Abstract

The invention relates to a microprocessor system (60) for controlling and/or regulating at least partly security-critical processes, which system comprises two central processing units (1, 2) integrated into a chip housing, a first and a second bus system, at least one complete memory (7) on the first bus system, and check data in one or more check data memories, said data being related to data of the memory in the first bus system. The check data memory is smaller than the complete memory. The bus systems comprise comparative and/or driver components which facilitate data exchange and/or comparison of data between the two bus systems. The one or more check data memories are arranged on the first bus system. On the second bus system, neither a check data memory nor a memory safeguarding data of the memory on the first bus is used. The invention also relates to the use of the inventive microprocessor system in automotive control devices.
