代入法的啟發示搜索 我的代碼實現是:按照自然語言各字母出現頻率的大小從高到低(已經有人作國統計分析了)先生成一張字母出現頻率統計表(A)--------(e),(t,a,o,i,n,s,h,r),(d,l),(c,u,m,w,f,g,y,p,b),(v,k,j,x,q,z) ,再對密文字母計算頻率,并按頻率從高到低生成一張輸入密文字母的統計表(B),通過兩張表的對應關系,不斷用A中的字母去替換B中的字母,搜索不成功時就回退,在這里回朔是一個關鍵。

The PCI Local bus concept was developed to break the PC data I/O bottleneck and clearly opens the door to increasing system speed and expansion capabilities. The PCI Local bus moves high speed peripherals from the I/O bus and places them closer to the system’s processor bus, providing faster data transfers between the processor and peripherals. The PCI Local bus also addresses the industry’s need for a bus standard which is not directly dependent on the speed, size and type of system processor. It represents the first microprocessor independent bus offering performance more than adequate for the most demanding applications such as full-motion video.

因IAR公司曾經發布的IAR MakeAPP也具有很好的針對AVR單片機外圍I/O口通過友好的GUI界面配置產生C源碼驅動。但現在已經停止發布了,且只支持少數幾個器件。本文件幾乎攘括AVR單片機所有芯片簇,配置IO口自動產生C源碼……還有文檔說明和.NET框架。希望給你的開發工作帶來意外的驚喜。
