Developed in the 1980’s and popularized by VME Microsystems International Corporation (VMIC), the VME architecture was widely used in many programs with large I/O needs. It was built for the Motorola 68000 line of CPUs which was then replaced by the PowerPC architecture.
VME based systems had been the standard for real-time DAQ and embedded control systems for years. However, due to the age of most VME technology, as well as the lack of vendors in the market, many VME users are now facing “end-of-life” issues.
In today’s marketplace, VME is simply not seen as deserving significant investment in new product development or maintenance.
|Legacy VME are large, bulky, and often stationary systems. Modern DAQ and I/O systems have flexible sizing and VME just cannot compete.||The smaller the system, the less susceptible it is to shock/vibration. Modern DAQ and I/O drastically reduce weight so systems can be managed by one person.|
|Bulky VME systems have large power draws and heat issues. Modern systems are getting smaller and preserve or increase power capability. Boards are smaller and use less power and heat.||VME systems are either not compatible with or cannot be retrofitted with processors for modern workloads. A lack of processing capability leads to work arounds. VME power is not ideal for modern military and industrial applications.|
The market that current VME users are facing is centered around obsolete components and final time buys. Faced with “End of Life” (EOL) issues, designers are looking for alternative solutions to replace VME entirely. Though redesigns on substitute VME products have happened in some instances, it is not a sustainable solution as VME boards continue to completely sunset. Engineers are now basing their replacement systems on modern commercial-off-the-shelf (COTS) Ethernet I/O products and computers.
UEI’s modern Ethernet I/O technology backed by a 10-Year availability guarantee. UEI guarantees the availability of all RACKtangle (rack systems) and Cube series products for a minimum of 10 years. Unless you are specifically notified at the time of purchase, all hosted (PowerDNx) and embedded (UEIPAC) products will be available for repurchase for at least 10 years. We understand the investment you make by using our products and we ensure long-term product availability. Protecting customers from product obsolescence issues is nothing new at UEI.
|With smaller chassis sizes, shorter wiring, and intuitive software drivers, cost savings becomes very significant with UEI versus VME technology.||UEI offers support for all popular OSs, languages, and applications. UEI provides drivers for Windows, Linux, VxWorks, RTOSs, and more.|
|Software Support||COTS Production|
|Our patented DMAP™ Ethernet protocol ensures systems with thousands of I/O points are monitored / updated in less than a millisecond. Learn more in this paper.||All UEI's chassis are COTS products. We offer emergency replacements to get you back up and running immediately.|
Alleviate supply chain headaches of building commercial and military simulators due to product obsolescence and too many suppliers, all while improving the efficiency of their engineering team.
Co-designed over a dozen products on standardized UEI reliable, rugged, flexible platform, consolidated three systems into one (combined DAQ and avionics) while significantly reducing cabling/wiring and costly system inspections.
Reflective Memory is a method for sharing and synchronizing data in multiple chassis with VME (VERSA-Module Euro card) boards. A mainstay technology in both military and industrial I/O, Reflective Memory networks typically provide the deterministic timing required by real-time control systems and at the same time minimize the network load on the chassis CPU.
UEI’s patented DMAP™ alternative to Reflective Memory provides the same functionality but eliminates the requirement for dedicated memory boards by taking advantage of recent technology and in particular, speed advances in CPU, FPGA, DDR2 memory technologies. DMAP uses a simpler, less expensive architecture and uses a standard Ethernet technology as the communications link.
Interface adapters can be designed to preserve the existing cabling. Connect the interface board directly to UEI, and use the existing 96 pin cable!
