rc6_avr
DL : 0
AVR单片机的优化RC6 加密算法(速度快,其优化思想绝对值得学习) 在有128bytes RAM 的AVR单片机上执行 rc6 16/10/8(16 bit/10 rounds/8 bytes keys) * 对多数代码进行了 C 语言优化,对数据相关循环移位,模乘等用ASM优化 * 在4MHz无乘法器的AVR上得到平均 1172 Bytes/s的加解密速度。 * 编译器: AVR-G-AVR optimization RC6 encryption algorithm (faster, optimizing their thinking definitely worth learning) 128bytes of RAM in the AVR on the implementation of production 16/10/8 (16 bit/10 rounds / 8 bytes keys) * for the majority of code optimization of the C language the data related to cycle shift, mode used by other optimization * ASM 4MHz without the multiplier be average AVR 1172 Bytes / s speed encryption and decryption. * Compiler : AVR-G

///*** *** *** *** *** *** * //一、程序说明: //1, 24LC02器件地址是1010000R/W. //2, 数组写入24LC02采取页写方式. //3, 数组code从24LC02读出时采取自由读方式. //4, 采用4.00M晶体。 //5,采用软件I2C。 //二、硬件连接: //1, SDA------->23 pin.(当然你可以任意选择脚位) //2, SCL------->18 Pin.(当然你可以任意选择脚位) //3, PORTB----->数码管的段输出 //4, RD4,RD5,RC6,RC7------->数码管的位输出(数码管为共阴极)
