I loved the way you summarise it " to drive the vampire power into extinction". So if T-FET is one of the solutions to eliminate this vampire why is it not yet into production. What are the technical challenges that we have to face if we replace CMOS by TFET ?
Great Haloween Article!
Seriously though, I would love to see a chart showing the trade-off between the energy required to boot up a computer and sleeping. I'm assuming that computers that a hibernating computer is actually efficient up to a certain time, but don't know if it's 20 minutes or 8 hours?
It sad that our requirement of instant on has created such a phenomenon. If you look at the numbers from the set top boxes, it's horrible. I know that these numbers are a result the boxes remaining on all the time and just turning off outputs to look like they are off. For example,in setting up my GoogleTV box, I'm asked if I want lower power usage or faster power on time. How many people pick faster power on time without realizing the consequences?
In addition to efforts mentioned in the article, we need to work on some simple solutions also like fast boot for embedded OSes, and more extensive power management. These can be done today to reduce dramatically the power usage used during sleep for these devices.
it is quite surprising figure for me...10% power drainage in idle...i used to think that the power consumption in such conditions is negligible but i was mistaken. I will keep in mind the electricity bill the next time i do not shutdown my laptop. To what value will able to reduce this vampire power? And Happy Halloween..maybe in future we can allow our electronic items to draw some vampire power for this day only :-)
Nice way of putting it this way :-), everyone would be happy to make sincere effort to kill the vampire.
Referring to the another article by Colin "IBM, Euro researchers seek CMOS successor" posted on 27th, it looks like now EU also has got involed along with IBM & the universities and may be EU is trying to come out with some norms/regulations to keep the "Vampire" under control? Can we expect any regulations to comply with for the Europian market in near future?
Wish you a happy Halloween!
Better drain power than blood ;-)...but if electronic devices get to be more power efficient and cheaper we will just use more of them?!?...I already have 4 laptops, 3 TVs, 2PCs, VCR, PCR, 5 phones etc in one household...happy Halloween everybody! Kris
CMOS, FET, - Tunnel FET... what under-graduates have to learn nowadays! yish!
sounds great... though It'll take sometime because we're talking about all the foundries using this new silicon technology aren't we? well in the mean time I'll continue unplugging my equipments to take that 10% off from my electricity bill.
I hope that the lessons learned from Europe's Steep program can be translated unto American soil where the Vampire's power drains many more idle CPUs on a per capita basis. Taking the metaphor to the extreme vampires suck your juices while zombies just move around speechless. I don't wish that on anybody! Happy Halloween!
Vampire power is not like flower power, but rather is a force that is constantly draining your mobile devices batteries even when you are not using them. Hopefully, the European Union can once and for all eradicate this vampire force, which after all originated in Transylvania which is a part of Romania, a member of the E.U.
