Scientists are stacking processor cores on top of each other - China Led Stage Lights

That is the several billion $$ question, and there are several waysto do this. 1) turbo boost the top core for best single core performance, andthen have TONS of smaller cores throughout the rest of the chip. Soinstead of having architecture akin to what we are use to with 2-8traditional cores which can each do anything, we would seesomething more like the Cell processor with 1 'command' core,followed by a bunch of either specialized cores, or even morehomogeneous cores that are more similar to an ARM architecture. 2) You can have a fair amount of physical distance between layers,and still have an advantage over a flat chip for signal processing.Thermal pipes or vents could still be crammed between layers forheat dissipation.

Joytech22 mentioned the idea of changing the heatsink contact from the top only, to being on the top and edges. Iwould submit an idea of putting the pin-outs on the edges andhaving heat spreaders on what has traditionally been the top andbottom. 3) Engineers ultimately need lithography and design tools thatallow them to get away from 2D chip design. The real advantage to3D chips is not in layering cores on top of each other, but makingeach core a 3D structure so that the inputs and outputs ofindividual processing 'routes' are closer together, and then makingthe physical distance of these 'routes' shorter.

Less distance,means less resistance, means lower voltage, means less amperage,means less heat. These also mean less latency and faster processingtime for instructions (and also less material used). However, thisis still in the science fiction realm as the tools to do it are notreally available yet, but this is the direction we will have totake in time. 4) The material we are using for chips today (silicon) is not thebest at heat dispersal, it was merely readily available at thetime, and we have a whole eco system built around it which helpskeep the cost down. Moving to other materials (graphene,molybdenite, even diamond) will go a long way towards better heatdispersal. T8 Led Tube Light

Silicone is a heat insulator. Moving to something thatconducts heat without a large amount of electricity would allow formuch better cooling. Even more interesting is the idea of havingthe chip made out of a conductive material, and then insulating theroutes. IBM has already done this with a copper processor ~20 yearsago.

It was just a research project to see if it could be done, butwas not seriously pursued because it was not practical. Still, itis just one of many ideas of how to make 'cooler' chips that couldbe stacked. 5) Stacking everything in layers is not necessarily the bestdesign. In a 3D space where heat is of concern a better approachmay be more of a radial hub and spoke aproach, or constructing achip with a backplane and fins like we do in our computer with amotherboard and daughter cards (a backplane controller andconnector interface with specialty processors at right angles toit).

Imagine the control unit (with integrated northbridge andcache... because lets face it, the north-bridge is going todisappear soon) on the back-plane, and then having processing coresperpendicular to it, or radiating outwards from it. 6) moving away from electrical processors and moving towards lightbased processing. Very cool, less heat, less power, and superawesome (aka, I have no idea how it works ) anywho, sorry for rambling. This is something I have dreamed aboutsense I was a kid, and it is super exciting to see it start to comeinto reality! It will be very interesting to see what comes out ofthe market to solve these interesting space and heat issues.

Soexciting!

Consumer reports says apple's new ipad heats to 116 degrees runninggames - 6 Layer PCB

Consumer Reports, the consumer advocacy group that gained notorietyfor refusing to recommend Apple's iPhone 4 because of its externalantenna, has tested Apple's new iPad and found it can heat up to116 degrees when running graphic-intensive games [updated]. Update: The tests from Consumer Reports were quickly published on Tuesday afternoon, and the organization said its engineersrecorded temperatures as high as 116 degrees Fahrenheit whileplaying Epic's "Infinity Blade II." The iPad was standing up withApple's Smart Cover, the 4G LTE connection was not turned on, andthe tablet was plugged in while the game ran for 45 minutes. The highest unplugged temperature for the new iPad was found to be113 degrees Fahrenheit, while plugged in it reached 116 degrees.Those temperatures were 13 degrees and 12 degrees hotter,respectively, than identical tests conducted with the iPad 2. "During our tests, I held the new iPad in my hands. When it was atits hottest, it felt very warm but not especially uncomfortable ifheld for a brief period," author Donna L. 6 Layer PCB

Tapellini wrote. The testing also found that the iPad wouldn't recharge its batterywhile the game was running and it was plugged in. Instead, thebattery continued to drain, suggesting the power draw of the newA5X processor was too great for the iPad's USB connection toovercome during heavy use. Earlier Tuesday, Consumer Reports indicated its plans to publish its findings. In a "First Look Review" published last week , Consumer Reports said Apple's third-generation tablet was"shaping up as the best tablet yet." "The iPad's high-resolution display requires more power, and theefficiency of the A5X should help mitigate the battery drain itcauses," the group wrote last week. 6 Layer PCB

"We'll post results of ourbattery life tests soon." Of course, it's that larger battery, Retina display and morepowerful quad-core graphics processing that have led to a slightincrease in operating temperature on the new iPad, when compared tolast year's iPad 2. Apple issued a comment on the matter earlier Tuesday, stating that the new iPad operates"well within" its temperature specifications. The issue began to gain traction this week after an infrared testof the new iPad found it runs 10 degrees hotter , on average, than the iPad 2. The new iPad was measured at 92.5degrees Fahrenheit, while the iPad 2 measured 83 degreesFahrenheit. China Heavy Copper PCB

News Release June 7, 2012 For Information: Darren Allen Vermont NEA 802.224.2403 (office) 802.839.8618 (cell) MONTPELIER Vermont-NEA s Board of Directors recommends theelection of Treasurer Beth Pearce, who deserves a second full termafter ensuring the safety, stability and viability of Vermont spension funds since she was appointed to the job two years ago. Beth understands the relationship between sound fiscalstewardship and the economic well-being of working Vermonters, said Vermont-NEA President Martha Allen. At a time whenanti-worker rhetoric is heating up all over America, it is acomfort to have someone like Beth watching over our state sfinances. Gov. Peter Shumlin appointed Pearce to take the job after tappingthen-Treasurer Jeb Spaulding as his Secretary of Administration.While this will be Pearce s first electoral campaign, she had beena long-time deputy to Spaulding and was instrumental in ensuringthe office worked well.

It is not an exaggeration to say that Beth was integral inachieving the historic teacher pension reform deal we,then-Treasurer Spaulding and then-Gov. James Douglas reached in2009, Allen said. Her steadfast attention to detail and keenunderstanding of pensions certainly guided everyone towardagreement. In that 2009 agreement, the Vermont State Teachers RetirementSystem was the only one in the nation to address the needs oftaxpayers, retirees and current teachers: teachers agreed to paymillions more; they agreed to work a little longer; and theyobtained health coverage in retirement for their spouses.

Vermont-NEA does not routinely make candidate recommendations thisearly in the process. However, because of the importance ofmaintaining and strengthening the state s pension plans toVermont-NEA members, the union said it wanted to express itssupport now. Working people everywhere, even in Vermont, are under attack,particularly those who do the work of the public, Allen said. Beth is a champion of working men and women, and she representsthe best chance that pensions built up and paid for by workers overthe decades will remain intact. The union invited all three candidates currently running forTreasurer to address the board of directors; only Pearce acceptedthe invitation. Dry Herb Vaporizers
