摘要:
Each of processors has a barrier write register and a barrier read register. Each barrier write register is wired to each barrier read register by a dedicated wiring block. For example, a 1-bit barrier write register of a processor is connected, via the wiring block, to a first bit of each 8-bit barrier read register contained in the processors, and a 1-bit barrier write register of another processor is connected, via a wiring block, to a second bit of each 8-bit barrier read register contained in the processors. For example, a processor writes information to its own barrier write register, thereby notifying synchronization stand-by to the other processors and reads its own barrier read register, thereby recognizing whether the other processors are in synchronization stand-by or not. Therefore, a special dedicated instruction is not required along barrier synchronization processing, and the processing can be made at a high speed.

One data processor is provided with an interface for realizing connection with the other data processor. This interface is provided with a function for connecting the other data processor as a bus master to an internal bus of the one data processor, and the relevant other data processor is capable of directly operating peripheral functions that are memory mapped to the internal bus from an external side via the interface. Accordingly, the data processor can utilize the peripheral functions of the other data processor without interruption of the program being executed. In short, one data processor can use in common the peripheral resources of the other data processor.

An on-board optical sensor apparatus includes an optical sensor, an optical sensor cover, and a controller. The optical sensor has a lens. The optical sensor cover includes a holder and a washer nozzle. The holder holds the optical sensor. The washer nozzle performs a washing operation to wash a lens surface of the lens of the optical sensor or a glass surface of a cover glass located facing the lens by spraying a washer fluid, supplied from a washer fluid tank, onto the lens surface or the glass surface. The controller controls the washing operation of the washer nozzle.

A monitor system for a vehicle includes a camera, a display, a failure detection device, a report device, and a report control device. The camera captures an image of an area around the vehicle. The display displays the captured image to a driver of the vehicle. The failure detection device detects a failure of a function that allows the display to display the captured image. The report device reports the failure of the function to the area around the vehicle. The report control device controls the report device in such a manner that the report device reports the failure of the function in response to detection of the failure by the failure detection device.

An on-vehicle film antenna is constructed with a loop antenna and a monopole antenna and attached to a vehicle windshield. The loop antenna has a first element set in length to correspond to a first radio wave of a first frequency band. One end of the first element is connected to a power supply near a border section between a vehicle chassis and the vehicle windshield, and the other end of the first element is connected to the vehicle chassis. The monopole antenna has a second element set in length to correspond to a second radio wave of a second frequency band. One end of the second element is connected to the power supply near the border section in common with the one end of the first element, and the other end of the second element is disconnected from the vehicle chassis.
