The ALU is a basic building block of the central processing unit (CPU) of a computer, even the simplest microcontrollers contain one for purposes such as timing. In some microprocessor architectures, the ALU is divided into the arithmetic unit (AU) and the logic unit (LU). ARITHMETIC & LOGIC UNITS An arithmetic logic unit (ALU) is a combinational digital electronic circuit that performs arithmetic and bitwise operations on integer binary numbers. Depending on how the ALU is designed, it can make the CPU more powerful, but it also consumes more energy and creates more heat. The ALU serves as the foundation of central processing units (CPUs), graphics processing units (GPUs), and floating point units (FPUs).A simple ALU has three data buses: two single-bit operands (A and B) that result in one output (Y). In some microprocessor architectures, the ALU is divided into the arithmetic unit (AU) and the logic unit (LU). Modern CPUs contain very powerful and complex ALUs. Multiplication and subtraction can also be done by repetitive additions and subtractions respectively. Therefore, there must be a balance between how powerful and complex the ALU is and how expensive the whole unit becomes. Our ALU should be able to perform functions: logical and function logical or function arithmetic add function arithmetic subtract function arithmetic slt (set-less-then) function logical nor function ALU control lines define a function to be performed on A and B. It normally executes logic and arithmetic operations such as addition, subtraction, multiplication, division, etc. b It performs both bitwise and mathematical operations on binary numbers and is the last component to perform calculations in the processor. It is often referred to as the “engine” of the CPU because it allows the computer to perform mathematical calculations, such as addition, subtraction, and multiplication. Pour augmenter leurs performances, elles sont le plus souvent pipelinées. As the metaphorical brain of a computer, an arithmetic logic unit (ALU) performs all computational and comparison operations. An ALU can be designed by engineers to calculate many different operations. a , on construit les quatre signaux 4-13. The ALU is a fundamental building block of the central processing unit of a computer, and even the simplest microprocessor contains one for purposes such as maintaining timers. Les UAL élémentaires calculent sur des nombres entiers, et peuvent effectuer les opérations communes, que l'on peut séparer en quatre groupes : Certaines UAL sont spécialisées dans la manipulation des nombres à virgule flottante, en simple ou double précision (on parle d'unité de calcul en virgule flottante (UVF, en anglais floating-point unit, FPU) ou dans les calculs vectoriels. , The arithmetic, logic, and shift circuits can be combined into one ALU with common selection variables. Le second multiplexeur agit de la même façon avec les deux bits de poids fort de A et B : Le schéma des multiplexeurs 4 vers 1 ci-dessus est construit à base de circuits intégrés TTL tout à fait standard, dont les références sont affichées. The ALU also has three further control signals, which can be decoded to map to the 8 individual functions required of the ALU.
