Quantum computer requires requires quantum arithmetic. The sophisticated design of a reversible arithmetic logic unit (reversible ALU) for quantum arithmetic has been investigated in this letter. We ...

Since arithmetic and logic operations within processing ICs are a crucial factors for speed, we developed a new approach to the ALU.

A computer is, at its core, just a bunch of transistors wired together. Once you have enough transistors on a board, though, one of the first layers of abstraction that arises is the Arithmetic ...

It is based on the Motorola MC14500 1-bit industrial controller, but since [David] changed the basic logic unit into an arithmetic-logic unit, he’s dubbing it the UE14500.

The S1-AU Mk1 is a beautifully crafted DIY hardware kit designed with 7400 series logic chips. It enables you to build a simple 4-bit arithmetic unit and manually perform binary operations.“ ...

At a bare minimum, a CPU is an instruction decoder and an arithmetic logic unit (ALU); the decoder reads instructions from memory and directs the ALU to perform appropriate arithmetic.
