Emerson MVME5100 Series VME Bus Processor Module

Product core positioning

MVME5100 is a high-performance embedded VME bus processor module launched by Emerson Network Power. Based on the PowerPlus II architecture, it is positioned as a highly reliable computing solution for "business critical" fields such as defense aerospace, industrial automation, and medical equipment. It combines the rich I/O functions of traditional single board computers with the flexibility of dual PMC expansion slots, supports multi operating system and complex peripheral adaptation, and can achieve supercomputing level performance (such as 582MB/s memory read bandwidth and 640MB/s burst write bandwidth) in a single VME slot, meeting the requirements of embedded application scenarios with strict requirements for computing power, stability, and scalability.
