Applying OpenVPX to Single Board Computers

For more than two decades, single board computers (SBCs) built on open standards have been largely based on specifications from two preeminent industry organizations, VITA and PICMG. For the 6U Eurocard format, each organization has developed a platform that has provided the basis for standardized SBCs; where VITA introduced the VMEbus standard and derivatives, PICMG introduced CompactPCI bus and its derivatives. Both bus structures use a parallel bus architecture, which has its performance limitations, hence the recent movement to use fabric-based technologies.
