摘要:
A method for operating an arithmetic unit having at least two computation cores. One signature register which has multiple inputs is assigned in each case to at least two of the at least two computation cores. At least one task is executed by the at least two of the at least two computation cores, an algorithm is computed in each task, results computed by each computation core are written into the assigned signature register, and the results written into the signature registers are compared.
摘要:
A control unit has two pairs of execution units, the two execution units of each pair redundantly processing the same program, and the output signals of each execution unit of one pair being compared to one another by a respective comparing unit, the respective comparing unit outputting an error signal when a difference in the output signals of the execution units of one pair occurs. A first pair of execution units are shut down when the error signal occurs for the first pair, and the control unit continues control operation using the second pair of execution units, and a pre-warning signal is output to the driver.
摘要:
A method for processing information and activities in a control and/or regulating system in which the control and/or regulating tasks are performed by a microcontroller, the control/regulating system including different components and the microcontroller receiving information which is evaluated and processed thereby, and at least one output signal being output as the result of control/regulating calculations. In a method for processing information and activities in a control and/or regulating system which may be implemented cost-effectively and nevertheless permits high computing power, the control and regulating tasks of the system are divided into component-specific task complexes, a first component-specific task complex being processed by a first processor core of the microcontroller and a second component-specific task complex being processed by a second processor core of the microcontroller.
摘要:
A memory system includes a writable data memory and means for recognizing an error in a data word read out from the data memory, correcting the error, and storing the corrected data word at a new address in a free area of the data memory.
摘要:
A system having multiple execution units and a method for its changeover are provided. The system having multiple execution units has at least two execution units, and may be changed over between a performance operating mode, in which the execution units execute different programs, and a comparison operating mode, in which the execution units execute the same program. The system has a scheduler, which is called by an execution unit to ascertain the next program to be executed. The remaining execution units are prompted to also call the scheduler if the program ascertained by the first called scheduler is to be executed in a comparison operating mode. A changeover unit changes over the system having multiple execution units from the performance operating mode into the comparison operating mode if the program to be executed ascertained by the last called scheduler is to be executed in the comparison operating mode, this ascertained program to be executed being executed as the program having the highest priority by all execution units after the changeover of the system into the comparison operating mode.
摘要:
A memory protection unit includes at least a first access control unit and a second access control unit programmed for controlling an access to a memory device. Further a method to operate a processing system comprising multiple processing devices and multiple memory protection units associated to the multiple processing devices, The access to the memory by a processing device is approved if first access control unit and second access control unit of the memory protection associated to the processing device approves the access and access is rejected if first access control unit or second access control unit rejects the access. The first access control unit is programmable by the associated processing device alone and the programming of the second access control unit is readable by an additional processing device which is to be used in a system with multiple programming devices, not the associate processing device.
