3U OpenVPX SBC module meets SWaP for mil-aero applications

Suited to extreme environments, the VF370 is an Intel-based 3U OpenVPX single board computer (SBC) module from Sundance Multiprocessor Technology. It is available in standard air-cooled and rugged conduction-cooled versions for and, in addition to mil-aero, it can be used for industrial control, automotive and UltraHD video and graphics processing applications.

The VF370 uses the Intel Atom E3900 series of embedded processors combined with Intel’s Cyclone FPGA technology to provide a flexible architecture for high reliability applications.

The VF370 has a single, dual or quad core Intel Atom processor operating at up to 2GHz for running post-processing software. An onboard SATA SSD provides fast booting and reliable high-performance storage for demanding applications while associated on-board peripherals include 4Gbytes of associated DDR memory, a real-time clock (RTC), elapsed time indicator (ETI), EEPROM and flash memory for user configuration data and logs.

The Intel Cyclone FPGA, with scalable logic and variable-precision DSP resources, facilitates the implementation of IP cores and/or custom logic for applications requiring real-time FPGA pre-processing. Combined with 2Gbyte of DDR3 memory, it supports algorithms with large memory size and bandwidth requirements.

The addition of a VITA 57 FMC site creates modular processing that facilitates a wide range of I/O requirements through the use of FMC mezzanine cards. The high pin count FMC connector connects to the FPGA through four high-speed serial interface (HSSI) lanes and 58 differential LVDS/LVTTL signals. An optional FMC I/O connector routes 32 differential pairs to the P2 VPX connector for backplane or rear I/O functionality.

An integrated graphic processor running at 650MHz enables greatly enhanced video encode and playback performance with UltraHD 4K display resolution on multiple independent displays for surveillance and other video-centric applications. Intel’s on-board Time Coordinated Computing Technology can synchronise networks of devices to within one microsecond, to improve the real-time deterministic behaviour of a system and Intel’s Trusted Execution Engine provides enhanced data and operations protection with fast cryptographic execution and secure boot features.

A configurable PCIe interface supports different OpenVPX profiles at Gen1 and Gen2 speeds for high data throughput capability. The VF370 typically operates as a VPX system controller but can also be a PCIe end-point module when plugged into a non-system slot. The VF370 board management supports Tier 1 IPMC functionality on the VPX management plane as per the VITA 46.11 specification. To simplify development and system integration, USB debug interfaces are provided for the Intel Atom embedded processor and the Cyclone FPGA.
