这个是在ＯＰＥＮＣＯＲＥ上收集的wishbone总线的开发说明和指导，随着电子设计开源ＩＰ的大量应用，wishbone总线也越来越普及。-This is collected in OPENCORE Wishbone bus and guide the development of note, with the electronic design of a large number of open source IP applications, wishbone bus is also becoming increasingly popular.

随着现在社会的发展，人们都避免不了要到某些城市去公干或其他的事情。一旦你对这个城市不熟悉，你的出门就会举步维艰。打的，对于一些因公出差的人来说算不了什么，但是对于旅游者或是个人来说就不是很好的选择。-now with the development of society, people should not have to avoid certain cities for business or other matters. Once you are not familiar with this city, you will be difficult to leave home. Fight, some on official business who is nothing, But tourists or individuals is not a good choice.

PPP挑战握手认证协议(CHAP)，PPP【1】提供了点到点链路传输多协议数据报的标准方法。 在PPP中也定义了一种可扩展的LCP，允许协商认证协议，从而可以在进行网络层 协议传输之前对对端进行认证。 本文定义了一种PPP认证方法，该方法利用随机“挑战”和依据“挑战”和密钥 计算出的加密哈希“应答”来完成认证。 -PPP Challenge Handshake Authentication Protocol (CHAP), PPP [1] provides a point-to-point link multi-protocol data transmission of standard methods. In PPP also defines a scalable LCP to allow consultations authentication protocol, thereby conducting transmission network layer protocol before the end-to-end authentication. This paper defines a PPP authentication methods, The method using random "challenge" and the basis for "challenge" and calculated key encryption Hash "responsive" to complete certification.
