arm指令集(1) ARM跳轉指令可以從當前指令向前或向后的32MB地址空間跳轉。這類跳轉指令有以下4種。 （1）B 跳4專指令 B〔條件） （地址） B指令屬于ARM指令集，是最簡單的分支指令。一旦遇到一個B指令，ARM處理器將立即跳轉到給定的地址，從那里繼續執行。注意：存儲在分支指令中的實際值是相對當前R15的值的一個偏移量，而不是一個絕對地址。它的值由匯編器來計算，是24位有符號數，左移兩位后有符號擴展為32位，表示的有效偏移位為26位（＋／－ 32 MB）。 ?。?）BL 帶返回的跳轉指令 BI，〔條件） （地址） BL指令也屬于ARM指令集，是另一個分支指令。就在分支之前，在寄存器R14中裝載上R15的內容，因此可以重新裝載R14到R15中來返回到這個分支之后的那個指令處執行，它是子例程的一個基本但強力的實現。 （3）BLX 帶返回和狀態切換的跳轉指令 BLX ＜地址＞ BLX指令有兩種格式，第1種格式的BLX指令記作BLX（1）。BLX（1）從ARM指令集跳轉到指令中指定的目標地址，并將程序狀態切換到Thumb狀態，該指令同時將PC寄存器的內容復制到LR寄存器中。 BLX（1）指令屬于無條件執行的指令。 第2種格式的BLX指令記作BLX（2）。BLX（2）指令從ARM指令集跳轉到指令中指定的目標地址，目標地址的指令可以是ARM指令，也可以是Thumb指令。目標地址放在指令中的寄存器＜dest＞中，該地址的bit［0］值為0，目標地址處的指令類型由CPSR中的T位決定。該指令同時將PC寄存器的內容復制到LR寄存器中。 ?。?）BX 帶狀態切換的跳轉指令 BX（條件） （dest） BX指令跳轉到指令中指定的目標地址，目標地址處的指令可以是ARM指令，也可以是Thumb指令。目標地址值為指令的值和0xFl·FFFFFF做“與”操作的結果，目標地址處的指令類型由寄存器決定。

2.1.1 I/O接口基本概念1.為什么要引入接口微機和I/O設備的信息類型和格式可能不一樣。微機和I/O設備信號傳輸處理的速度可能不匹配。不用接口， I/O直接接CPU，隨著外設增加，會大大降低CPU的效率。I/O直接接CPU，會使外設硬件結構過于依賴CPU，對外設本身發展不利。2.接口的概念 定義：接口是CPU與“外部世界”的連接電路，負責“中轉”各種信息。 分類：存儲器接口和I/O接口。 位置：介于系統總線與外部設備之間。3.I/O接口與I/O設備不同I/O設備對應I/O接口不同。I/O接口受CPU控制，I/O設備受I/O接口控制。為增加通用性，I/O接口電路一般均具有可編程功能。微機的應用離不開外部設備接口的設計、選用和連接。2.1.2、I/O接口功能 數據緩沖功能：通過寄存器或鎖存器實現。 存放數據的寄存器或鎖存器稱之為數據口。 接受和執行CPU命令功能： 存放CPU命令代碼的寄存器稱之為命令口， 存放執行狀態信息的寄存器稱之為狀態口。 設備選擇功能：CPU通過地址譯碼選擇不同外設。 即CPU通過地址譯碼選擇不同I/O接口和I/O接口中連接的不同的設備。 信號轉換功能：協調總線信號與I/O設備信號。 轉換包括信號的邏輯關系、時序配合和電平轉換。 可編程功能：增加接口的靈活性和智能性。

很多不同的廠家生產各種型號的計算機，它們運行完全不同的操作系統，但TCP.IP協議族允許它們互相進行通信。這一點很讓人感到吃驚，因為它的作用已遠遠超出了起初的設想。T C P / I P起源于6 0年代末美國政府資助的一個分組交換網絡研究項目，到9 0年代已發展成為計算機之間最常應用的組網形式。它是一個真正的開放系統，因為協議族的定義及其多種實現可以不用花錢或花很少的錢就可以公開地得到。它成為被稱作“全球互聯網”或“因特網(Internet)”的基礎，該廣域網（WA N）已包含超過1 0 0萬臺遍布世界各地的計算機。本章主要對T C P / I P協議族進行概述，其目的是為本書其余章節提供充分的背景知識。 TCP.IP協議 縮略語 ACK
