LONDON – The chaos that results from non-linear mathematics could have a part to play in semiconductor logic, according to researchers drawn from universities in the United States and India, and a startup company called ChaoLogix.
The research team has demonstrated "chaotic" devices built in silicon and have presented their findings in Chaos, a journal published by the American Institute of Physics.
The research uses nonlinear relations to create a device that can generate all possible fundamental logic gate outputs. This forms the basis of the design of a dynamical computing device, a so-called chaogate, which can rapidly become any desired logic gate. The researchers and the startup indicate that the development could have particular significance for data security applications.
The example is given of a two-input, one output device that can be NOR, NAND, and XOR and its functionality is controlled in a VLSI design by control voltages through analog multiplexing circuitry. The authors have used non-linear dynamics to encode and manipulate inputs to produce a a wide variety of outputs. The set of desired outputs are then mapped to the system inputs and initial conditions and to their desired outputs.
The lead author is William Ditto, chair of the School of Biological and Health Systems Engineering, Arizona State University, who also serves as chief technology officer of ChaoLogix Inc. (Gainesville, Florida). Co-authors include Sudeshna Sinha of the Indian Institute of Science Education and Research at Chandhaghar, India and Krishnamurthy Murali of Anna University, Chennai, India.
As I understand the concept of entanglement, the selection of a possible common historical base within the computation could eliminate a very large amount of thereby discovered and thus unnecessary computational involvement.
Terry, an excellent elaboration but it's still very difficult to understand how entanglment could be used in the real world to process data at a faster rate. How can customization of functions dynamically be faster than having dedicated hardware lying in wait for data to be processed?
I agree. The timing and execution will have to be expertly executed. This technology reminds me of the cancer treatment that works on DNA structure, but is not able (at this time) to be administered to patients. I hope scientists and technology professionals will continue to work on both types of tech to find solutions that deliver significant results (and cures).
I was reminded of fuzzy logic when I read this article. Is there any family history connecting the chaosgates and fuzzy logic? I also remembered using and "programing" analog computers while in college, it was really fun back then with all the patchcords. I am wondering now the control for the gates works in this device, what drives it to change and what maintains its "state"?
This reminds me of the line by Jane Goodall that follows:
"There isn't a sharp line dividing humans from the rest of the animal kingdom. It's a very wuzzie line, and it's getting wuzzier all the time"
So how is "wuzzie" different from "fuzzy"?
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
