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 ...

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 ...

The core of every microprocessor and digital signal processor is its data path. The heart of data-path and addressing units in turn are arithmetic units which include adders. Parallel-prefix adders ...

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 ...
