The power consumption of a control device or a data processing system is reduced. Safety is enhanced. An electronic device is operated in a simple way. A control device includes an arithmetic circuit, an input unit, and a power management unit. The input unit includes a sensor element. The power management unit has a function of controlling supply and shutdown of power to the arithmetic circuit. The power management unit has a function of supplying power to the arithmetic circuit in response to a detection signal output from the sensor element. The sensor element includes one or more selected from an acceleration sensor, an angular velocity sensor, and a magnetic sensor. The arithmetic circuit includes a register. The register includes a first circuit and a second circuit. The register has a function of storing, in the second circuit, first data stored in the first circuit in a period during which the power management unit supplies power to the arithmetic circuit and retaining the first data, in a period during which the power management unit stops power supply to the arithmetic circuit. The arithmetic circuit has a function of generating second data with use of signal data output from the sensor element and the first data.

Control device and data processing system

A semiconductor device includes a sensor circuit including a sensor element, and a processing unit comprising a power management unit and an arithmetic processing circuit. The power management unit has a function of controlling power supply to the arithmetic processing circuit. The sensor circuit has a function of judging a sensed signal of the sensor element and supplying an interrupt signal to the processing unit in accordance with the judgment result. The power management unit has a function of restarting or stopping power supply to the arithmetic processing circuit in accordance with the interrupt signal.

Semiconductor device and control system

A plurality of display panels having a curved surface are placed in a limited space. Two, or three or more display panels are combined to form one display region having a T-shaped outer edge as one screen, and a driver can curve part of the display panel as appropriate so that the driver can see the screen easily. A first display panel or a second display panel has flexibility and includes a position adjustment function of curving an end portion. That is, by curving part of the display panel, the user can see the display panel easily. The in-car design can also be varied.
