1.1设计目的及要求  
1.1.1设计目的  
运用面向对象程序设计知识，利用C++语言设计和实现一个字符串处理系统  
1.1.2设计要求  
要求具备如下主要功能：  
字符串的输入与输出  
求字符串的长度  
判断字符串是否为空  
将字符串置空  
字符串比较  
字符串赋值  
求指定位置的字符  
字符串合并  
字符串截取  
在指定的字符串中1，查找或替换字符串2

通过利用高效访存指令,能够提升循环执行效率的零开销循环机制,指令重排技术,结合具体功能函数的循环特性,展开针对字符串与内存处理函数的指令级并行性挖掘.实验结果表明,这些库函数的优化效率能够达到硬件平台提供函数性能理论运行时间的1.5倍以下,本文转载自http://www.biyezuopin.vip/onews.asp?id=14637对BWDSP平台整体性能提升具有重要意义.
