1 COM-HPC Introduction
COM-HPC®(for “Computer on Module – High Performance Computing”) is a PICMG®sponsored open standard for a family of high
performance computer modules targeting the embedded computer space. The embedded space differs from the commercial space
with respect to features such as long-term availability, extended temperature operation, mechanical ruggedness, hardware and
firmware that can be customized to the application, and Module vendor support to product developers. In the COM development
model, the COMs are standard product offerings, and they are used with Carrier boards that are usually application specific, with
additional features, connectors and geometries suited to the customer product at hand.
The COM-HPC®modules are available in following form factors:
⚫Size A - 95 mm x 120 mm
⚫Size B - 120 mm x 120 mm
⚫Size C - 160 mm x 120 mm
⚫Size D - 160 mm x 160 mm
⚫Size E - 200 mm x 160 mm
