How CPU Architecture Works?

The CPU follows a fetch-decode-execute cycle:

1. Fetch: Retrieves instructions from memory.
2. Decode: Interprets what the instruction means.
3. Execute: Performs the task using internal components.

These instructions are written in machine code, a binary language specific to the CPU’s
architecture. Programs written in high-level languages like Python or Java are compiled into
machine code that the CPU can understand.

Communication with Other Components

The CPU communicates with other parts of the system via buses and chipsets:

Bus Type Function

Data Bus Transfers actual data

Address Bus Specifies memory locations

Control Bus Sends control signals (e.g., read/write)

It also relies on:
● RAM: Temporary storage for active data
● Cache: Fast internal memory for frequent tasks
● Chipset: Manages connections to storage, USB, and other peripherals
