Detailed explanation-1: -The ALU performs arithmetic operations, logic operations, and related operations, according to the program instructions. The control unit controls all CPU operations, including ALU operations, the movement of data within the CPU, and the exchange of data and control signals across external interfaces (system bus).
Detailed explanation-2: -The arithmetic logic unit (ALU) performs the arithmetic and logical functions that are the work of the computer. The A and B registers hold the input data, and the accumulator receives the result of the operation. The instruction register contains the instruction that the ALU is to perform.
Detailed explanation-3: -function in digital computer The ALU performs simple addition, subtraction, multiplication, division, and logic operations, such as OR and AND. The memory stores the program’s instructions and data. The control unit fetches data and instructions from memory and… …
Detailed explanation-4: -What is an arithmetic-logic unit (ALU)? An arithmetic-logic unit is the part of a central processing unit that carries out arithmetic and logic operations on the operands in computer instruction words.
Detailed explanation-5: -CPU consists of Arithmetic Logic Unit (ALU) and Control Unit (CU). In addition, CPU also has a set of registers which are temporary storage areas for holding data, and instructions. ALU performs the arithmetic and logic operations on the data that is made available to it.
