Abstract
A communication device provides wireless communication between a controller in a motor vehicle and a network having at least one device external to the motor vehicle. The controller includes a computation device with at least two processor cores. Data interchange between the communication device and a first processor core takes place exclusively via a second of the processor cores.
Claims15
A controller of a motor vehicle in wireless communication with a network having at least one device external to the motor vehicle, comprising:
- a communication device providing the wireless communication with the network;
- and
- a computation device having
- a multicore processor with at least two processor cores, including a first processor core performing data interchange with the communication device exclusively via a second processor core that creates a demilitarized zone,
- a control unit, and
- a memory device with a shared memory area, addressable by the second processor core, provided for communication between the first and second processor cores, the second processor core having no access to memory areas other than the shared memory area and no access to the control unit that configures the memory device.
A motor vehicle in wireless communication with a network having at least one device external to the motor vehicle, comprising:
- a controller including
- a communication device providing the wireless communication with the network;
- and
- a computation device having
- a multicore processor with at least two processor cores, including a first processor core performing data interchange with the communication device exclusively via a second processor core that creates a demilitarized zone,
- a control unit, and
- a memory device with a shared memory area, addressable by the second processor core, provided for communication between the first and second processor cores, the second processor core having no access to memory areas other than the shared memory area and no access to the control unit that configures the memory device.
A method for operating a controller in a motor vehicle having a communication device for wireless communication in a network including at least one device external to the motor vehicle, and a computation device with at least two processor cores, said method comprising:
- interchanging data between the communication device and a first processor core in a multicore processor, exclusively via a second processor core of the multicore processor, that creates a demilitarized zone;
- communicating between the first and second processor cores via a memory device in the computation device having a shared memory area addressable by the second processor core;
- and
- preventing access by the second processor core to memory areas other than the shared memory area and to a control unit that configures the memory device.
