Abstract
Performing soft error correction includes receiving a word at a soft correction engine capable of operating in more than one correction mode, identifying soft bit positions within the word, and automatically generating a number of possible results for the received word using combinations of the soft bit positions and the more than one correction modes. The soft correction engine may include a Golay engine.
Claims22
A method for performing soft error correction, the method comprising:
- receiving a word at a soft correction engine capable of operating in at least first and second correction modes that have different ratios of hard errors to soft errors, wherein a soft error relates to a faulty bit whose position is predictable and a hard error relates to a faulty bit whose position is not accurately predictable;
- identifying soft bit positions within the word;
- and
- generating, based on the identified soft bit positions, a number of possible results for the received word using combinations of the identified soft bit positions and the at least the first and second correction modes that have different ratios of hard errors to soft errors.

A system for performing soft error correction, comprising:
- means for receiving a word at a soft correction engine capable of operating in at least first and second correction modes that have different ratios of hard errors to soft errors, wherein a soft error relates to a faulty bit whose position is predictable and a hard error relates to a faulty bit whose position is not accurately predictable;
- means for identifying soft bit positions within the word;
- and
- means for generating, based on the identified soft bit positions, a number of possible results for the received word using combinations of the identified soft bit positions and the at least the first and second correction modes that have different ratios of hard errors to soft errors.
