Description: 原创：vxworks的消息队列
一个任务运行时的数据和状态怎么告诉其他任务？信号量为任务间同步和互斥提供了提供了高效的方法，但它不能携带更多的任务信息。因而需要使用更高级的通讯方式，即消息队列和管道。这节主要讲消息队列。-Original: vxworks task message queue for run-time data and how to tell the status of other tasks? Semaphore for inter-task synchronization and mutual exclusion provides a way to provide a highly efficient, but it can not carry more information of the task. Therefore need to use more advanced means of communication, that is, message queue and the pipeline. This section stresses the main message queue.

Description: 内存管理实验程序。
要求 ：
使用 Windows XP的 API 函数，编写一个包含两个线程的进程，一个线程用于模拟内存
分配活动，一个线程用于跟踪第一个线程的内存行为，而且要求两个线程之间通过信号量实
现同步。模拟内存活动的线程可以从一个文件中读出要进行的内存操作，每个内存操作包括
如下内容：
1、时间：操作等待时间。
2、块数：分配内存的粒度。
3、操作：包括保留(reserve)一个区域、提交(commit)一个区域、释放(release)一个区域、回收(decommit)一个区域和加锁(lock)与解锁(unlock)一个区域，可以将这些操作编号存放于文件。-Experimental procedures for memory management.
Requirements:
Windows XP to use the API function to prepare a process contains two threads, a thread used to simulate the memory
Distribution activities, a thread for tracking the first acts of the thread of memory, but also between the two threads through the semaphore is
Are synchronized. Thread memory simulation activities can be read from a file to the memory operation, each memory operation, including
The following:
1, time: time to wait for the operation.
2, block number: the size distribution of memory.
3, steps: including the reservation (reserve) a region, the author (commit) to a single region, the release (release) a regional, recycling (decommit) a regional and locking (lock) and unlock (unlock) a region, can be operation code stored in the document.

Description: 通过研究Linux的线程机制和信号量实现生产者消费者（Bounded Buffer）问题的并发控制。
通过n个缓冲区组成缓冲池共同完成“生产和消费”任务，每个缓冲区存放一个产品，生产者将生产出的产品放入空缓冲区；消费者从满缓冲区中取出产品。一旦所有缓冲区均满时，生产者必须等待消费者提供空缓冲区。另外，对所有生产者和消费者线程来说，缓冲池是临界资源，即任何一个线程在对某个缓冲区进行“存”和“取”操作时须和其他线程互斥执行。
-By studying the Linux thread and semaphore mechanisms to achieve the producer consumer (Bounded Buffer) the issue of concurrency control. N the composition of a buffer zone through the buffer pool together, " production and consumption," the task, each buffer storing a product, producers will produce products Add empty buffer consumers out of the buffer zone from the full product. Once all the buffers are full, the producer must wait until buffer space consumers. In addition, producers and consumers of all threads, the buffer pool is a critical resource, that is, any thread of a buffer zone in the " deposit" and " check" operation to be mutually exclusive and the implementation of other threads.

Description: 用多进程同步方法解决生产者-消费者问题 设计目的:通过研究Linux 的进程机制和信号量实现生产者消费者问题的并发控制. 说明:有界缓冲区内设有20个存储单元,放入/取出的数据项设定为1-20这20个整型数. 设计要求:(1)每个生产者和消费者对有界缓冲区进行操作后,即时显示有界缓冲区的全部内容,当前指针位置和生产者/消费者县城的标识符.(2)生产者和消费者各有两个以上.(3)多个生产者或多个消费者之间须有共享对缓冲区进行操作的函数代码.-Synchronous multi-process solutions to producers- designed to consumer issues: the process by studying the mechanisms and Linux Semaphore producers to achieve concurrency control on consumer issues. Note: There are bounded buffer 20 storage units, Add/Remove the data item is set to 1-20 this 20 integer. design requirements: (1) Each producers and consumers to have the sector to operate the buffer zone immediately after showing the entire contents of the buffer zone sector, the current pointer location and producer/consumer identifier county. (2) producers and consumers have more than two. (3) a number of producers or more consumers must be shared between the operation of the buffer zone a function of the code.

Description: ：考虑VxWorks 的中断在具体实现上的特殊性，提出一个针对多块采集板系统的中断设计方案，把传统的中断服务程序分解为中断
服务程序和中断服务任务，利用信号灯进行同步，通过在中断服务任务中引入用户定义的优先级，增强系统处理多中断时的可靠性和实
时性。-】Considering the specificity in the specific realization of interrupt in the VxWorks, this paper proposes an interrupt treatment design of a
system consisted of multiple data acquisition boards. It divides the traditional Interrupt Service Routine(ISR) into interrupt service routine and
interrupt service task, and makes use of the semaphore to synchronize them. By introducing the priority that users define, the design enhances the
real-time performance and stability of the system.
