Unlocking the multi-core potential of Xpedite7674

Extreme Engineering Solutions (X-ES) have  announced the integration of its secure-by-design Xpediate7674 board with the LynxSecure Safety Bundle (LSB) from Lynx Software Technologies,  a company that specialises in mixed critically and MILS system development.

LSB is an open system architecture solution that unlocks the potential of the multi-core processors such as the Intel Xeon D to deliver 2nd generation Integrated Modular Avionics (IMA).

LynxSecure Safety Bundle allows developers to create sophisticated modular avionics designs that consolidate mixed-criticality applications, RTOS’s, Embedded Linux, and bare metal applications onto multi-core processors and across federated and networked systems. The LynxSecure Separation Kernel is the unique foundation that keeps these modules completely independent from each other, only allowing them to utilise defined hardware resources such as cores, memory, and devices.

Developers can update each secure and safe module independently without affecting the other modules, even when certified. This second generation IMA approach allows the creation of safer, more complex systems, using multi-core hardware while reducing overall certification costs of the entire system. Moving traditional single core avionics applications to a multi-core CPU has never been easier than with LSB.

X-ES’ 2nd generation IMA development platform facilitates rapid technology insertion and modular system component refreshes, enabling suppliers to deliver and monetise system upgrades well into the future, while reusing existing code and re-hosting legacy applications in the IMA environment.


The XPedite7674 is a high-performance, 3U VPX-REDI, single board computer based on the Xeon D processor. The Intel Xeon D processor can provide up to 16 Xeon®-class cores in a single, power-efficient System-on-Chip (SoC) package with native extended temperature support for up to 12 core-count SKUs.

The XPedite7674 provides secure network interfaces by providing one 1000BASE-X Gigabit Ethernet interface from the FPGA and passing two CPU 10 Gigabit 10GBASE-KR Ethernet interfaces through the FPGA. It also supports a user-configurable Xilinx Kintex UltraScale FPGA.

LynxSecure Safety Bundle

An open system architecture that unlocks the potential of multi-core to deliver 2nd generation Integrated Modular Avionics (IMA) solutions.  LSB integrates the complete range of system development services for platform suppliers in order to build, deploy and sustain their IMA platform.

It enables system integrators to leverage modern multi-core hardware to significantly reduce SWaP (size weight and power) by consolidating multiple Line Replaceable Units (LRUs) onto a single platform.

This revolutionary solution securely integrates four key capabilities:

  • LynxSecure, the world’s only truly secure-by-design separation kernel hypervisor
  • LynxOS-178, a DO178C DAL A certified RTOS to run safety critical application workloads
  • Embedded Linux based on the Buildroot technology for non-critical application workloads
  • Luminosity, an Eclipse based Integrated Development Environment

LynxSecure Safety Bundle (LSB) integrates the complete range of system development services for platform suppliers in order to build, deploy, and sustain their Integrated Modular Avionics (IMA) platform.
