# CPU

* 프로그램의 연산을 처리하고 시스템을 제어하는 컴퓨터의 두뇌라 할 수 있다.
* 프로세스의 코드를 불러오고, 실행하고, 결과를 저장하는 일련의 모든 과정이 CPU에서 일어난다.
* CPU는 산술/논리 연산을 처리하는 산술논리장치(Arithmetic Logic Unit, ALU)와 CPU를 제어하는 제어장치(Control Unit), CPU에 필요한 데이터를 저장하는 레지스터(Register) 등으로 구성된다.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://krjaeh0.gitbook.io/j-log/programming/cs_basics/architecture/cpu.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
