But the discussion must recognize the tension developing between, on one side, the European Union, industry body SEMI, research institutes like IMEC and on the other side the commercial chip companies such as Infineon, NXP and ST.

Each base module contains two PowerPC 7400 processors and uses high-bandwidth RACE++ connections to communicate with processors on other base modules. The systems come with a full set of real-time software for image -and signal-processing applications, including an integrated development environment, multiprocessor communications libraries and algorithm libraries hand optimized for the AltiVec vector-processing engine.

Applications for the systems include digital television, medical imaging modalities such as multislice computed tomography, digital X-ray and interventional imaging; military applications using the peripheral component interconnect environment (PCI) from sonar to ground stations; and wireless communications.

Volume pricing starts at $13,000. The product is available now, with volume production planned for February 2001.

WASHINGTON — Extensive digital TV field tests conducted last summer to compare the VSB and Cofdm modulation schemes showed that VSB provides better overall reception.

The test results, presented Thursday (Jan. 11) at a closed industry meeting of broadcasters sponsored by the Association for Maximum Service Television (MSTV) and National Association of Broadcasters (NAB), also showed that neither vestigial sideband (VSB) nor coded orthogonal frequency division multiplex (Cofdm) performed well for indoor DTV reception or for so-called pedestrian reception” portable DTV applications.

In fact, the test results really replicated what FCC's Office of Engineering and Technology already predicted a year ago in their theoretical analysis,” said an attendee of the meeting, who spoke on the condition of anonymity. The purported advantage of Cofdm simply didn't appear on the field tests,” he said.

Backers of Cofdm modulation heatedly disputed that conclusion, arguing that the testing was flawed because it used a European-made Cofdm receiver that was not set up to handle U.S. power levels or adjacent channel interference, which is considered worse in the United States than in Europe.

A spokesman for Sinclair Broadcasting, a leading proponent of Cofdm, attributed the deficiencies to gross negligence.” The report said European equipment had to be configured for the MSTV test because there are no Cofdm systems currently employed in the U.S.”

With conventional lithographic tools on the market, the minimum feature size and depth of field is limited by the wavelength of light used,” Gilson said. No such fundamental resolution limit exists for the new technology.” Last year, Gilson told SBN that the company's technology creates an interferometric pattern of two light paths in order to pattern images with smaller feature sizes. He said the technology could use optical lenses with numerical apertures as low as 0.5 and create feature sizes as low as 0.10 micron (see April 26, 2000, story).

Mulith today said it is currently eliciting offers for technology licenses, joint ventures, or outright acquisition of its RIF lithography and metrology technology.

Wireless technology still has huge challenges ahead of it according to Intel’s chief technology officer, Justin Rattner.

Speaking to EE Times recently, Rattner noted that in an age where everything that computes will connect, the industry would have to overcome several roadblocks and push for a lot of improvements before the technology was in any way ready to be entirely pervasive.

We still build a lot of the wireless radios using techniques that date back about 120-130 years,” said Rattner, adding that the industry was only just starting to grapple with optimizations that give users the wireless experience they want without killing their battery.
