ARM-Cortex-M3-cn

说明：  Cortex-M3是首款基于ARMv7-M架构的处理器，是专门为了在微控制器，汽车车身系统，工业控制系统和无线网络等对功耗和成本敏感的嵌入式应用领域实现高系统性能而设计的，它大大简化了可编程的复杂性，使ARM架构成为各种应用方案（即使是最简单的方案）的上佳选择。
(Cortex-M3 is the first based on ARMv7-M processor architecture, is designed for in microcontrollers, automotive body systems, industrial control systems and wireless networks such as power consumption and cost-sensitive embedded applications to achieve high system performance and design, it greatly simplifies the complexity of programmable, so that ARM architecture has become a wide range of applications programs (even the most simple program) a good choice.)
