Abstract: An oscillator capable of quick startup is provided. A transistor is provided between an output terminal of a certain stage inverter and an input terminal of the following stage inverter included in the voltage controlled oscillator. With the use of the on resistance of the transistor, the oscillation frequency of the clock signal is controlled. While supply of the power supply voltage is stopped, a signal that is input to the input terminal of the inverter just before supply of the power supply voltage is stopped is stored by turning off the transistor. This operation makes it possible to immediately output a clock signal that has the same frequency as that before supply of the power supply voltage is stopped at the time when the power supply voltage is supplied again.

Abstract: A method for controlling power supply in a semiconductor device including a CPU and a PLD which can hold data even in an off state is provided. The semiconductor device includes a processor, a programmable logic device, and a state control circuit. The programmable logic device includes a first nonvolatile memory circuit and has a function of holding data obtained by arithmetic processing of the programmable logic device when it is turned off. The state control circuit obtains data on the amount of a task performed by the programmable logic device in accordance with an operation of the processor. The programmable logic device detects the state of progress of the task and outputs a signal to the state control circuit. The state control circuit monitors the amount of the task and the state of progress of the task and turns off the programmable logic device when the task is completed.

Abstract: An imaging device capable of image processing is provided. The imaging device can retain analog data (image data) obtained by an image-capturing operation in a pixel and perform a product-sum operation of the analog data and a predetermined weight coefficient in the pixel to convert the data into binary data. When the binary data is taken in a neural network or the like, processing such as image recognition can be performed. Since enormous volumes of image data can be retained in pixels in the state of analog data, processing can be performed efficiently.

Abstract: Provided is an electronic device whose display quality is independent of environment light. The electronic device is provided with an optical sensor, an acceleration sensor, and the like so that information including the brightness of external light, the angle of external light incident on the electronic device, and the orientation of the display portion in the electronic device is obtained, and the luminance and color tone of the display portion in the electronic device are corrected on the basis of the information. As the correcting method, calculation using a neural network is performed using the luminance and color tone meeting the preference of the user as teacher data and the obtained information as input data. The calculation result is reflected on the luminance and color tone of the display portion in the electronic device, whereby an image with display quality that suits the user's preference can be displayed.
