A user
A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running computation, block while waiting for an event, or read files from the file system. Unlike kernel drivers, a user-space device driver can use other device drivers--that is, access the network, talk to a serial port, get interactive input from the user, pop up GUI windows, or read from disks. User-space drivers implemented using FUSD can be much easier to debug it is impossible for them to crash the machine, are easily traceable using tools such as gdb, and can be killed and restarted without rebooting even if they become corrupted. FUSD drivers don t have to be in C--Perl, Python, or any other language that knows how to read from and write to a file descriptor can work with FUSD. User-space drivers can be swapped out, whereas kernel drivers lock physical memory.-A user-space device driver can do many of the things that kernel drivers can t, such as perform a long-running comput

NUTTX操作系统源码
Nuttx 是一个实时嵌入式操作系统（Embedded RTOS），它很小巧，在微控制器环境中使用。Nuttx完全可扩展，可从从小型（8位）至中型嵌入式（32位）系统。它的设计目的还在于完全符合POSIX标准，完全实时，并完全开放。

现在有很多的相机类型，和一些鱼
现在有很多相机类型，有的鱼眼相机照完的图片会发生畸变，为此，我们要进行鱼眼图片校正。本程序正是针对鱼眼图象的校正程序，里面有详细的注释说明相信只要是有一定的基础的人都能看懂。不过，还有差值部分没做完哪，有待完善。-Now have a lot of camera types, and some fish-eye camera images will be finished according to distortion, to that end, we have to carry out fish-eye image correction. This procedure is for fish-eye image correction program, which has detailed notes as long as it is believed that the basis of a certain person can understand. However, there is some difference which did not finish, remain to be improved.

通过研究Linux的线程机制和信号量实现读者写者(Reader
通过研究Linux的线程机制和信号量实现读者写者(Reader-Writer)问题并发控制。
1)写-写互斥：不能有两个写者同时进行写操作；
2）读-写互斥：不能同时有一个线程在读，而另一个线程在写；
3）读-读允许：可以有一个或多个读者在读；
4）读者优先的附加限制：如果读者申请进行读操作时已有另一个读者正在进行读操作，则该读者可直接开始读操作；
5）写者优先的附加限制：如果一个读者申请进行读操作时已有另一个写者在等待访问共享资源，则该读者必须等到没有写者处于等待状态后才能开始读操作。
-By studying the Linux thread mechanism and semaphores realize readers who write (Reader-Writer) the issue of concurrency control. 1) to write- write mutex: Can not write at the same time there are two write operations 2) read- write mutex: Can not have a thread at the same time in reading and writing another thread 3) Reading- Reading of permit: can have one or more readers read 4) the priority of additional restrictions readers: If the readers apply for a read operation, there was another reader being read, the reader can be directly started reading operation 5) to write additional priority Restrictions: If an application for a reader reading write operation has been in waiting for another visit to a shared resource, the read
