When Mobile Devices, laptops, and notebook Pcs were becoming common, A Processor called Crusoe was released which draws 1-watt power during normal usage on January 19th, 2000, Transmeta let the world in on its secret.
The processor family is aimed at Internet / mobile devices, and a goal of production was to make it “Internet compatible.” To Transmeta, that meant that not only did Crusoe have to support x86 instructions, run a standard OS, and run a browser, but it also had to be able to support plug-ins for ShockWave, Flash, or Java.
Besides being lighter, the Crusoe lasts longer than other processors.
With the flexibility that Crusoe brings to the laptop industry, manufacturers can keep the weight of a laptop under 4 lbs., and increase screen size, or add a second or even third drive. Or, they can dramatically reduce both weight and thickness. Or any combination of the above.
With a high-performance 128-bit VLIW (Very Long Instruction Word) hardware engine, and a software-based architecture, Crusoe requires fewer transistors. Since all transistors burn power, having fewer of them means Crusoe requires less power to do the same amount of work.
Secondly, Crusoe uses power wisely. Instead of running every application at the processor’s top speed, Crusoe’s unique ’smart processor’ architecture and LongRun® Power Management technology, look at the application, see where they can economize, and make the necessary adjustments — all in a few microseconds — to determine exactly how much performance the application demands.
In addition, the longer you run an application, the more Crusoe improves the application’s performance because it’s always learning. The result is that, with Crusoe, you always get the optimum performance, no more or less, and the maximum battery life.
Due to the fact that the Crusoe uses fewer transistors and manages power more efficiently, it can run at a much cooler temperature than other processors. Crusoe has a fundamentally different architecture, designed from the ground up to run cooler.
Intel, AMD or Transmeta – abc News(2017)
Crusoe-based machines can run all the software written for Intel’s Pentium processors, but Crusoe is actually a totally different animal.
Intel compatibility is key to Crusoe’s success because Intel-compatible machines have more than 90% of the home PC market. (Motorola’s PowerPC chips are at the heart of Apple’s Mac, which has been hovering between a 3 and 5 percent market share.)
Transmeta has already forced its much bigger competitors, Intel and AMD, to veer away from their fixation on ever-faster — which means ever-hotter — chips to try to find something that won’t conk out on you during a marathon computer session.
Carl Howe, research director at Forrester Research, says Transmeta is hitting Intel where it’s weak — targeting an expanding market for tiny laptops, Internet appliances, and other portable devices.
“The key idea is not just thinking about 12-hour laptops, thinking about 18-24 hour laptops. It’ll change the way that people think about their computers,” he said.
Transmeta’s chip has wowed industry experts with its successful battery-life savings but has also come under fire for being slow.
Testing the new Sony machine, PC World Labs found a 19 percent drop in performance on standard benchmarks from the previous edition of the PictureBook, which used Intel microprocessors.
Revving Up Competition AMD and Intel have both developed chips with speed-ratcheting technology similar to Transmeta’s. AMD’s PowerNow technology speeds the chip up and down in increments of 50 mhz, dynamically based on application demand, to save power. Intel’s SpeedStep knocks a 600 mhz chip down one step to 500 mhz when a laptop is unplugged.
But Transmeta’s chip also peaks at a lower wattage than Intel and AMD chips, saving more power. Intel has a low-power chip in the works and says the average wattage of an existing Mobile Pentium III chip is in the same range as the Crusoe.
Battery-draining wattage is a necessary evil with complex chips, Transmeta’s director of worldwide marketing Brian Hearst said. As a chip adds transistors to become faster and more powerful, those circuits suck up more electricity, he said.
Crusoe manages to use less energy by moving some functions of Intel and AMD chips into software, and building an entirely new processor architecture that uses fewer transistors, he said.
Crusoe Processor is really good small size, Low power consumption an can provide a very good battery life but the processing becomes slow. Slow is not going to work! people want things to happen faster than current. Intel is leading most of the market, the collaboration of Intel and Transmeta technology can be something.
