdoor cellular base stations, geophysical field equipment, medical equipment and defence systems.

COM-HP from PICMGBoth client and server modules have a dedicated platform management interface – the first for a COM standard to include remote administration.

“The new open standard will enable multiple AI and Industry 4.0 applications, amongst others, to be realised by bringing server-level computing to the edge,” said PICMG president Jessica Isquith. “Adopting the specification provides a necessary standard to reduce time to market and stabilize costs for hundreds of solutions providers.”
