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 ...

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 ...

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

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.

The CPU and memory work together to process instructions and run programs. There are different types of memory – volatile and non-volatile. The Arithmetic and Logic Unit (ALU) is where the CPU ...
