GPU and FPGA go head-to-head - Story
November 16, 2020Today’s embedded-system designers have a great variety of processor types to select from, with FPGAs [field-programmable gate arrays] and GPUs [graphics processing units] adding their own various advantages and disadvantages for consideration in contrast to the more familiar CPUs [central processing units]. Understanding these characteristics and how FPGAs and GPUs stack up can help system integrators make the right choice when choosing and installing a processor, to be used either individually or in combination with other types of processors.

MACsec encryption extends the value of copper-based Ethernet LANs - Story
February 20, 2019
There is vastly more copper-based twisted-pair Ethernet infrastructure deployed on military and aerospace platforms than there is fiber-optic cable-based wiring. For one thing, the cost of copper cabling and its related connectors keeps being driven downward by the economies of scale brought about by its widespread use, helping to make it virtually ubiquitous. But fiber-optic cabling, until fairly recently, was the only practical choice for applications that required high-speed 10 Gbit/s connectivity. Driving demand for higher-speed Ethernet is the increased use of applications such as HD video surveillance on deployed platforms, resulting in ever-larger high-resolution file sizes.

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.

The commonality of COTS solutions for UUVs and UAVs - Story
April 13, 2017
Some time ago, when designers started thinking about unmanned undersea vehicle (UUV) applications, concerns were raised that the undersea environment might be so different or exotic that standard solutions would need to be significantly modified. To the surprise of many, however, it was found that there is significant commonality between unmanned aerial vehicle (UAV) and UUV environments. There are, to be sure, unique aspects to each type of platform, but in general, standard rugged military commercial off-the-shelf (COTS) embedded solutions are applicable to both.

Enabling Mounted Assured PNT with one COTS-based box - Story
October 27, 2016
Today's warfighter depends on GPS signals to acquire accurate position, navigation, and timing (PNT) data. There's a potential downside to dependence on traditional GPS, however: In some terrains, such as dense foliage or urban canyons, GPS signals can become degraded. GPS receivers can also come under attack from adversaries through jamming or spoofing. Given how critical GPS capabilities are for military services, next-generation PNT technologies are emerging to address vulnerabilities from emerging threats and field conditions.

Case study: EFV keeps pace with Ethernet to actualize net-centric warfare - Story
August 14, 2009
The success of net-centric warfare is dependent on fast, secure communications technology - specifically Ethernet. To meet the military's demands for Ethernet-enabled vehicles, Ethernet switches and routers need to be increasingly rugged and capable of meeting future network requirements. A case study of the USMC's Expeditionary Fighting Vehicle (EFV) with its Tactical Switch Router (TSR) exemplifies this trend.
