Abstract: PROBLEM TO BE SOLVED: To provide a mechanism to minimize latency impact of data to be decrypted.
SOLUTION: Methods and apparatus for reducing the impact of latency associated with decrypting encrypted data are provided. Rather than wait until an entire packet of encrypted data is validated (e.g., by checking for data transfer errors), the encrypted data may be pipelined to a decryption engine as it is received, thus allowing decryption to begin prior to validation. In some cases, the decryption engine may be notified of data transfer errors detected during the validation process, in order to prevent reporting false security violations.

Abstract: A shared bus non-sequential data ordering method and apparatus are provided. A maximum bus width value and a minimum transfer value are identified. A minimumnumber of sub-transfers is identified responsive to the identified maximum bus width value and the minimum transfer value. A bus unit having a maximum number of chips to receive and/or send data receives data in a predefined order during multiple sub-transfers. During each data sub-transfer, a corresponding predefined word is transferred to each chip of the bus unit.
