Latency, or the time between input and output, can be very important, depending on the application. For processing of communications intelligence (COMINT) like audio conversations, text data and the like, relatively long latency is tolerable. For applications like Radar and Electronic Warfare (especially Digital Radio Frequency Memory or DRFM), just a small amount of latency is problematic, due to the necessity of quick response times.
Similarly, these demanding applications require very high bandwidth (throughput) due to the volume of data involved. Low latency without high bandwidth (and vice versa) is a waste of performance, as it won’t deliver mission success.[Continue reading →]

To perceive is to assign meaning to what we see, hear, touch, taste and smell. Similarly, perceptual computing offers users a more natural way to interact with machines. Today's platforms have the ability to go well beyond simple facial recognition, which is becoming quite common today as a way to replace passwords. In fact, recent developments in software technology made practical by advanced graphics processing units (GPUs) are expanding perceptual computing to new levels of functionality in embedded applications.[Continue reading →]

The ability to access accurate, real-time information across secure data links is a cornerstone of any successful military campaign. This ability is especially needed today given the requirement of the command-and-control center to communicate directly and instantly with soldiers in the field via both voice and data. What should be a strategic and tactical advantage, however, is only as good as the ability of advanced wireless technology to navigate a web of complex radio frequency (RF) and signal-processing technologies and to render a seamless, reliable, and secure communications network that delivers the right information at the right time in an ever-more-challenged RF spectrum.[Continue reading →]
It is the purpose of this primer to instead describe digital oscilloscopes, which have for practical purposes replaced their analog predecessors in the vast majority of applications. Covered here is a short description of the oscilloscope's origins, its transition from analog to digital, types of digital oscilloscopes and their major subsystems, key benchmark specifications, and measurements.
Whether analog or digital, the oscilloscope is a versatile piece of test equipment. Even though its basic function is to measure and display voltage, its capabilities are vastly greater. They range from automation of the measurements described here, as well as signal detection and analysis in commercial and defense systems, and a wide array of others.[Continue reading →]
Using Computational Fluid Dynamics (CFD) is no longer relegated to the realm of the specialist. A new class of CFD analysis software is proving to be highly effective at performing heat transfer analysis, enabling mechanical engineers to accelerate key decisions at their workstations and without the need for CFD specialists. Embedded into the MCAD environment, this intuitive process allows designers to optimize a product during the design stages reducing manufacturing costs across a wide range of mechanical designs and systems.[Continue reading →]

LAKE BUENA VISTA, Fla., July 24, 2012 -- Video service providers are increasingly turning to Digital Adware for their new modular ad insertion platform, AdSync. Launched last year, AdSync presents small and mid-sized video providers with an affordable digital ad insertion solution, allowing them to maximize profitability from local ad sales.
"The ability to insert ads into digital cable and IPTV platforms has always been available, but the cost of the equipment and licensing fees required has put it out of reach for many smaller carriers," said Brian Stuart, President of Digital Adware. "AdSync is not only priced considerably lower than products of its kind, but it also facilitates splicing and multiplexing functions, eliminating an array of licensing fees, offering a true one box solution."[Continue reading →]
Washington, D.C.. STM Group, Inc. has announced today, at the Satellite 2012 tradeshow in Washington D.C., that it is now shipping its SatLink® family of VSATs and Hubs with support for the new DVB-RCS2 standard for general availability. STM is the first company in the industry to support the "RCS2" standard. In June of 2011, STM also lead the way with the first public demonstration of the major high-performance features in the new RCS2 standard, just a few months after approval by the DVB organization.
DVB-RCS2 provides for higher order modulation and coding along with many other elements contributing to much higher throughput, better bandwidth efficiency, and improved link availability relative to legacy VSAT systems. Modulation and coding from QPSK 1/3 up to 16QAM 5/6 is provided for TDMA burst mode carriers with Adaptive Coding and Modulation (ACM) controlled per burst for each VSAT. The other elements include a 16-state Turbo Code FEC and highly efficient Return Link Encapsulation (RLE) for IP packets imposing about 2% overhead.[Continue reading →]

With mission critical software, development teams are tasked with looking for ways to accelerate innovation, improve product value, and lower software change costs. This white paper shows how Deos™, a time and space partitioned RTOS, allows this by providing the ability to decompose the software system into discrete, separately verified, binary re-useable components. In short, Deos provides tools and technologies to help a development team reduce the fear of post deployment changes and improvements that often grip mission critical projects.[Continue reading →]
SDR (Software Defined Radio) has revolutionized electronic systems for a variety of applications including communications, data acquisition and signal processing. This handbook shows how DDCs (Digital Downconverters) and DUCs (Digital Upconverters), the fundamental building blocks of SDR, can replace conventional analog receiver designs, offering significant benefits in performance, density and cost.
In order to fully appreciate the benefits of SDR, a conventional analog receiver system will be compared to its digital receiver counterpart, highlighting similarities and differences. The inner workings of the SDR will be explored with an in-depth description of the internal structure and the devices used. Finally, some actual board- and system-level implementations and available off-the-shelf SDR products for embedded systems will be described.[Continue reading →]
To realize the full potential of multicore systems, many usage scenarios require using multiple secure computing domains, often managed by different operating systems, on the same physical device. This can be accomplished by dividing the cores, memory and I/O devices of a system into secure, logical partitions. The partitions need to operate independently of each other, and operating systems must be able to access and manage the hardware resources belonging to the partition with little or no overhead.[Continue reading →]

Migrating code to multi-core processors has become a major design decision for embedded developers. To help simplify migration efforts, operating system vendors have introduced solutions for asymmetric multiprocessing (AMP), symmetric multiprocessing (SMP), and bound multiprocessing (BMP). However, once the basic multiprocessing model is chosen, the real work begins. It isn’t enough to get software to run on a multi-core processor — the key to success is optimizing the software to make full use of all the processor’s cores.
This paper examines various techniques for optimizing code on multi-core processors. It addresses threading models for multiple concurrent tasks and parallel processing for increased performance. It discusses how to minimize lock contention with mutexes and semaphores by engineering the appropriate levels of lock granularity. Finally, the paper explores methodologies for resolving performance problems that result from inefficient use of CPU cache. [Continue reading →]
