First computer made of tiny carbon nanotubes is unveiled

First computer made of tiny carbon nanotubes is unveiled | Technoscience and the Future | Scoop.it

The miniaturization of electronic devices has been the principal driving force behind the semiconductor industry, and has brought about major improvements in computational power and energy efficiency. Although advances with silicon-based electronics continue to be made, alternative technologies are being explored. Digital circuits based on transistors fabricated from carbon nanotubes (CNTs) have the potential to outperform silicon by improving the energy–delay product, a metric of energy efficiency, by more than an order of magnitude. Hence, CNTs are an exciting complement to existing semiconductor technologies.

 

Owing to substantial fundamental imperfections inherent in CNTs, however, only very basic circuit blocks have been demonstrated. Scientists from Stanford recently show how these imperfections can be overcome, and demonstrate the first computer built entirely using CNT-based transistors. The CNT computer runs an operating system that is capable of multitasking: as a demonstration, we perform counting and integer-sorting simultaneously. In addition, we implement 20 different instructions from the commercial MIPS instruction set to demonstrate the generality of our CNT computer. This experimental demonstration is the most complex carbon-based electronic system yet realized. It is a considerable advance because CNTs are prominent among a variety of emerging technologies that are being considered for the next generation of highly energy-efficient electronic systems.

The Electronic Brain? Your Mind Vs. a Computer

The Electronic Brain? Your Mind Vs. a Computer | Technoscience and the Future | Scoop.it

According to Chris Chatham at Developing Intelligence, the brain-computer metaphor has lead to a lot of over-simplification in our thinking about our thinking. "An unfortunate legacy is the tendency to seek out modularity in the brain... the idea that computers require memory has lead some to seek for the 'memory area,' when in fact these distinctions are far more messy." We're now learning that regions cannot be associated with a singular function (i.e. the frontal cortex as "the place where personality occurs").

The brain is not a storage dump, and consciousness is not a place. Synapses are also far more complex than electrical circuits. Neither processing speed nor short term memory capacity are fixed, whereas RAM is.
