Booting an Intel Architecture System, Part I: Early Initialization

By Pete Dice, December 26, 2011 The boot sequence today is far more complex than it was even a decade ago. Here’s a detailed, low-level, step-by-step walkthrough of the boot up. Taking a lot of little steps along a path is a good analogy for understanding boot flow in Intel Architecture-based systems. The minimum firmware requirements for making a system …

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 …
