US Patent:

Filed:

Sep 14, 2007

Appl. No.:

11/855838

Inventors:

William Gene Bliss - Thornton CO, US
Gregory L. Silvus - Boulder CO, US
John P. Mead - Longmont CO, US
Thomas V. Souvignier - Longmont CO, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H03M 13/00

US Classification:

714755, 714784, 714792

Abstract:

Super block error correction code (ECC) adaptable to communication systems including hard disk drives (HDDs) and other memory storage devices. A means is presented by which a number of blocks of information can be organized, with a degree of ECC provided thereto, and transmitted via a signal into a communication channel. In some instances, the communication channel is coupled to a storage media as in the context of an HDD, and information is written to and read from the storage media via this communication channel (e. g. , “read channel”). This means is particularly well suited to applications that provide large amounts of data via any one transmission (e. g. , DVR/PVR (Digital/Personal Video Recorder)). A redundant block is generated using the information of each of a number of information blocks thereby provided extra ECC on a large portion of data, and that redundant block also undergoes ECC encoding.

Broadcom Corporation - Irvine CA

International Classification:

H03M 13/00

US Classification:

714758, 714752, 714755, 714800

Abstract:

A write channel includes a pre-encoding module that encodes write data to produce pre-encoded data. An error correcting code (ECC) module generates ECC data based on the pre-encoded data. A post-encoding module encodes the ECC data to produce post-encoded data. A combining module combines the pre-encoded data and the post-encoded data for writing to the storage medium.
