Linux 是一个源码开放的操作系统，无论是普通用户还是企业用户都可以编写自己的内核代码，再加上对标准内核的裁剪从而制作出适合自己的操作系统。目前有很多中低端用户使用的网络设备的操作系统是从标准 Linux 改进而来的，这也说明了有越来越多的人正在加入到 Linux 内核开发团体中。 一个或多个内核模块的实现并不能满足一般 Linux 系统软件的需要，因为内核的局限性太大，如不能在终端上打印，不能做大延时的处理等等。当我们需要做这些的时候，就需要将在内核态采集到的数据传送到用户态的一个或多个进程中进行处理。这样，内核态与用户空间进程通信的方法就显得尤为重要。在 Linux 的内核发行版本中没有对该类通信方法的详细介绍，也没有其他文章对此进行总结，所以本文将列举几种内核态与用户态进程通信的方法并详细分析它们的实现和适用环境。-Linux is an open-source operating system, both ordinary users or enterprises, users can prepare their core code, coupled with the standard kernel cutting thereby making up their own operating system. There are a lot of low-end users of the network equipment from the standard operating system Linux is improving from the This also shows that the more and more people are added to the Linux kernel development groups. One or more modules and the realization of general Linux can not satisfy the needs of system software, because the core is too restrictive, such as the terminal can print, can not handle the bigger Delay etc..

要求上传五份源代码, 这是重量级的, 苹果达尔文服务器源代码, RTSP, RTP/RTCP等等, 其中RTSP解析, RTP/RTCP接收发送等等高效源码-request upload five source code, which is the heavyweight, Apple Darwin server source code, RTSP, RTP/RTCP, etc., analytic RTSP, RTP/RTCP receive this efficient source, etc.

PID控制仿真程序 假设一个控制系统：10kg的水，使用最大1kW的电阻丝加热，简化计算，假设焦耳和卡的转化单位为1，而不是4.2加热效率为 Watt [瓦],散热效率为5*T [瓦]设定目标温度为60度， 则100000秒内的温度变化曲线是如何的？-PID control simulation program assumes that a control system: 10kg of water, using hot-filament maximum 1kW resistor to simplify the calculation, assuming the conversion of Joule and card unit of one, instead of 4.2 for heating efficiency Watt [W], thermal efficiency of 5* T [W] set a target temperature of 60 degrees, then the 100000 sec the temperature curve is how?
