What is the main function of the arithmetic unit in a microcomputer?

The main function of the arithmetic unit in the microcomputer is to perform arithmetic operations and logical operations. The arithmetic unit consists of an arithmetic logic unit, an accumulator, a status register, a general-purpose register group, etc. The operation and type of operation of the arithmetic unit are determined by the controller.

The arithmetic unit consists of an arithmetic logic unit (ALU), an accumulator, a status register, a general purpose Register group, etc. The basic functions of the Arithmetic Logic Operation Unit (ALU) are the four arithmetic operations of addition, subtraction, multiplication, and division, logical operations such as AND, OR, NOT, and XOR, as well as operations such as shift and complement. When the computer is running, the operations and types of operations of the arithmetic units are determined by the controller. The data processed by the operator comes from the memory; the processed result data is usually sent back to the memory or temporarily stored in the operator. Together with the Control Unit, it forms the core part of the CPU.
