AN2548 -- 使用 STM32F101xx 和 STM32F103xx 的 DMA 控制器 DMA控制器 DMA是AMBA的先进高性能总线(AHB)上的设备,它有2个AHB端口: 一个是从端口,用于配置DMA,另一个是主端口,使得DMA可以在不同的从设备之间传输数据. DMA的作用是在没有Cortex-M3核心的干预下,在后台完成数据传输. 在传输数据的过程中,主处理器可以执行其它任务,只有在整个数据块传输结束后, 需要处理这些数据时才会中断主处理器的操作. 它可以在对系统性能产生较小影响…

====================== 我自己的理解 ========================== 一:  DTO  我自己的理解,就是 比如你有一个类,跟数据库的table表结构一模一样,主键外键什么的都有,但是这个 model类,你返回数据到 UI层的时候,有些数据是不用的,你就得自己new一个新类出来,新的类从旧的类里面拿值,然后给别人用的就是新的类别,有点类似于我们做接口给android手机用一样的,数据库的类和接口用的类,很相似,但是东西少了的很多,这个新的类(缺胳膊断腿…

要在 .NET Framework 中实现分布式应用程序.客户端应用程序需要显示一个窗体,该窗体要求对 ASP.NET Web Service 进行多个调用以满足单个用户请求.基于性能方面的考虑,我们发现,进行多个调用会降低应用程序性能.为了提高性能,需要通过对 Web Service 进行一次调用就能检索到用户请求所需的所有数据. 背景信息 注意:以下是在 .NET 中使用类型化 DataSet 实现 Data Transfer Object 中所描述的同一个示例应用程序. 下面是一个简化的…
正在设计一个分布式应用程序,为了满足单个客户端请求,您发现自己对一个远程接口发出了多个调用,而这些调用所增加的响应时间超出了可接受的程度. 影响因素 在与远程对象通信时,请考虑下列需要权衡的因素: 远程调用(那些必须跨越网络的调用)速度缓慢.虽然许多远程调用框架可以隐藏进行远程调用的复杂性,但是它们不能消除发生通信所需的步骤.例如,必须先找到 远程对象位置,而且建立与远程计算机的连接,然后才能将数据串行化为字节流,然后可能进行加密,最后才能将其传输到远程计算机. 在 考虑网络性能时,必须同时考虑…

数据转换(Data transfer) 方差分析的前提是方差齐性,可以使用transfer改变方差使得方差变齐.不正态和outlier. Logarithmic transformation使方差聚合.取平方使方差离散.二项分布使用反正弦转换. 注意:远远偏离0.5则不管用,在0.5附近则转不转都很正态. 常见概率分布对应的处理方法: 虽然存在一套常见概率分布的克服方法,但是仍有不能克服的问题,比如1.outlier2.双峰3.长尾分布.于是又提出Box-Cox方法,现有R package(MA…
