Abstract
A semiconductor device capable of performing filter processing while suppressing an increase in processing time is provided. The semiconductor device includes a microcontroller. The microcontroller comprises a CPU, a memory and a CAN-controller. The memory stores software. The CPU executes the software stored in the memory. The CAN controller is configured to add label information to the message information. The CAN routing software stored in the memory implements a filtering function for performing a filter processing for determining whether or not to route the message information by using the label information.
Claims19
A semiconductor device comprising:
- a storage circuit for storing software;
- at least one processing circuit for executing the software;
- and
- a controller configured to add additional information to message information received from an in-vehicle network,
- wherein the software includes a filtering function for performing a filter processing for determining whether or not to route the message information output from the controller by using the additional information.
A semiconductor device comprising:
- a storage circuit for storing software;
- at least one processing circuit for executing the software;
- and
- a controller configured to add additional information to message information received from an in-vehicle network;
- wherein the software includes:
- an application for executing processing independent of a microcontroller configuring the semiconductor device;
- and
- basic software for making the application independent of the microcontroller;
- wherein the basic software implements a filtering function for performing filter processing for determining whether to route the message information output from the controller with using the additional information in a network interface for enabling use of a protocol defining the in-vehicle network provided in a layer for abstracting hardware of the semiconductor device.
An information processing method comprising:
- adding additional information to message information received from an in-vehicle network;
- and
- using the additional information,
- performing a filter processing for determining whether or not to route the message information.
