What is VITA 74 A.K.A. VNX?

As computers continue to proliferate in the avionic and military market, size, weight and power, also known as SWaP, are key issues when defining new products and projects. System integrators, project managers and engineers are challenged on which optimal direction to choose to address these new requirements. With the advancement of chip technology, more can be done with less. System-on-a-Chip (SoC) or Everything-on-a-Chip (EoC) make it easier to add more abilities such as video, Ethernet or I/O support on a single chip rather than on separate boards thus saving size and weight. But the biggest challenge has been what form factor should be chosen? PC 104? mTCA? Proprietary? A second important issue is the preference by the military and avionic sectors for standards such as VITA and ANSI. Standards provide better interoperability and drives down costs by allowing more suppliers to meet the demand with commercially-off-the-shelf (COTS) products.
