ARM-汇编指令集-PDF版

常用 ARM 指令集及汇编

ARM（Advanced RISC Machines）是微处理器行业的一家知名企业，该企业设计了

大量高性能、廉价、耗能低的 RISC 处理器、相关技术及软件。技术具有性能高、成本

低和能耗省的特点，适用于多种领域，比如嵌入控制、消费/教育类多媒体、DSP 和移

动式应用等。

ARM 将其技术授权给世界上许多著名的半导体、软件和 OEM 厂商，每个厂商得到的

都是独一无二的 ARM 相关技术及服务,利用这种合作关系，ARM 很快成为许多全球性 RISC

标准的缔造者。

目前，ARM内核的微处理器正在我国迅速普及和发展，许多朋友已经开始着手学习、

研究和利用这类芯片进行商品化设计，为了帮助广大朋友更快的学习和使用这种先进的

技术，广州周立功单片机发展有限公司(
