Question

WHAT ARE THE MAIN FUNCTIONS OF CPU? EXPLAIN??​

Answer 1

Answer:

The CPU processes instructions it receives in the process of decoding data. In processing this data, the CPU performs four basic steps:

Fetch: Each instruction is stored in memory and has its own address. The processor takes this address number from the program counter, which is responsible for tracking which instructions the CPU should execute next.

Decode: All programs to be executed are translated to into Assembly instructions. Assembly code must be decoded into binary instructions, which are understandable to your CPU. This step is called decoding.

Execute: While executing instructions the CPU can do one of three things: Do calculations with its ALU, move data from one memory location to another, or jump to a different address.

Store: The CPU must give feedback after executing an instruction, and the output data is written to the memory.

A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer programby performing the basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions

The Four Primary Functions of the CPU

The CPU processes instructions it receives in the process of decoding data. In processing this data, the CPU performs four basic steps:

The CPU is the hardware responsible for applying operations to your data, such as comparing two numbers to see if they’re equal (and deciding on a course of action depending on whether they are) or doing math on some numbers. A program is a list of instructions for the CPU to follow in order, though some of the instructions could cause it to immediately jump somewhere else in the program, maybe depending on some logic operation (e.g., if this number is even, jump somewhere else, otherwise continue on to the next instruction).

The instructions also tell the program where in memory necessary data will be located. For example, if your program calculates the square root of a number, you’ll need to know where to find the number you want to take the square root of.
