OPTIMIZATION OF A STORAGE SYSTEM CONTAINING ECC AND SCRAMBLE ENGINES

摘要

A method for selecting the scrambling and descrambling data transmitted in a storage system containing ECC and scramble engines with a seed table is disclosed and the steps comprises: encoding a data sent from a HOST interface by an ECC encoding engine and transmitting the data to a LFSR scramble engine; scrambling the data by the LFSR scramble engine and transmitting to a storage device; creating a seed value and transmitting the seed value to a seed table by the LFSR scramble engine; receiving the seed value from the seed table and the scrambled data from the storage device by a LFSR descramble engine, and descrambling the scrambled data based on the seed value and transmitting to an ECC decoding engine; and decoding the descrambled data received from the LFSR descramble engine and then acquiring the original data sent from the HOST interface.

1. A method for selecting the scrambling and descrambling data transmitted in a storage system containing ECC and scramble engines with a seed table, the steps comprising:
step S1: encoding a data sent from a HOST interface by an ECC encoding engine and transmitting the data to a LFSR scramble engine; step S2: scrambling the data by the LFSR scramble engine and transmitting to a storage device; step S3: creating a seed value and transmitting the seed value to a seed table by the LFSR scramble engine; step S4: receiving the seed value from the seed table and the scrambled data from the storage device by a LFSR descramble engine, and descrambling the scrambled data based on the seed value and transmitting to an ECC decoding engine; and step S5: decoding the descrambled data received from the LFSR descramble engine and then acquiring the original data sent from the HOST interface.
