[Phillip] wanted to play with the C preprocessor. He decided to do that by creating a 4 bit full adder. We know this is pretty useless in everyday life, but it was a great learning experience. The ...

As a powerful material, DNA presents great advantages in the fabrication of molecular devices and higher-order logic circuits. Herein, by making use of the hybridization and displacement of DNA ...

You have a limited amount of logic left in a CPLD on your board. You would like to add a 32 bit ripple carry adder. How many gates are used in a 32 ripple carry adder? The 32 ripple carry adder is ...

Addition forms the basic structure for many processing operations like counting, multiplication, filtering etc. Adder circuits that add two binary numbers are of great interest for many designers. The ...

Adder logic cell is basically an important part of adder sub-system and is well known by the designers so many researchers are still working in this field for speeding up the circuit process along ...

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 ...

In Part 1 of this two-part binary coded decimal (BCD) extravaganza, we introduced a bunch of bodacious concepts, including the binary (base-2) number system, binary logic, binary computers, and bits, ...
