made by: kangkai data:2008.11.23 this one is used to test arm7 str71x. use a led to test GPIO. a---------P0.0 b---------P0.1 c---------P0.2 d---------P0.3 e---------P0.4 f---------P0.5 g---------P0.6 just run it and you will see the led to show 0-9 all the time.

實(shí)現(xiàn)IDEA加密算法與解密算法 IDEA(International Data Encryption Algorithm)是瑞士的James Massey,Xuejia Lai等人提出的加密算法,在密碼學(xué)中屬于數(shù)據(jù)塊加密算法(Block Cipher)類。IDEA使用長(zhǎng)度為128bit的密鑰,數(shù)據(jù)塊大小為64bit。從理論上講,IDEA屬于“強(qiáng)”加密算法,至今還沒(méi)有出現(xiàn)對(duì)該算法的有效攻擊算法。

measure through the cross-entropy of test data. In addition, we introduce two novel smoothing techniques, one a variation of Jelinek-Mercer smoothing and one a very simple linear interpolation technique, both of which outperform existing methods.
