1. 概述：

The IP core implements the NIST FIPS-197 Advanced Encryption Standard and can be programmed to either encrypt or decrypt 128-bit blocks of data using a 128-bit, 192-bit or 256-bit key. The IP has been carefully designed to require minimum logic resources rendering it an ideal solution for low power applications. This has been achieved by using an 8-bit data path size which means that 16 clock cycles are required to load/unload the 128-bit plaintext/ciphertext block. The encryptor receives the 128-bit plaintext block in 8-bit input symbols and generates the corresponding 128-bit ciphertext block in 8-bit output symbols using a supplied 128, 192, or 256-bit AES key. The pre-computed key values are read from an internal round key RAM. A key expander module is provided as an optional module to allow automatic generation and loading of the round key RAM. The decryptor implements the reverse function, generating plaintext from supplied ciphertext, using the same AES key as was used for encryption. The implementation is very low on latency, high speed with a simple interface for easy integration in SoC applications.
