VPX: The Rugged Bus Architecture for Embedded Military Applications

For over two decades, the VMEbus has maintained its position as the open standard bus architecture of choice for defense and aerospace applications. While VME, a parallel bus, promises to continue its reign as the most popular embedded board standard for years to come, it has become clear over the last several years that, for an emerging class of very demanding highend applications such as radar and signal processing, a new higher-bandwidth bus architecture is required.
