6U VPX GPU
6U VPX information
6U VPX video graphics modules supporting VPX-REDI and OpenVPX standards. WOLF’s 6U VPX modules include advanced NVIDIA GPUs and Xilinx FPGAs, which provide video output, image and data processing, video encoding to HEVC and AVC, and video capture.
High-speed GPUs and FPGAs provide the processing power required for high-performance computing (HPC) and artificial intelligence (AI) tasks.
VPX refers to three VITA standards:
– VITA 46 (base, 2007): the basic electrical and mechanical specification of the VPX
– VITA 48 (REDI, 2010): increased support for high-density electronic modules
– VITA 65 (OpenVPX, 2010): addressing interoperability
The VPX standard defined in VITA 46 is a scalable backplane technology designed specifically for critical high-speed embedded systems.

The VITA 46 working group was first established in 2003. At that time, VMEbus systems (first introduced in 1981) were widely used. VME systems used a parallel VME bus with a maximum bandwidth of 320 Mbytes/second (as defined in VITA 1.5, released in 2003). The newer VPX standard was defined to use the latest in serial switching structures, which provided a much higher maximum bandwidth. VPX board interconnects are high-speed MultiGIG RT connectors that support high-speed serial buses of 10 Gbps or more. The 3U VPX cards use 3 connectors (P0 to P2), while the 6U VPX cards use 7 connectors (P0 to P6). P0 is reserved for system control and power signals. P1 and P2 are used for high-speed serial bus and user I/O signals. In a 6U VPX, the remaining connectors (P3 to P6) are used for user I/O.
The VPX specification was extended in VITA 48 (VITA REDI, Reinforced Enhanced Design Implementation) to support the increased operating power of high-density electronic modules by defining mechanical design requirements to support improved cooling methods. VPX REDI also sets standards for the use of ESD covers on both sides of the plates.
OpenVPX (VITA 65) is a system-level VPX specification designed to address interoperability between VPX boards and multi-vendor backplanes.
