代码说明:

 AHB总线规范是AMBA总线规范的一部分,AMBA总线规范是ARM公司提出的总线规范,被大多数SoC设计采用,它规定了AHB (Advanced High-performance Bus)、ASB (Advanced System Bus)、APB (Advanced Peripheral Bus)。AHB用于高性能、高时钟频率的系统结构,典型的应用如ARM核与系统内部的高速RAM、NAND FLASH、DMA、Bridge的连接。APB用于连接外部设备,对性能要求不高,而考虑低功耗问题。ASB是AHB的一种替代方案。

    Encryption has become a part and parcel of our lives and we have accepted the fact that data is going to encrypted and decrypted at various stages. However, there is not a single encryption algorithm followed everywhere. There are a number of algorithms existing, and I feel there is a need to understand how they work. So this text explains a number of popular encryption algorithms and makes you look at them as mathematical formulas.
