An arithmetic-logic unit (ALU) is part of a computer processor (CPU) that performs arithmetic and logic on the operands in computer s s instructions. In some processors, the ALU is divided into two units, an arithmetic unit (AU) and a logical unit (LU). Some processors may contain more than one AU - for example, one for fixed-point operation and one for floating point operations. (In personal computers floating point operations are sometimes performed by a floating point unit on a separate chip called a coprocessor number.)
Typically, the ALU has direct input and the output approach control processor, main memory (random access memory or RAM in a personal computer), and the input device / output. Inputs and outputs flow along an electronic path is called a bus. The inputs include a command word (sometimes called a command from the computer) contains an operation code (sometimes called a "code op"), one or more operands, and sometimes a code Format. Operation code tells the ALU what operation to perform and the operands used in the operation. (For example, two operands can be added together or reasonably comparable.) The format can be combined with the op code and say, for example, whether it is a fixed point or a floating-point instructions. The output includes a result which is placed in a storage register and settings that are active only have been done successfully.
(If it is not, some kind of state will be stored in a fixed place which is sometimes called the machine status.) In general, the ALU includes storage places for input operands, operands are added, the cumulative result (stored in a battery), and transfer results. The flow of bits and the operations performed on them in the subunits of the ALU is controlled by gated circuits. The gates of the circuit is controlled by a logic unit that uses a string of special algorithms, or code sequence for each activity. In the arithmetic unit, multiplication and division are performed by a variety of adding or subtracting and moving operations. There are several ways to represent negative numbers. In the logic unit, one of 16 possible logic operations can be carried out - such as comparing two operands and identifying where bits do not match.
The design of the ALU is obviously an important part of the processor and the new approach to accelerate the handling of orders continuously being developed.
