Earlier this year, PICMG® announced the release of the new COM-HPC specification. COM-HPC (for “Computer on Module – High Performance Computing”) is an open standard for high performance computer modules targeting the embedded applications
The development of COM-HPC exceeds the demand for high-speed performance in embedded computers. COM-HPC coexists with the COM Express® specification, but provides the scalability and enhanced performance for next-gen embedded system design.
COM-HPC supports two different module types. COM-HPC server modules are targeted for edge server applications. COM-HPC client modules support robust embedded computing. COM-HPC provides access to more system memory (up to 1 TB RAM) and system flexibility for various compute engines like GPGPUs, FPGAs and DSPs.
COM-HPC Interconnect Solutions
COM-HPC provides system and interface flexibility by adopting a pair of 400 pin connectors (800 pins total). Samtec COM-HPC Interconnect Solutions support protocols such as PCIe® 5.0 (32 GT/s) and up to 100 Gb Ethernet in 5 mm and 10 mm stack heights.
COM-HPC connectors feature an open-pin-field array, which maximizes grounding and routing flexibility by allowing system architects to route high-performance differential-pairs, single-ended referential signals, and power, via the same interconnect.
With a small 0.635 mm pitch, the COM-HPC connectors feature an ultra-micro footprint. COM-HPC connectors use a 2.2 / 2.4 / 2.2 mm row pitch. The spacing allows PCB designers more room to route differential signals. Crosstalk is improved with the increased space and the ability to add more ground vias around the differential signals.
Upcoming Samtec/Mouser COM-HPC Webinar
The initial COM-HPC specification is now completely released. New solutions from PICMG COM-HPC members are available. New COM-HPC designs are starting as we speak. Addition standards work is on-going.
For the latest details in all things COM-HPC, Samtec and Mouser Electronics are sponsoring a webinar PICMG COM-HPC® – New Open Standard for High Performance Compute Modules. Technical experts from Samtec will provide an overview of the COM-HPC specification and eco-system. Addition details around the latest COM-HPC standards efforts will also be presented.
