Caltech scientists have created a fully reusable enzyme-free DNA computing system—unlocking new possibilities for autonomous ...

VHDL is all about creating logic. As a descriptive language, all the HDL languages bring something unique to programming – making true parallel logic circuit. As we take baby steps into VHDL, we will ...

The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

Researchers at the University of Rochester and the Friedrich-Alexander-Universität Erlangen-Nürnberg have created the fastest logic gates ever. If the process is ever brought to market, the ...

As Moore's Law begins to slow, the search is on for new ways to keep the exponential rise in processing speeds going. New research suggests that an exotic approach known as "lightwave electronics" ...

The digital world offers many advantages over its analog relatives, the use of boolean logic among them. Some of the functions, like NOT, OR, and AND are fairly straightforward and line up nicely with ...
