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.

OpenVPX — From Concept to Specification

The OpenVPX Industry Working Group, a 28-company team founded by Mercury Computer Systems, collaborated with a common goal and accelerated the completion of a system architecture specification for open system COTS suppliers and integrators to specify, design, and build multi-vendor interoperable solutions.

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.

Putting OpenVPX To Work

Before the advent of OpenVPX, designers of embedded systems took advantage of the extreme connectivity offered by VPX (VITA 46), but were faced with a virtually unlimited number of possible implementations. Specific choices for the control and data channel assignments for each slot, the backplane connectivity, and serial fabrics were often made somewhat arbitrarily to suit the particular needs of the current system. Although following the general framework of VITA 46, each system tended to be so unique that the boards and backplanes designed for one system were seldom usable in other systems, even from the same vendor.

OpenVPX/VITA-65 Serial RapidIO® GEN-2 Switch

Curtiss-Wright Controls Embedded Computing (Ottawa, Ontario, Canada) has introduced the OpenVPX™/VITA-65 compliant VPX6-6902 Serial RapidIO® (SRIO) switch card. This rugged 6U VPX board, available in both air- and conduction-cooled versions, combines Ethernet and SRIO switching in a single slot for management, control, and dataplane switching in high performance embedded military systems. Supporting both Gen-1 SRIO (1.25, 2.5, 3.125 Gbaud) and Gen-2 SRIO 6902 enables systems integrators to quickly and easily architect small to large high-performance systems that adhere to the VITA-65 OpenVPX™ systems specification.

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.
