Abstract:
The speed at which encrypt and decrypt operations may be performed in a general purpose processor is increased by providing a separate encrypt data path and decrypt data path. With separate data paths, each of the data paths may be individually optimized in order to reduce delays in a critical path. In addition, delays may be hidden in a non-critical last round.
