Conclusions: Arithmetic Logic Unit (ALU) for the Programmable Logic Device (RPLD) has been presented in this letter in a reversible way. The reversible version ALU aims at eliminating the energy ...

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

Starting with a guide on building logic gates from transistors it will eventually cover the arithmetic logic unit, adders, memory, clocks, and everything else that is needed for the complete CPU ...

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 ...

• Arithmetic logic unit: Processes all arithmetic operations. Sometimes this unit is divided into subunits, one to handle all integer add and subtract instructions, and another for the ...

An arithmetic unit which also performs bitwise logical operations is commonly referred to as an ALU (Arithmetic and Logic Unit). The S1-AU Mk1 is a beautifully crafted DIY hardware kit designed ...

It comprises an arithmetic-logic unit to carry out calculations, main memory to temporarily store data for processing, and a control unit to control the transfer of data between memory, input and ...

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 Arithmetic and Logic Unit (ALU) is where the CPU performs the arithmetic and logic operations. Data is passed to the ALU to allow the required calculations to be carried out.
