3-D Computer Processor


Scientist at University of Rochesterb have developed a new generation of Computer Processors. These processors are based on3-Dimensional Circuits in contrary to 2-Dimensional Circuits of today.This can be said as the next major advance in computer processors technology. The latest 3-D processor is running at 1.4 gigahertz in the labs of University.
PAST ATTEMPTS VS LATEST RESEARCH

In the past attempts of making 3-D chips, scientist were just making a stack of regular processors. But at University of Rochesterb it was designed and built specifically to optimize all key processing functions vertically, through multiple layers of processors, the same way ordinary chips optimize functions horizontally.

This design means that every tasks such as SynchronicityPower Distribution, and Long-Distance Signaling are all fully functioning in three dimensions for the first time.

EBY FRIEDMAN: THE MAN BEHIND 3-D CHIPS

Eby Friedman and his students has designed this chip, which uses many of the tricks of regular processors, but also accounts for different impedances that might occur from chip to chip, different operating speeds, and different power requirements. According to Eby Friedman, Professor of Electrical and Computer Engineering at Rochester and faculty director of the pro of the processor says:- “I call it a cube now, because it’s not just a chip anymore. This is the way computing is going to have to be done in the future. When the chips are flush against each other, they can do things you could never do with a regular 2D chip”

TODAYS INTEGRATED CHIPS AND PROBLEMS

The problem with today’s technology of integrated circuits is that, beyond a limit it is impossible to pack more chips next to each other which limits the capabilities of future processors. So number of integrated circuit designers anticipate someday expanding into the third dimension, stacking transistors on top of each other.

IMPORTANCE

Vertical Expansion of chips has lots of technical difficulties and the only solution to this is todesign a 3-D chip where all the layers interact like a single system. According to Friedman: Getting all three levels of the 3-D chip to act in harmony is like trying to devise a traffic control system for the entire United States-and then layering two more United States above the first and somehow getting every bit of traffic from any point on any level to its destination on any other level-while simultaneously coordinating the traffic of millions of other drivers.
Now if we replace the two United States layers to something more complicated like China and India where the driving laws and roads are quite different, and the complexity and challenge of designing a single control system to work in any chip begins to become apparent.

The 3-D Chip is essentially an entire circuit board folded up into a tiny package. With this technology the chips inside something like an iPod could be compacted to a tenth their current size with ten times the speed.

  1. Hiya, I’m really glad I have found this information. Nowadays bloggers publish just about gossips and net and this is really annoying. A good blog with interesting content, that’s what I need. Thank you for keeping this web-site, I’ll be visiting it. Do you do newsletters? Cant find it.

  2. Thanks for the tips you have contributed here. Another thing I would like to express is that computer memory demands generally rise along with other innovations in the engineering. For instance, if new generations of cpus are made in the market, there’s usually a corresponding increase in the type calls for of both pc memory and also hard drive room. This is because the application operated by these cpus will inevitably surge in power to leverage the new know-how.

  3. It’s a shame you don’t have a donate button! I’d definitely donate to this brilliant blog! I suppose for now i’ll settle for bookmarking and adding your RSS feed to my Google account. I look forward to fresh updates and will talk about this blog with my Facebook group. Chat soon!

  4. I absolutely love your blog and find almost all of your post’s to be precisely what I’m looking for. Would you offer guest writers to write content in your case? I wouldn’t mind composing a post or elaborating on some of the subjects you write regarding here. Again, awesome site!

  5. I have seen that charges for internet degree specialists tend to be an incredible value. For example a full Bachelors Degree in Communication in the University of Phoenix Online consists of 60 credits from $515/credit or $30,900. Also American Intercontinental University Online makes available Bachelors of Business Administration with a whole program requirement of 180 units and a tuition fee of $30,560. Online studying has made getting the degree far more easy because you may earn your current degree through the comfort of your home and when you finish working. Thanks for all tips I have really learned from your blog.
