Cortex-M 系列针对成本和功耗敏感的MCU 和终端应用（如智能测量、人机接口设备、汽车和工业控制系统、大型家用电器、消费性产品和医疗器械）的混合信号设备进行过优化。

.比较Cortex-M 处理器Cortex-M 系列是适用于具有不同的成本、功耗和性能的一系列易于使用的兼容嵌入式设备（如微控制器（MCU ））的理想解决方案。

每个处理器都针对十分广泛的嵌入式应用范围提供最佳权衡取舍。

关于Cortex-M4与Cortex-M3的区别，：M4不是用来取代M3的，它只是多了浮点运算功能。

软件工程导论(第7章)

测试的正确定义：“为了发现程序中的错误而执行程序的过程。”
7.2.2 软件测试准则
1）所有测试都应该能追溯到用户需求；
2）应该远在测试前就制定出测试计划；
3）把Pareto原理应用到软件测试中；Pareto原理说明测试发现的错误中的80%很可能是由程序中20%的模块造成的。
4）应该从“小规模”测试开始，并逐步进行“大规模”测试；
USER32.DLL； GDI32.DLL； KERNEL32.DLL。
Windows消息机制：
1）基于消息的事件驱动消息可以是由硬件发来的（存于系统队列）,
也可以由Windows系统和应用程序发来（存于程序队列中）；
每一个Windows程序在不停的捕捉各种消息, 并进行处理；
每个窗口都必须有一个窗口函数，来负责消息的判断与处理。
3）重要的执行路径由于不可能进行穷尽测试，因此选择测试
路径是非常关键的。 4）出错处理通路 5）边界条件
7.3.2 代码审查
审查小组： 1）组长； 2）程序的设计者； 3）程序的编写者； 4）程序的测试者。
7.3.3 计算机测试
由于软件模块不是一个独立的系统，不能独立运行，要依靠其他模块调用，或需要调用其他模块。
1.模块测试模块测试又称单元测试，它把每个模块作为
单独的实体来测试。 2.子系统测试
子系统测试是把经过单元测试的模块放在一起形成一个子系统来测试。
3.系统测试系统测试是把经过测试的子系统装配成一个完
整的系统来测试。 4.验收测试
验收测试把软件系统作为单一的实体进行测试（利用用户的实际数据测试）。 5.平行运行
如PL/1、PASCAL、C、ADA等 3）专用语言如APL、BLISS、FORTH、LISP、PROLOG等
