Optimizing avionics reliability with dissimilar redundant architectures - Story
December 06, 2018
The potential consequences and acceptable probability of failure of an avionics system dictate the Design Assurance Level (DAL) that must be met in order for it to be certified for flight. The key computing elements of a system - such as the single-board computers (SBCs), graphics cards, and operating systems built into a flight-control computer or flight display - must all be designed with safety in mind and endure stringent testing to prove they can meet the required DAL. ARP4754 (Guidelines for Development of Civil Aircraft and Systems - Figure 1) is used by avionics designers as they allocate functions to systems and assign DALs to hardware and software for their safety-certifiable systems.

Milestone in abstracting the hardware: Realizing the promise of FACE - Story
October 17, 2018
The Future Airborne Capability Environment (FACE) Consortium, part of The Open Group, was formed to establish a standard common operating environment to ?support portable capability-based applications across Department of Defense (DoD) avionics systems. Key to the common operating environment envisioned by FACE is the definition of an interface for operating systems and board support packages (BSP) that enables the hardware portion of a system to be abstracted, greatly increasing the portability and reusability of software applications. With the wide adoption of FACE, system integrators can reap tremendous benefits in interoperability and cost.

Advances in switching bring rugged 1/10 GbE networking to embedded platforms - Story
September 07, 2018
As advanced network features and increasing speeds are added to next-generation rugged embedded switches, these products become even more useful for military applications by helping to reduce system size, weight, power, and cost (SWaP-C) through a reduction of cabling and the use of Layer 3 switches for basic network routing duties.

Cooling the beast: Heat-dissipation techniques for next-gen processors - Story
August 29, 2018
The good news: Newer-generation processing devices offer hugely boosted capability for military applications such as airborne data processing, shipboard electronics, or ground vehicle systems. The bad news: Newer-generation processing devices offer much more capability. Is this really both good news and bad news? In a word, yes.

Bringing VxWorks support to Intel Xeon D-based EW systems - Story
August 07, 2018
The advantages that the Intel Xeon processor D-1500 product family brings to compute-intensive embedded electronic warfare (EW) system designs is clear. These 8-/12-/16-core devices deliver enhanced performance at low power, making them suitable for use on rugged open-architecture modules designed for deployment in harsh environment applications including electronic warfare (EW) and command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR). These system-on-chip (SoC) devices make large numbers of x86 processing cores readily available for embedded defense applications.

The state of cyber resiliency metrics on embedded systems - Story
August 01, 2018
The ability of an embedded system to identify, prevent, and respond to cyberattacks intended to disrupt its operational capabilities is defined by measuring its level of cybersecurity and cyber resiliency. The concept of cyberattacks can refer to either electronic warfare (EW) like signal jamming or to cyberwarfare, for example, such as sending malformed packets to disrupt the system. How do the metrics used to measure a system's cyber resiliency relate specifically to embedded systems, and what are the special considerations that embedded-system designers must undertake when applying cyber resiliency metrics?

A fully integrated COTS approach for PNT to ground vehicles in GPS-denied environments - Story
June 07, 2018
Growing awareness of the potential vulnerabilities introduced by the military's dependence on GPS data has driven demand for new deployed approaches for detecting threats to GPS and providing position, navigation, and timing (PNT) information to the warfighter in GPS-denied environments.
