The company has never made a profit. Losses were $10.1 million in 1998 and $41.1 million in 1999, before reaching $43.4 million for the first half of 2000. Transmeta also has $120 million of long-term debt.

Both companies declined to provide pricing for their chipsets; each instead cited total Bluetooth bill of materials based on implementing their respective solutions. Infineon said a BOM with the BlueMoon I will be less than $17, while TI claims a BOM of less than $10 with its solution.

PARK RIDGE, Ill. — A draft specification released describing an automotive version of the IEEE 1394 bus is moving forward as a high-speed serial interface for future vehicles, and as a potential competitor to the fiber-optic Most bus backed by several European car makers. Key to the success of the 1394 bus will be support from the powerful Automotive Multimedia Interface Collaboration (AMIC), an industry group that includes 12 of the world's biggest auto makers.

AMIC has met with representatives from the 1394 Trade Association and the IDB Forum in an effort to hammer out a specification that would put IEEE 1394 serial buses on board everyday vehicles. If they can reach agreement, the bus would provide a high-speed connection for the efficient transmission of data in vehicles. The agreement would also enable consumers to plug handheld electronic devices, such as camcorders and DVD players, into vehicle networks.

The availability of such bus technology is considered critical because of the increasing amount of digital data that now passes through vehicles. In particular, automotive audio and video systems will require high-bandwidth buses to handle huge data streams in the future.

The 1394 serial interconnection is said to be a strong candidate for such applications because of its high speed and compatibility with consumer electronics. IEEE 1394 is already used in more than 10 million camcorders and eight million PCs, as well as in millions of printers, scanners, video games, and mass-storage devices. It offers speeds of 100, 200, and 400 Mbits/second.

One of the big things driving 1394 is that it does very well with video,” said Arlan Stehney, executive director of the IDB Forum (Pittsburgh), a cross-industry group concerned with networking and electronics standards. So it's well-suited for rear-seat entertainment systems in minivans and sport utility vehicles.”

The meeting between AMIC and the standards groups raises questions about the future of automotive network buses. AMIC is currently drafting the first release of a specification that will include a low-speed CAN (controller-area network) bus, and possibly a high-speed fiber optic bus. Until recently, the fiber-optic Media Oriented Systems Transport (Most) bus was the leading high-speed candidate for endorsement by AMIC.

But OEM engineers and representatives from the 1394 Trade Association and the IDB Forum this week introduced an 80-page draft spec of the so-called IDB-1394 bus, which could be thrust into a prominent position with AMIC.

The AMIC's endorsement could be critical for the technology, because AMIC counts as members BMW, DaimlerChrysler, Ford, Fiat, General Motors, Honda, Mitsubishi, Nissan, PSA Peugeot-Citroen, Renault, Toyota and Volkswagen. The group of manufacturers has stated that it wants to standardize electrical architectures because such architectures could lead to simpler implementation of navigation systems, CD players, video screens, digital radios, cell phones, and a host of other devices in their vehicles. Car manufacturers now complain that they must often reengineer vendor products, which are not designed to any specific standard. As a result, they lose valuable development time and risk falling behind the rate of innovation in the electronics industry.

Hitachi and Rambus, however, have often been at odds. Hitachi initially declined to pony up royalties for Rambus' SDRAM and DDR interfaces, which prompted Rambus earlier this year to sue Hitachi for patent infringement, and later seek to bar the import of Hitachi-made DRAMs and SDRAM controllers to the United States by filing a complaint with the U.S. International Trade Commission (ITC). Hitachi eventually capitulated and agreed to license and pay royalties to Rambus for SDRAM, RDRAM and DDR interfaces, until the joint-venture company takes control of Hitachi's DRAM operations.

Despite the mixed opinions among Hitachi and NEC management over Rambus, early signs indicate that the joint-venture DRAM company will take a conciliatory position with Rambus. The joint-venture, which will be headed by Kenji Tokuyama, NEC's former memory division boss, is trying to cast itself as an independent entity eager to get off the ground without a hitch as it aims to nab a 20 percent share of the DRAM market.

Asked about the new company's stance on Rambus' royalty and licensing campaign, an NEC spokesman said, My understanding is that they will probably sign something by the end of the year.” The new company doesn't want a legal confrontation,” he added. It just wants to get the business established and up and running as smoothly as possible.”

The parent companies may also wish to avoid a repeat of Hitachi's bout with Rambus. Even though the new DRAM company will be an independent operation on paper, it has no fabrication facilities of its own and will rely on NEC and Hitachi for manufacturing capabilities. Any action by Rambus that would try to stop the import of SDRAM or DDR SDRAM into the United States in the absence of an agreement could pose a threat to the parent companies' manufacturing operations. Rambus pursued that route against Hitachi and one of its biggest customers, Sega Enterprises, which uses Hitachi's SDRAM controllers in its Dreamcast game console, earlier this year when it appealed to the ITC. Rambus recently lodged a similar complaint with the ITC against Hyundai.

If the joint-venture DRAM company decides to pay the Rambus tax, it will steer clear of the separate legal battles that now pit Rambus against DRAM makers Micron, Hyundai and Infineon. After resisting Rambus' attempts to collect royalties on SDRAM and double-data-rate SDRAMs, these chip makers separately filed lawsuits that accuse Rambus of antitrust violations and question the validity of its patent portfolio. Rambus has also been on the warpath, filing lawsuits accusing these DRAM makers of patent violation.
