Unfortunately, the list of potential data thieves is nearly as long as the list of smart card applications. It runs the gamut from isolated hackers looking for glory or seeking free access to resources on up to organized crime, terrorists, industrial competitors and even angry ex-employees.

Die ECMA (European Association for Standardization Information and Communciation Systems, ehedem European Computer Manufacturers Association) hat in ihrem Standard 350” die Richtlinien für optische 30-GByte-UDO-Cartridges festgeschrieben. Damit besteht eine Grundlage für die Austauschbarkeit dieser Datenträger. UDO gilt als aussichtsreicher Kandidat für die Nachfolge der seit den neunziger Jahren in den Unternehmen häufig eingesetzten magneto-optischen (MO)-Datenträgern im Format 5,25 Zoll. UDO soll höhere Kapazitäen zu erheblich niedrigeren Kosten bieten.

Der Standard schreibt physische und logische Parameter für das UDO-Format fest. So unterscheidet die neue Norm zwischen wiederbeschreibbaren und so genannten True-Write-Once-Medien. Jede bietet eine Bruttokapazität von 15 GByte je Plattenseite. Für beide Arten von Datenträgern spezifiziert die Norm Datenformat, physikalische Anordnung der Spuren, thermo-optische Charakteristiken, Fehlerkorrekturcodes, Modulationsverfahren und vieles mehr. Sogar die Umgebung, in der die Cartridges gelagert werden, ist genau festgelegt.

Der Formfaktor von 5,25 Zoll stellt die Grundlage dafür dar, dass MO- und UDO-Medien in derselben Bibliothek vorgehalten werden können. Zusammen mit dem Umstand, dass künftige Laufwerksgenerationen abwärtskompatibel sein sollen, erleichtert das den Umstieg auf die neue Speichertechnik.

Zurzeit lassen sich mit den bei UDO eingesetzten blauen Lasern Kapazitäten von 30 GByte erreichen. Marktteilnehmer wie der britische Archivierungsspezialist Plasmon rechnen mit einer Verdopplung der Kapazität alle 18 bis 24 Monate. Bei den Medien der aktuellen ersten Generation seien Preise von 2 US-Dollar je Gigabyte zu erzielen — ein Fünftel des Gigabyte-Preises von MO-Medien.

SANTA CRUZ, Calif. — Startup Silicon Dimensions Inc. (SDI), which promises a unique set of design closure” tools for complex ICs, has announced its company launch and management team. Based in Marlborough, Mass., the company combines EDA and systems expertise.

SDI is preparing a product called Chip2Nite, which will help logic designers understand and plan for physical constraints and challenges. The company is backed by $3 million in venture capital funding.

With a wire-centric approach that addresses 180 nm and below design complexities, Chip2Nite introduces a new IC paradigm,” said Don Zereski, SDI president and CEO. By providing logic designers with access to vital information they never readily had before, Chip2Nite effectively is ending the long, dark era of design closure problems caused by insufficient information sharing.”

Zereski previously lead InfiniSwitch, a venture-backed startup. He also served as Groupe Bull's senior executive vice president, and held executive positions at Data General and Digital Equipment Corp. He will drive SDI's product launches, funding activities and other corporate initiatives.

The Class 12-capable design is based on the company's OMAP platform and puts an applications processor, digital baseband, analog baseband, power management, an audio codec and a single-chip Bluetooth device on a credit-card size board.

The reference design, called TCS3500, is a third-generation design, building upon the company's GSM/GPRS announcement last year, which was based on an OMAP730 processor. To meet the baseband-processing demands of Edge (Enhanced Data Rates for GSM Evolution), the company added a 'C55 DSP to the '730 and renamed it the OMAP850, said Tom Pollard, director of marketing for wireless chipsets at TI. The company worked with Comsys for the DSP elements at Layer 1 and also added multimedia support for a 2-megapixel camera with enhanced frame-buffer management and hardware accelerators.

We're entering with a compelling multimedia solution by Q4 '04 and we need an Edge product that will take advantage of all our technology,” said Pollard. Reference designs are becoming important to our business as it helps designers get to market faster,” he said, adding, reference designs are also getting more full featured with more integrated, such as Bluetooth, and daughtercard modules.”

Along with the '850 applications processor with digital baseband, the reference design includes the TWL3027 integrated analog baseband, power management and audio codec, a quad-band RF section from an as yet unnamed third party and TI's own BRF6150 Bluetooth chip.

The daughtercard components include a TNETW1230 802.11a/g-based wireless LAN card, an assisted-GPS card, a camera interface module and a keyboard interface module. Other support devices include a handset interface with color LCD, a debug board with interface cable and antennas.
