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 ...

Power consumption control in logic circuits, long a feature of forward looking papers from Japanese companies at ISSCC, hit the conference mainstream last week when Intel presented a paper on a 4GHz ...

The developing team at Arith-Matic a British computational hardware project and micro startup, have created a new 4-bit arithmetic unit, designed to be provided in kit form and “beautifully dissects ...

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 ...

When we are introduced to the internals of a microprocessor, it is most likely that we will be shown something like one of the first generation of 8-bit CPUs from the 1970s. There will be the familiar ...

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 Logic ...
