Abstract: Adder is a very basic component in a central processing unit. The speed of compute becomes the most considerable condition for a designer. The carry lookahead adder is the highest speed ...

Generates the S signal through P ^ Co, where P is the Carry Propagate Signal (P = A ^ B) CMOS, TG PTL and Dynamic NMOS PTL implementations designed and tested. (TG PTL is a 3 input XOR, S = A ^ B ^ Co ...

We present the design and evaluation of a quantum carry-lookahead adder (QCLA) using measurement-based quantum computation (MBQC), called MBQCLA. QCLA was originally designed for an abstract, ...

A carry-look ahead adder improves speed by reducing the amount of time required to determine carry bits. It can be contrasted with the simpler, but usually slower, ripple-carry adder (RCA), for which ...

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 ...
