Adders are one of the widely used digital components in digital integrated circuit design. In this paper, various adder structures can be used to execute addition such as serial and parallel ...

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 ...

Would you consider this to be doing math the old-fashioned way? Instead of going with silicon-based switching (ie: transistors) this 4-bit adder uses mechanical relays. We like it for its mess of ...

Increment and decrement. They sound like simple functions. But even the simplest functions can get quite complex in a microprocessor design. Ken Shirriff has written up a great blog post about his ...
