More Information
Summary:Methods and apparatus for error correction code (ECC) debugging may comprise detecting whether a bit error has occurred; determining which bit or bits were in error; and using the bit error information for debug. The method may further comprise comparing ECC syndromes against one or more ECC syndrome patterns. The method may allow for accumulating bit error information, comparing error bit failures against a pattern, trapping data, counting errors, determining pick/drop information, or stopping the machine for debug.
