Apparatus and method for reporting occurrences of errors in signals stored in a data processor

摘要

The present invention provides an apparatus for reporting errors in data stored in a memory apparatus of a data processor, comprising: first circuitry for storing multiple digital first signals; second circuitry for storing the multiple digital first signals and adapted for storing at least one digital second signal; third circuitry for transmitting the multiple digital first signals substantially from the first circuitry to the second circuitry; fourth circuitry for providing the at least one digital second signal, in the course of the transmitting of the first signals by the third circuitry, in response to an occurrence of one or more errors in one or more of the multiple digital first signals; fifth circuitry for transmitting the multiple digital first signals substantially from the second circuitry to the first means; and sixth circuitry adapted for receiving the at least one digital second signal in the course of the transmitting of the multiple digital first signals by the fifth circuitry and for providing at least one third signal in response to an occurrence of the at least one digital second signal.
