序列对齐 Compare a protein sequence to a protein sequence database or a DNA sequence to a DNA sequence database using the Smith-Waterman algorithm.[.wat815.] \fCssearch3\fP is about 10-times slower than FASTA3, but is more sensitive for full-length protein sequence comparison.

用多线程同步方法解决读者阅览问题 1) 每个读者进入阅览室后,即时显示“Entered” 及其线程自定义标识,还同时显示阅览室共有几名顾客及其所坐的位置。 2) 至少有10个读者,每人阅览至少3秒钟。 3) 多个读者须共享操作函数代码。 2总的设计思想及系统平台、语言、工具: 设计思想:程序设定的是10个读者和5个座位,对读者进行编号,依次进入阅览室读书,为每一座位列一表目,包括座号和读者号等,读者离开时要登出,即消掉登记的信息。 系统平台:LINUX 语言:C语言 工具:vi编辑器、gcc编译器 操作系统:linux操作系统 调试工具:edit、masm、link、debug. 3数据结构与模块说明(功能与流程图) 数据结构 int count=0 //记录阅览室读者数量 sem_t full //定义阅览室座位信号量 int seat[5] //用数组表示座位 pthread_t reader[10] //定义读者线程 pthread_mutex_t mutex //定义互斥量 3.2功能说明 可以标识读者,随机为读者设置在阅览室的读书时间 可以显示阅览室读者的人数 可以显示读者所坐的位置,座位状态以及列出空座位

The C++ standard library provides a set of common classes and interfaces that greatly extend the core C++ language. The library, however, is not self-explanatory. To make full use of its components - and to benefit from their power - you need a resource that does far more than list the classes and their functions.

The download includes the kernel source code, and a demo application for EVERY RTOS port. See http://www.freertos.org/a00017.html for full details of the directory structure and information on locating the files you require. The easiest way to use FreeRTOS is start start with one of the demo application projects. Once this is running the project can be modified to include your own source files. This way the correct files and compiler options will be automatically included in your application. + The Source directory contains the real time kernel source files for every port. The kernel itself is only 3 files. + The Demo directory contains the demo application source files for every port. + The TraceCon directory contains the trace visualisation exe file. See the readme files in the respective directories for further information.

This sample displays a basic integer calculator powered by the 8051 microcontroller. Although Keil C51 has a full floating point math library the evaluation version is restricted to 2k of object code, so we have constrained this sample to integer maths in order to fit within this limit. The program for this design was written in C using the Keil uVision 2 IDE for which Proteus VSM provides a Debug Monitor driver. Instructions for configuring Proteus to run in conjunction with the Keil environment can be found by editing the 8051 microcontroller on the schematic (point at it and press CTRL-E) and then clicking on the help button on the Edit Component dialogue form.

就像在嵌入系统中使用C语言替代汇编一样,在嵌入系统中使用RTOS是大势所趋。原因主要是现在在大多数情况下编程效率比执行效率重要(单片机便宜嘛)。但纵观51的RTOS,keil c51 所带的RTX Full 太大(6k多),且需要外部ram,又无源代码,很多时候不实用。RTX Tiny虽然小(900多字节),但是任务没有优先级和中断管理,也无源代码,也不太实用。而ucosII虽有源代码,但是它太大,又需要外部ram,所有函数又必须是重入函数,用在51这类小片内RAM的单片机上有点勉强。于是,我借鉴ucosII和RTX Tiny编写了Small RTOS 51,虽然它为51系列编写,但是它还是比较容易移植到其它CPU上。
