Secretive Transmeta finally unveils Crusoe

Crusoe, which will be the brand name for Transmeta's first family of mobile chips, will bring increased power and longer battery life to a range of mobile devices used to access the Internet, from full-fledged laptop computers to new types of emerging devices like Web pads and handheld computers, promised David Ditzel, Transmeta's CEO.

The key to Crusoe's capabilities is its "code morphing" technology, which converts instructions written for x86-type processors such as Intel's Pentium III chips into VLIW (very long instruction word) instructions that can be read by Crusoe's underlying hardware.

"Transmeta's new idea here was not to use silicon itself to solve the problem, but to use software to solve this problem," said Ditzel, a former chief architect at Bell Laboratories.

Two chips were unveiled: the TM5400, for lightweight notebook computers running the Microsoft Windows operating system, and the TM3120, a processor for Internet appliances running the Linux OS.

The TM3120 processor is priced at $US65 for the 333MHz version and $89 for the 400MHz version. Transmeta said in a statement it tried to price the chips economically enough for use in Linux-based Web pads that will be priced between $500 and $999.

The TM5400 will be offered in a range of performance levels from 500MHz to 700MHz and aimed at ultra-lightweight notebooks that will be priced between $1200 and $2500, the company said. The 500MHz version will list for $119, while the 700MHz version will list for $329.

The processors will be marketed for the mobile market and consume an average of 1 watt of power, which, according to Ditzel, will greatly enhance battery life. This is achieved by a new power management technology developed by Transmeta which the company calls LongRun.

LongRun allows Crusoe to "learn" about applications as it runs them and adjust its operating speed and voltage accordingly, Ditzel said. LongRun can make such adjustments hundreds of times per second, according to a statement provided by the company.

Transmeta began sampling Crusoe last year and expects to be shipping commercial products to manufacturers by mid-year. The company will sell manufacturers the chips, along with a range of software technologies to help them design mobile Internet devices based around Crusoe.

"Transmeta has all the technical pieces to enable computer manufacturers to very quickly bring entire products to market," Ditzel said. Those pieces include modified versions of a mobile version of the Linux operating system, he said.

The company has technology backing from IBM, which will provide Transmeta with access to some of its most advanced semiconductor technologies, Ditzel said. IBM has set up a team in California dedicated to working on Transmeta products, he said.

Transmeta now employs 200 people. Most are at the company's Santa Clara headquarters. Others are in Japan and Taiwan, where much of the PC manufacturing industry resides, Ditzel said. "We're not a small company anymore."

The name Crusoe comes from the famous fictional traveller Robinson Crusoe, who was washed up on an island after a shipwreck.

"We think it brings a name that denotes mobility," Ditzel said.

Transmeta clearly will find itself on a head-on collision course with Intel if it delivers on its promise of a low-power notebook chip that runs Windows applications. Power consumption has been the enemy of Intel and its rivals as they try to boost the power of their mobile chips.

Just this week Intel unveiled a new technology that lets its notebook chips work in different power modes depending on whether a user is mobile or plugged into an electrical outlet.

Transmeta will demonstrate a range of products using Crusoe at a press conference here this week. One of them is a "Web pad", a small form-factor device with a touch-screen keypad that Transmeta developed, which will be one of the technology components the company makes available to customers.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
