Delphi写的base64算法程序--Base64 algorithm program writed by Delphi

设f(x)=1+x+x2+x5+x27，试分别写出实现下列移位寄存器的程序： 以f(x)为联接多项式的DSR； 以f(x)为联接多项式的LFSR。 可供选择的联接多项式： f1(x)=1+x+x4+x6+x30； f2(x)=1+ x3+ x31； f3(x)=1+ x6+ x31； f4(x)=1+ x7+ x31； f5(x)=1+ x13+ x31； -Let f (x) = 1 x x2 x5 x27, respectively try to write the following Shift Register : f (x) connected to the DSR polynomial; f (x) for connectivity polynomial LFSR. Connection options polynomial : f (x) = 1 x x4 x6 x30; F2 (x) = 1 x3 x31; f3 (x) = 1 x6 x31; f4 (x) = 1 x11 x31; f5 (x) = 1 x13 x31;
