Error correction capability adjustment of LDPC codes for storage device testing |
摘要 |
Methods and structure described herein provide for adjusting an error correction capability of an LDPC error correction code. For example, the system of one embodiment includes a decoder adapted to decode data that has been encoded with a LDPC error correction code. The system also includes a detector communicatively coupled to the decoder and adapted to estimate bit values in the data prior to decoding by the decoder. The detector is further adapted to change bit values based on bit value estimations to reduce the error correction capability of the LDPC error correction code. The reduction in error correction capability is adjustable such that sector failure rates of storage devices may be incrementally analyzed. |
