The sophisticated design of a reversible arithmetic logic unit (reversible ALU) for quantum arithmetic has ... von Neumann-Landauer limit of energy dissipated per irreversible bit operation. The ...

One of the more famous of these devices is the 74181, a cascadable 4-bit arithmetic logic unit, or ALU. An ALU is the heart of a microprocessor, performing its operations. The 74181 appeared in ...

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.“ ...

In this paper VHDL implementation of 8-bit Arithmetic Logic Unit (ALU) is presented. The design was implemented using VHDL Xilinx Synthesis tool ISE 13.1 and targeted for Spartan device.

An earlier logic chip used as a building block for CPUs. Bit slice processors used arithmetic logic units (ALUs) that typically came in 4-bit increments, although 1- and 2-bit devices were also made.

Once you have enough transistors on a board, though, one of the first layers of abstraction that arises is the Arithmetic Logic Unit. The ALU takes in two sets of data, performs a chosen math ...
