Harvard Team Makes Programmable Logic from Nanowires

9 February 2011-Transistors made from silicon-clad germanium nanowires-much smaller than traditional transistors-have for the first time been built into programmable “logic tiles,” say researchers at Harvard University. Such tiles, layered together, could be the foundation for miniature processors that could control microrobots or run implantable medical monitors. Professor Charles Lieber and his colleagues demonstrated silicon/germanium nanowire field-effect transistors (FETs) back …

Creating video that mimics human visual perception

Recent significant breakthroughs in core video processing techniques have nurtured video technology into one that looks aptly placed to contest the capabilities of the human visual system. For one, the last couple of decades have witnessed a phenomenal increase in the number of pixels accommodated by display systems, enabling the transition from standard-definition (SD) video to high-definition (HD) video. …

Microcontroller Tutorial

A Microcontroller is a small and low-cost computer built for the purpose of dealing with specific tasks, such as displaying information in a microwave LED or receiving information from a television’s remote control. Microcontrollers are mainly used in products that require a degree of control to be exerted by the user. Microcontroller v/s microprocessor Microprocessors are used to execute big …
