1 第1章 單晶片微電腦概論

2 1-1 電腦系統五大單元 Output Unit Display, Printer, speaker Memory Unit
功能: 儲存資料 & 程式 Input Unit Keyboard, mouse, card reader, scanner, microphone, camera Arithmetic Logic Unit 功能: 算術運算 - 加減乘除 邏輯運算 - AND, OR, XOR, NOT 條件判斷 - Control Unit 功能: 控制各單元 協調各單元

3 Memory Unit 儲存內容: 資料 & 程式 主記億單元:semiconductor memory 1. ROM
儲存內容: 資料 & 程式 主記億單元:semiconductor memory 1. ROM (1) Mask ROM (fabricated with data) (mask = 光罩) (2) PROM (Programmable ROM) (can only be written once) (3) EPROM (Erasable PROM) (Erased with UV) (4) EEPROM (Electrically erasable PROM) (byte- programmable) (5) Flash memory (A special type of EEPROM that is erased and programmed in large blocks) 2. RAM (1) DRAM – 以電容為儲存元件 (2) SRAM – 以flip flop為儲存元件 輔助記憶單元:magnetic disk, optical disk Capacity Speed 主記億單元 輔助記憶單元
