Embedded.com - Protecting FPGAs from power analysis security vulnerabilities - 0 views

  • Recent advances in the size and performance of FPGAs, coupled with advantages in time-to-market, field-reconfigurability and lower up-front costs, make FPGAs ideally suited to a wide range of commercial and defense applications [6]. In addition, FPGAs generality and reconfigurability provide important protections against the introduction of Trojan horses during semiconductor manufacturing process[8]. As a result, FPGA applications increasingly involve highly-sensitive intellectual property and trade-secrets, as well as cryptographic keys and algorithms [7].

DNA-assisted solution processing for high-performance thin-film transistors - 0 views

  • Single-walled carbon nanotube (SWCNT)-based thin film transistors (TFTs) could be at the core of next-generation flexible electronics – displays, electronic circuits, sensors, memory chips, and other applications that are transitioning from rigid substrates, such as silicon and glass, to flexible substrates. What's holding back commercial applications is that industrial-type manufacturing of large scale SWCNT-based nanoelectronic devices isn't practical yet because controlling the morphology of single-walled carbon nanotubes is still causing headaches for materials engineers.

Icosatetraped Robot Walks On 24 Soft Legs | BotJunkie - 0 views

  • Icosatetraped does, in fact, mean “twenty-four legged.” I’m not sure how to inject “soft” into that word (icostatetrasquishaped?), but this robot does have 24 soft legs. Or rather, 8 legs are soft (and moving) at any one time, while the other 16 are pressurized to carry the weight of the bot. It can move at about 1 meter per minute, which isn’t especially fast, but who cares, look at all of those little legs go! Made from plastic medical tubing, particle board, a bunch of solenoids, a Mac Mini, and some 24 volt rotary vane compressors salvaged from Gulf War nerve gas detecting equipment, this is about as DIY as it gets, and it’s awesome.

  • The IEEE has launched a new Web site that consolidates information about smart electric grids from it various societies. The portal is one of many activities from an IEEE smart grid initiative coordinating the organization's work on the transition to digital, networked power systems and services. The smart grid is "so interdisciplinary," said Wanda Reder, chair of the IEEE Smart Grid Task Force and former president of the IEEE Power & Energy Society. "We have the gamut covered in technical interests, but we needed a way to facilitate communications between our many entities to link information on all the conferences, papers and standards we have in this area," she added.

Leveraging FPGA and CPLD digital logic to implement analog to digital converters - 0 views

  • Ted Marena of Lattice Semiconductor Corp., points out that designers of digital systems are familiar with implementing the 'leftovers' of their digital design by using FPGAs and CPLDs to glue together various processors, memories, and standard function components on their printed circuit board. In addition to these digital functions, FPGAs and CPLDs can also implement common analog functions using an LVDS input, a simple resistor capacitor (RC) circuit and some FPGA or CPLD digital logic elements to create an analog to digital converter (ADC).

Ensuring the thermal integrity of your IC package/PC board design | Industrial Control Designline - 0 views

  • You just built a breadboard of your expert design. You did all the simulations needed before going to layout, and reviewed the manufacturer's suggested techniques for a good thermal design for the particular package chosen. You even did your due diligence in going through the initial thermal analysis equations on paper to be sure not to exceed IC junction temperatures with a comfortable margin. But wait, you turn on the power and the IC is pretty hot to the touch. You are uncomfortable with this (not to mention the concern of your thermal experts and reliability people). Now what do you do?

IEEE Spectrum: Robosoft Unveils Kompai Robot To Assist Elderly, Disabled - 0 views

  • French service robotics company Robosoft has introduced a robot called Kompaï designed to assist elderly and disabled people and others who need special care. The mobile robot talks, understands speech, and can navigate autonomously. It reminds people of meetings, keeps track of shopping lists, plays music, and works as a videoconference system for users to talk with their doctors, for example. The video below is pretty awesome. It shows a senior at Broca Hospital, in Paris, interacting with the robot after receiving only a few minutes of training. The man asks the robot about the time, date, and whether he has any appointments that day; Kompaï gives answers in a computerized voice.

IEEE Spectrum: Evidence for Bacterial Electrical Networks - 0 views

  • Experimental microbial fuel cells could turn bacteria into batteries that generate electricity from biomass. The key to this technology is the ability of bacteria to transfer electrons to their surroundings—for example, to the anode of a microbial fuel cell. But if the organisms have to be in direct contact with the anode, such devices would have to have extremely large surface areas. Researchers from Aarhus University, in Denmark, report today in the journal Nature that bacteria appear to conduct electricity while separated by several millimeters, at least a thousand times as far apart than previously demonstrated. The naturally occurring electric currents, if confirmed, would allow bacteria spaced at least 12 millimeters apart to communicate electrically. The discovery might lead to new paths to treating infection and a better understanding of microbial ecosystems.

Circuit-protection strategies for improving LED reliability and lifetime - 3/18/2010 - EDN - 0 views

  • LED luminaires require precise power and heat management because LEDs convert most of the electrical energy they receive into heat rather than light. Without adequate thermal management, this heat can degrade the LED's life span and affect color output. Also, LEDs can fail short because they are silicon devices, so they may require fail-safe backup in the form of overcurrent protection. Resettable PPTC (polymeric-positive-temperature-coefficient) circuit-protection devices have demonstrated their effectiveness in a variety of LED-lighting applications. Like traditional fuses, they limit current after they exceed specified limits. However, unlike fuses, PPTC devices can reset after the fault clears and the power cycles.

Intel launches PCI-enabled 'SoC' | Audio DesignLine - 0 views

  • Intel has announced that is developing a system-on-chip for embedded applications based around its Atom processor core. However, it appears the SoC will be of a fixed design with a PCI Express bus interface to which system-level customers can attach their own or third-party chips. Similarly it appears that Intel will manufacture the system-chip internally rather than allowing a foundry to make the chip, or add its customers' IP to the design. Doug Davis, corporate vice president and general manager of Intel's embedded and communications group, disclosed details of the "Tunnel Creek" SoC during his keynote speech on Wednesday (April 14) at the Intel Developer Forum, in Beijing China.

Embedded.com - Timing Closure on FPGAs - 0 views

  • Have you ever written code that behaves correctly under a simulator only to have intermittent failures in the field? Or maybe your code no longer functions properly when you compile with a newer version of your tool chain. You review your test bench and verify 100 percent complete test coverage and that all tests have passed with no errors--yet the problem stubbornly remains. While designers understandably place great emphasis on coding and simulation, they often have only a nodding acquaintance with the internal workings of the silicon within an FPGA. As a result, incorrect logic synthesis and timing problems, rather than logic errors, are the cause of most logic failures. But writing FPGA code that creates predictable, reliable logic is simple if designers take the right steps. In FPGA design, logic synthesis and related timing closure occur during compilation. And many things, including I/O cell structure, asynchronous logic and timing constraints, can have a big impact on the compilation process, varying results with each pass through the tool chain. Let's take a closer look at ways to eliminate these variances to better and more quickly achieve timing closure.
