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
