What is the Difference Between VPX and VME?
VME (Versa Module Europa) is a legacy embedded computer standard with a parallel bus architecture. It was introduced in the 1980s and has since been used in many diverse applications. In the 2000s, developers designed VPX (VITA 46) to meet the higher performance demand from defense and aerospace applications. VPX uses high-speed serial components to deliver faster data transfer rates and bandwidth, whereas VME has higher latency due to its parallel bus system.
Newer systems typically implement VPX due to its high performance, however many legacy and industrial automation systems still utilize VME because of its reliability and longevity. Acromag provides both options. Our VME modules deliver long-term support and better compatibility with older technology, ideal for legacy defense systems and industrial automation. In contrast, our VPX modules with advanced performance and flexibility are great for demanding defense, aerospace, and scientific systems requiring cutting-edge computing power.
