A flow controller selects a direction (encryption/decryption) for an AES core according to quality of service parameters and a number of data words in encryption and decryption data buffers. A direction ratio may be calculated as a function of the quality of service parameters and the number of data words in the encryption and decryption data buffers. The flow controller selects the direction to reduce a cost function. The cost function may be at a minimum when a ratio of words in the encryption and decryption data buffers is the same as the direction ratio. A key management unit supplies keys according to the selected direction to the AES cores. Multiple AES cores may be used.

QoS assisted AES engine for SSD controller

A logical address key is generated based at least in part on a logical address. Encoded data is generated by systematically error correction encoding the logical address key and write data. One or more physical addresses are determined that correspond to the logical address where the physical addresses that correspond to the logical address are dynamic. At the physical addresses, the encoded data is stored with the logical address key removed.
