Abstract

Bus problems are generally the highest solid and intermittent failures in current processor systems, and detection and isolation are a major problem. Recovery for intermittent failures and isolation for solid failures is necessary. By adding error checking and correction (ECC) to a bus address and data lines, you will obtain full recovery for single-bit errors and isolation for multi-bit errors.
