As the RFID technology market moves beyond early adopters, vendors and integrators are fielding customer questions about the security of RFID systems.
Concerns over RFID security were stoked last year when a team of university researchers in the Netherlands published a paper describing how RFID tags could provide a conduit for miscreants to launch attacks on back-end network infrastructure. But in most RFID systems, tags contain small amounts of fixed, read-only data, making them unlikely conduits for infecting the middleware and back-end databases that power RFID systems, according to many industry experts.
Poorly configured RFID systems have the potential to be targeted by hackers, but all it takes are rudimentary skills to properly architect and make an RFID network secure, said Patrick Sweeney, president and CEO of Odin Technologies, an RFID integrator in Herndon, Va. "If a network is set up with a base-level security configuration, there is no way those types of things can happen."...more  (0) Comments |
ADI Blackfin Outperforms ARM-Based Freescale I.MX Processors In EEMBC Benchmarks |

Analog Devices announced certified results for the Blackfin BF533 processor in a wide range of tests performed by the Embedded Microprocessor Benchmark Consortium (EEMBC). ADI’s Blackfin demonstrated strong performance in 11 EEMBC benchmark ratings, which test for specific capabilities in embedded communications, networking, consumer, office automation, automotive, industrial and digital entertainment applications. All of the tests were run using EEMBC’s “out-of-the-box” C code, which demonstrates Blackfin’s microprocessor and C compiler performance....more (0) Comments |

The digital signal processor (DSP) arena is moving towards multicore designs to solve a host of new problems. At present, Texas Instruments, the leader in the DSP market, fields a six-core IC. Recently, TI introduced two multicore DSPs for wireless infrastructure, including a six-core product. "The next 25 years of digital signal processing technology will literally integrate hundreds of processors on a single chip to conceive applications beyond our imagination," said Mike Hames, senior vice president for TI....more (0) Comments |

IGBT Tutorial: Part 1 - Selection |

Find out what an IGBT is and the tradeoffs you need to know about before making a selection. The insulated gate bipolar transistors (IGBTs) combines an easily driven MOS gate and low conduction loss, and is quickly displacing power bipolar transistors as the device of choice for high current and high voltage applications. The balance in tradeoffs between switching speed, conduction loss, and ruggedness is now being finely tuned so that IGBTs are encroaching upon the high frequency, high efficiency domain of power MOSFETs. In fact, the industry trend is for IGBTs to replace power MOSFETs except in very low current applications. Part 1 helps you understand the tradeoffs and helps with IGBT device selection, application and a relatively painless overview of IGBT technology. Part 2 provides an example walkthrough of IGBT datasheet information....more (0) Comments |

Multi-core processors are making the transition from the PCs to the embedded digital signal processors (DSPs), according Texas Instruments. "The next 25 years of digital signal processing technology will literally integrate hundreds of processors on a single chip to conceive applications beyond our imagination,” said Mike Hames, senior VP, Texas Instruments, speaking the company's Developer Conference (TIDC) in Dallas. Last year, AMD's chief technologist said something similar about the enormous potential of multi-core processors. According to Hames, hundreds of processors will be integrated on a single, three-dimensional chip and large-scale, parallel processing becomes standard....more (0) Comments |
