An Evolution in the COM Express Specification

Version 1

    Revision 2.0 of the COM Express specification is an evolutionary initiative to refresh the COM Express specification in support of new technologies and interfaces as well as deal with legacy interface obsolescence issues. The original module types in the COM Express Revision 1.0 specification anticipated this transition and set the stage for this evolution from legacy parallel interfaces to differential serial interfaces.


    In this whitepaper, Bob Pebly – RadiSys CTO Fellow, follows up on his popular whitepaper on the original COM Express Specification (COM Express: The Next Generation Computer on Module Standard, June, 2005) and discusses the success and evolution of COM Express in light of recently adopted COM Express Revision 2.0 specification.
