Basically in digital system there are two type of circuit: combinational logic circuit and sequential logic circuit. When the authors talk about combinational circuit, this circuit is that circuit of ...

A full adder is a combinational circuit that forms the arithmetic sum of three bits. It consists of three inputs and two outputs. The logic diagram as shown is a full adder implemented in ...

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 ...

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 ...

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 ...
