DATA PROCESSING DEVICE

摘要

The invention relates to a data processing device comprising a processing unit (1), a memory component, and a mapping device (3) for mapping the addresses of a virtual memory (4) onto addresses of a physical memory (5) of the memory component, the execution of the mapping being caused by the processing unit (1). The inventive data processing device is characterised in that means (6) are provided for storing marginal conditions for errors in a memory (2) if an error occurs during the mapping in the mapping device (3), said memory being accessible for the processing unit.
