6U OpenVPX Rugged Single Board Computer

GE Intelligent Platforms (Charlottesville, VA) has announced the SBC622 rugged 6U OpenVPX-compliant single board computer. At 2.53GHz, the SBC622’s Intel Core i7 processor is 30% faster than its predecessor, with up to 8 GBytes of soldered DDR3 SDRAM with ECC and a high bandwidth 10 Gigabit Ethernet I/O fabric subsystem. Customer flexibility to configure the SBC622 according to the precise requirements of the application is delivered via two onboard PCI-X® PMC/XMC mezzanine expansion sites. Provision for a higher degree of failsafe operation is delivered through the SBC622’s onboard BIOS flash which can be

optionally backed with a second flash device.

6U VPX Load Board

Elma Bustronic Corporation (Fremont, CA) has introduced a new 6U VPX Load Board that helps confirm the chassis meets the VITA 46/48 power specifications for VPX and aids in locating hot spots within the enclosure. The 6U VPX load card features a microcontroller-based stepped load control to 100W maximum. Go-No-Go indicators are present for 3.3V, 5V, 12V, +12V_Aux, -12V_Aux and 3.3V_Aux. The rotary switch selects the voltage setting while pushing the ON switch will cycle between different power levels shown on the LED display. The set load power levels are saved in EEPROM. Other features include a power reset button (to minimum level) and a SYSRESET signal on the two test point outputs.

Forced Air-Cooled Enclosure

Extreme Engineering Solutions (X-ES) (Middleton, WI) is now shipping the XPand4200, a sub-1⁄2 ATR, forced air-cooled enclosure for conduction-cooled modules. The system measures 4.88" (W) × 6.0" (H) × 13.5" (D) and weighs 8.8 pounds. The XPand4200 has an optional removable memory module attachment that supports the XPort6191 Solid State Disk (SSD) removable storage module, with 64 GB of storage capacity. With the memory module attachment the height increases to 7.62" and the weight to 11.1 pounds. Up to six conduction-cooled, 0.8" pitch 3U VPX, 3U cPCI, or power supply modules can be configured into the XPand4200. Additionally, the XPand4200 can be configured to meet custom I/O requirements with conduction-cooled PMC / XMC modules available from X-ES or third parties.

Two-Slot OpenVPX Development Platform

Elma Electronic Systems Division (Fremont, CA) has released a new two-slot VPX/OpenVPX test and development platform that accommodates both 3U and 6U boards via a shelf divider. The new E-Frame Series enables developers to power up one or more VPX blades under test and interconnect the J1 fabric connections to emulate the user’s application. The use of a standard VPX RTM (rear transition module) plugged into the back provides access to the J0, J2, J3, J4, J5 and J6 connectors, while simultaneously accessing high-speed signals in the J1 connector, routed out the side of the backplane. Each slot’s J1 “A” channel is broken out into 16 SMA connectors and the “B”, “C” and “D” channels into four SATA2 cable headers (12 total per slot).

IPv4/IPv6 Gigabit Ethernet Switch

The new Kontron (Poway, CA) Gigabit Ethernet Switch VX3910 offers 3U VPX (VITA 46.x) and OpenVPX™ (VITA 65) platforms enterprise-class switching functionality with a total of 28 Gigabit Ethernet ports and advanced management features. The non-blocking fully managed L2/L3 Gigabit switch, Kontron VX3910, with its 20x Gigabit ports to the backplane, offers the highest port density for the implementation of various network topologies in 3U appliances. Four additional 2.5-Gigabit ports to the backplane simplify a redundant system architecture with multiple switches with no single point of failure. The four 1000 Base-T uplinks on the front panel, one dedicated for out-of-band management, expand the range to a total of 28 ports. The new Kontron Gigabit Ethernet Switch VX3910 is available in an air-cooled version for ambient temperatures from 0°C to +55°C and in a rugged conduction-cooled version for the extended temperature range from -40°C to + 85°C.

Using the Intel® Architecture in High-Performance Military Embedded DSP Applications

Historically, processors from the PowerPC® family, now known as Power Architecture® processors, have been the dominant choice for implementing Digital Signal Processing (DSP) in high-performance embedded military applications that take advantage of open-system commercial off-the-shelf (COTS) products. These applications include radar, signal intelligence, sonar, and image processing. Today, however, beginning with the dual-core Intel Core™ i7 processors, the low-power, high-performance advantages of the Intel architecture processor technology can be used for the first time to design DSP engines for the rugged deployed COTS signal processing space.

In the early 1990s, systems were implemented largely with specialized processors such as the Intel® i860 processor, the Texas Instruments 320C40, and the Analog Devices SHARC®. These processors were popular because of their floating-point performance.

Protecting COTS Military Electronics From Shock and Vibration

Military systems represent extreme environments for COTS electronic equipment. Many systems involve multiple enclosures, often from different suppliers. Equipment layout, the selection of racks, whether isolation is used, and how the electronics are “housed” can vary widely. There are no standards regarding maximum allowable shock and vibration levels. Design factors are often based on estimates of equipment fragility and expected loads, both of which can be uncertain.

Let the Show Begin

VPX is like a three act play. Act one was the launching of a new high density platform for critical embedded computing applications. Leveraging the wildly popular VMEbus in 3U and 6U Eurocard formats, VPX added the capability of using high speed serial switch fabric technologies such as Ethernet, PCI Express, serial RapidIO, and others, that can be configured in various backplane topologies. VPX also greatly increased the number of backplane pins to handle more data traffic and user I/O making it more effective for today’s applications.

Transitioning to OpenVPX for Next-Generation C4ISR Systems

VPX systems offer tremendous performance for the Mil/Aero market, including naval, airborne, and ground-based computing systems. The architecture provides an unprecedented combination of bandwidth, user IO, and rugged design, in both a 3U and 6U Eurocard format. The new OpenVPX initiative has opened up new definitions for VPX system interoperability, including defined module profiles, slot profiles, backplane & chassis configurations, secondary expansion fabrics and control planes, and higher speed fabric options.
