At least partially safety critical process control or regulating microprocessor system
2006
At least partially safety control critical processes or modulate microprocessor system (60), and two central processing units incorporated into the chip housing (1, 2), first and second bus system , at least one complete memory (7), a microprocessor system including the test data in one or more in the test data storage device to be linked to the data in the memory on the first bus system on the first bus system ( a 60), the test data storage device is smaller than the complete memory, bus system, micro including comparison and / or driver components to enable data exchange and / or comparison of data between two bus systems processor system (60). In the microprocessor system, one or more test data storage device is disposed on the first bus system, the second bus system, the test data storage device or used as a backup of the data in the memory on the first bus It does not have any of the memory. The present invention further relates to the use in a motor vehicle controller of the microprocessor system.
