The DHRY program performs the dhrystone benchmarks on the 8051. Dhrystone is a general-performance benchmark test originally developed by Reinhold Weicker in 1984. This benchmark is used to measure and compare the performance of different computers or, in this case, the efficiency of the code generated for the same computer by different compilers. The test reports general performance in dhrystones per second. Like most benchmark programs, dhrystone consists of standard code and concentrates on string handling. It uses no floating-point operations. It is heavily influenced by hardware and software design, compiler and linker options, code optimizing, cache memory, wait states, and integer data types. The DHRY program is available in different targets: Simulator: Large Model: DHRY example in LARGE model for Simulation Philips 80C51MX: DHRY example in LARGE model for the Philips 80C51MC

Boost provides free peer-reviewed portable C++ source libraries. We emphasize libraries that work well with the C++ Standard Library. Boost libraries are intended to be widely useful, and usable across a broad spectrum of applications. The Boost license encourages both commercial and non-commercial use. We aim to establish "existing practice" and provide reference implementations so that Boost libraries are suitable for eventual standardization. Ten Boost libraries are already included in the C++ Standards Committee s Library Technical Report (TR1) as a step toward becoming part of a future C++ Standard. More Boost libraries are proposed for the upcoming TR2. Boost works on almost any modern operating system, including UNIX and Windows variants. Follow the Getting Started Guide to download and install Boost. Popular Linux and Unix distributions such as Fedora, Debian, and NetBSD include pre-built Boost packages. Boost may also already be available on your organization s internal web server.

The XC226x derivatives are high-performance members of the Infineon XC2000 Family of full-feature single-chip CMOS microcontrollers. These devices extend the functionality and performance of the C166 Family in terms of instructions (MAC unit), peripherals, and speed. They combine high CPU performance (up to 80 million instructions per second) with extended peripheral functionality and enhanced IO capabilities. Optimized peripherals can be adapted flexibly to meet the application requirements. These derivatives utilize clock generation via PLL and internal or external clock sources. Onchip memory modules include program Flash, program RAM, and data RAM.

Skype4Java开发指南 Skype4Java架构 Skype4Java提供了一个较为完善的开发体系，使您可以非常容易地使用Java开发Skype外壳程序。 Skype插件程序与Skype的通信都是基于一些文本命令来完成的。因此，要想开发Skype的插件应用，就需要依靠不同操作系统平台的系统调用，发送Skype平台的相应命令来实现。 Skype4Java在最底层，也是通过操作系统的系统调用来完成消息的发送。针对异构平台，Skype4Java提供了不同平台的底层实现，而Skype4Java的使用者不用管具体的操作系统平台。因为抽象父类Connector类的静态方法getInstance()具体判断当前操作系统是什么平台，采用简单的工厂模式，返回相应平台的子类对象，如OSXConnector.，LinuxConnector, WindowsConnector, Win32Connector等，这些都是Connector类的子类。Connector及其子类即实现了一些系统调用的方法，其中被重载的一系列execute（）方法最终调用不同子类的sendCommand (String command)方法来实现了不同平台的消息发送。 而对于一些数据的接收和处理全局都是采用事件监听的机制（观察者模式），用于完成数据的接收，处理机制的调用，错误的处理等。 Skype平台利用错误消息机制提供了出错的处理。因此，在我们的错误处理中，只需分析错

在C++中open一個output file有兩種方式，一種是使用member function open( )，另外一種是使用constructor給予檔案名稱和open mode。今若欲open一個名為client.dat的output file，試分別寫出該兩種方式open此檔案的statements.(包括include header file，物件的宣告，open指令等)

gcclib This gcc 1.40 suits for Linux kernel 0.11 - 0.95 Installtion hints ----------------- This suit contains include.taz, local.taz and this README file. You must download the bootimage and rootimage and install them first. The include.taz contains all the include files for using with gcc 1.40. The local.taz contains all the gcc tools & libs stored in two sepearted directories: /usr/local/lib /usr/local/bin You should copy the linux/ asm/ sys/ subdirectories into the include directory from the corresponding kernel source. Installation ------------ Goto the /usr directory. Untar the include.taz to the directory /usr/include. Untar the local.taz to the directory /usr/local. That s it! Example: -------- cd /usr tar zxvf include.taz tar zxvf local.taz

在程序中需要使用到的字符串大致可以分为两大类，一类是创建之后不需要做修改和变动的字符串常量，另一类则是创建之后需要添加，插入和修改等更改的字符串变量。在java中，对于字符串常量对象则使用String类，它提供了许多诸如比较（compareTo），查找（indexOf）之类的操作，而对于字符串变量对象则使用StringBuffer类，它提供了扩充（append），插入（insert）等操作。
