Abstract
A data processing machine including an instruction and operand processing complex. The instruction and operand processing complex generates results during execution of some instructions. When results are generated, a request to store the results in a high speed cache is generated. The cache receiving the request to store the results includes means for detecting errors in a line in the storage means to which the results are to be stored prior to writing the results to the line. If the line includes an error, a means for correcting the error reads to the line from the cache, corrects the error and restores the line. When the line is restored, the results are written to the cache and a correct ECC code is generated.
