1. beep -- PWM测试 为 ADS1.2 下编译的项目, 在sdt2.51的ADW里调试，该程序运行后在57600的超级终端里按PC机键盘的“+”“-” 按键，可以听到BUZZ增大减小的声音。 2. key -- 按键测试 为 SDT2.51 下编译的项目, 在sdt2.51的ADW里调试，该程序运行后按FS44B0X上的按键key1 key2 key3 key4 相应的发光二极管亮 3 keyint -- 按键中断测试 该项目在SDT2.51下编译调试。主程序是while空循环，中断服务程序对应四个按键做相应的处理，key1 按键点亮D1灯，并在串口打印信息，因为没有加按键去抖动程序，所以，一次按键，产生几次中断。

由于电子商务广泛采用公开密钥技术，职能部门有必要对公钥加以管理。本文简要介绍了基于PKI的密钥托管技术及密钥托管代理的概念，分析了密钥托管的步骤，以及政府部门在密钥托管代理的帮助下强制访问信息的过程。 关键词：密钥托管 证书授权认证 公开密钥 公钥基础设施 托管证书 网络的安全问题得到人们的日益重视。网络面临的威胁五花八门：内部窃密和破坏，截收，非法访问，破坏信息的完整性，冒充，破坏系统的可用性，重演，抵赖等。于是公钥基础设施（Public Key Infrastructure，PKI）应运而生。PKI是电子商务和其它信息系统的安全基础，用来建立不同实体间的"信任"关系。它的基础是加密技术，核心是证书服务。用户使用由证书授权认证中心（Certificate Authority，CA）签发的数字证书，结合加密技术，可以保证通信内

雜湊法(Hashing)的搜尋與一般的搜尋法(searching)是不一樣的。在雜湊法中，鍵值(key value)或識別字(identifier)在記憶體的位址是經由函數(function)轉換而得的。此種函數，一般稱之為雜湊函數(Hashing function)或鍵值對應位址轉換(key to address transformation)。對於有限的儲存空間，能夠有效使用且在加入或刪除時也能快的完成，利用雜湊法是最適當不過了。因為雜湊表搜尋在沒有碰撞(collision)及溢位(overflow)的情況下，只要一次就可擷取到。

Expert Choice represents a significant contribution to the decision making process 工t assists a decision maker in solving complex problems involving many criteria and several courses of action . An Expert Choice solution to a problem reflects the expertise of the decision maker , not the computer . Behavioral scientists have spent many years studying the human mind and how it makes decisions . They have found that humans are influenced by their previous experiences and this causes them to have biases . Basic instincts , preferences and environmental factors also play key roles in how we analyze data and make decisions . There 15 way to remove these factors from human decision making , nor would we necessarily want to , but as the problems of our world become more and more complex , it 15 necessary for us to employ a framework to help make more logical and less biased decisions while still taking our feelings and intuition into consideration .

YSS915 (KP2V2) is an LSI for processing Karaoke voice signals. This LSI has an A/D converter (1 channel) for the microphone echo, and a memory for the microphone echo and key control. These features allow achieving the functions needed for the Karaoke system by using only one LSI chip. As for the microphone echoes, many other types of echoes are available in addition to ordinary ones so that YSS915 is applicable to various uses. In addition to these Karaoke programs, YSS915 is able to provide the Movie & Music programs, with which the surround effect is applied to the movie and music sources for giving the users more enjoyment. YSS915 is pin compatible with and register compatible with YSS903 (KP2V).
