摘要： A method of detecting manipulation of a programable memory device of a digital controller for a motor vehicle is described; data and control programs for operation of the controller and for control/regulation of certain functions of the motor vehicle can be stored in the memory device. To permit especially reliable detection of manipulation in the simplest possible way, in conjunction with each programing/reprograming operation of the programable memory device, information regarding the programing/reprograming operation is stored in a separate memory area of the memory device where only reading and programing are possible, and in order to detect manipulation, the content of the separate memory area is read out and compared with given information.

摘要： A method and a device for testing a computer core in a processor having at least two computer cores is described. The computer cores are connected to each other via an internal connecting system, both computer cores contributing toward the operating sequence of a machine. In the method for testing a computer core, with which a high error detection rate may be achieved in a minimum outlay of time, a test is run in one computer core, while a program for executing the driving operation of the motor vehicle is being processed in the other computer core at the same time.

摘要： A method is provided for controlling a microcontroller in a control unit in a motor vehicle, having a processor core, at least one read-only memory area and at least one rewritable memory area, at least one control program which is intended to be processed by the processor core being stored in the rewritable memory area. In order to provide a method for controlling a microcontroller in a control unit that better protects the verification of memories of the microcontroller against unauthorized intervention, a verification program is stored in a write-once memory area of the rewritable memory area and a service program is stored in the read-only memory area. The verification program is called by the control program via the service program at regular intervals and verifies at least part of the rewritable memory area. In addition, the service program resets a counter. A RESET of the control unit is triggered by the verification program when manipulation of the verified memory area is detected or by the counter in the event of counter overflow.

摘要： A method and apparatus for monitoring an electronic control system such that provision is made for the complete data of at least one memory to be read sequentially into an ECC unit, which can be filled very rapidly from the memory, and automatically checked there, with no need to transfer the complete data in time-consuming fashion to a processor; the ECC check width encompassing the data of a plurality of memory cells of the memory and being able to be a multiple of the read word width of the processor; an additional datum being created in each case for the data of a ECC check width and being storable in the memory, and the entire code/data region of the at least one memory therefore being able to be checked, outside the ongoing instruction accesses, by the fact that for each request by the processor for the contents of a single memory cell, the ECC unit is filled from the memory to the entire ECC check width including the additional datum; a check datum being created from the data of the complete ECC check width and the check datum automatically being compared, in the ECC unit, with the stored additional datum.

摘要： A method and a device for refreshing the memory content of at least one memory cell of a read-only memory is described. An embodiment of the present invention involves determining the instantaneous charge status of the memory cell; comparing the instantaneous charge status of the memory cell with a charge threshold (U_schw) which is greater than the reading charge (U_erh) sufficient for correct detection of the memory content of the memory cell; and raising the charge status of the memory cell if the instantaneous charge status of the memory cell is below the charge threshold (U_schw).
