## Chapter Overview
[TOC]

### General Concepts
#### Basic microcomputer design
- clock synchronizes CPU operations 時鐘同步化CPU操作
- control unit (CU) coordinates sequence of execution steps
- ALU performs arithmetic and bitwise processing
#### Clock
- synchronizes all CPU and BUS operations
- machine (clock) cycle measures time of a single operation
- clock is used to trigger events
