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…

在看这一章之前,建议大家先去看一下snapshot的使用.可能有人会有疑问为什么要做Snapshot,hdfs不是自带了3个备份吗,这是个很大的误区,要知道hdfs的3个备份是用于防止网络传输中的失败或者别的异常情况导致数据块丢失或者不正确,它不能避免人为的删除数据导致的后果.它就想是给数据库做备份,尤其是做删除动作之前,不管是hbase还是hdfs,请经常做Snapshot,否则哪天手贱了... 直接进入主题吧,上代码. public void takeSnapshot(SnapshotDes…

Transmission Control Protocol, TCP是一种面向连接的.可靠的.基于字节流的传输层通信协议. 应用层向TCP层发送用于网间传输的.用8位字节表示的数据流,然后TCP把数据流分区成适当长度的报文段(通常受该计算机连接的网络的数据链路层的最大传输单元(MTU:Maximum Transmission Unit)的限制).之后TCP把结果包传给IP层,由它来通过网络将包传送给接收端实体的TCP层.TCP为了保证不发生丢包,就给每个包一个序号,同时序号也保证了传送到接收端实…
