Inhalt:
In this work-in-progress paper we present a new scheme for multiple soft- and timing error monitoring in CPU pipelines. This scheme is based on combining a time redundancy technique (schadow register) and an information redundancy technique (Error Detecting and Correcting Codes). The scheme fault coverage includes multiple transient (SET, SET) and timing errors. The use of this scheme in building self-correcting CPU pipelines will be then presented.
