Abstract

In a data store using error correction to correct single-errors and detect double-errors, an error frequency counter is used to indicate the rate at which single-errors are occurring. The error rate indicates amount by which the performance of the store degraded by correcting single errors. The error frequency counter is incremented each time a single-error occurs. An interval timer resets the counter after a predetermined time interval. The count is compared with a preset limit. An error frequency limit interrupt signal is generated when the count is equal to or greater than the error frequency limit. The interrupt signal causes a warning message to be printed.
