Reconfigurable Chaos-Based Microchips Offer Possible Solution to Moore’s Law

NCSU News (09/20/16) Tracey Peake

Nonlinear, multi-functional integrated circuits could lead to novel computer architectures that can do more with fewer transistors, according to researchers at North Carolina State University (NCSU). As the number of transistors on integrated circuits increases to keep up with processing demands, the semiconductor industry is seeking new ways to create computer chips without continually shrinking the size of individual transistors. The NCSU researchers utilized chaos theory to leverage a circuit’s nonlinearity and enable transistors to be programmed to perform different tasks. “In current processors you don’t utilize all the circuitry on the processor all the time, which is wasteful,” says NCSU researcher Behnam Kia. “Our design allows the circuit to be rapidly morphed and reconfigured to perform a desired digital function in each clock cycle.” Kia and NCSU professor William Ditto developed the design and fabrication of the integrated circuit chip, which is compatible with existing technology and utilizes the same processes and computer-aided design tools as existing computer chips. Ditto says the design is nearing commercial size, power, and ease of programming and could be of commercial relevance within a few months.
