AHB AES with DMA (70122)
The United States Government designed the Advanced Encryption Standard (AES) in 2000 to replace the older Data Encryption Standard (DES). AES is a symmetric block cipher which means that the same key is used for both encryption and decryption of the data block.
For further information, refer to: Federal Information Processing Standards Publication 197, November 26, 2001, Announcing the ADVANCED ENCRYPTION STANDARD (AES).
The AHB AES Encryption/Decryption Engine is a configurable core that interfaces to an AHB microprocessor bus. To accommodate a wide variety of system requirements, the Engine can be generated in one of three configurations: Low Gates, Mid Gates and High Gates.
The register interface of the AHB AES Engine is accessed via an AHB Slave interface. Once the Engine has been configured and enabled, an AHB Master interface is used to transfer data to/from system memory using DMA transfers. The core reads from a programmable source location in system memory into an internal Input FIFO, performs the desired action (encryption or decryption) on the data and stores the result in an internal Output FIFO. Lastly, the contents of the Output FIFO are written to a programmable destination location in system memory.
A maskable interrupt can be enabled to notify the processor when all DMA transfers are complete, and the output data has been transferred to system memory.
