摘要： A low-power display device is provided. The display device is provided with a plurality of display portions. A data driver circuit and an addition circuit are provided to have a region overlapping with the display portion. First analog data is output from the data driver circuit in the case where first digital data consisting of a first digital value is input to the data driver circuit, whereas second analog data is output from the data driver circuit in the case where second digital data consisting of a second digital value is input to the data driver circuit. The addition circuit generates analog data corresponding to digital data that has a high-order bit that is the first digital value and a low-order bit that is the second digital value, by adding the second analog data to the first analog data. An output terminal of the data driver circuit is directly connected to an input terminal of the addition circuit without through an amplifier circuit.

摘要： 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.

摘要： An object is to provide a semiconductor device that can maintain the connection relation between logic circuit units or the circuit configuration of each of the logic circuit units even after supply of power supply voltage is stopped. Another object is to provide a semiconductor device in which the connection relation between logic circuit units or the circuit configuration of each of the logic circuit units can be changed at high speed. In a reconfigurable circuit, an oxide semiconductor is used for a semiconductor element that stores data on the circuit configuration, connection relation, or the like. Specifically, the oxide semiconductor is used for a channel formation region of the semiconductor element.

摘要： To achieve versatility, a driver IC has a function of generating an analog data signal from an image signal input from the outside; a function of outputting the analog data signal from an output pin; and a function of setting the analog data signal as a data signal for alternating-current driving or for direct-current driving, in accordance with data of a digital signal input from the outside. For example, the driver IC can output data signals for alternating-current driving from output pins in odd-numbered columns and data signals for direct-current driving from output pins in even-numbered columns. Furthermore, the driver IC can output data signals for alternating-current driving or for direct-current driving from all the output pins. The driver IC can drive a liquid crystal panel, a self-luminous panel, and a hybrid display panel where one subpixel includes a liquid crystal element and a light-emitting element.

摘要： A command sequence is restarted from the middle even when supply of power supply voltage to an internal circuit in a wireless tag is temporarily stopped (a power flicker occurs). A register or a cache memory included in a signal processing circuit in the wireless tag continues to retain data even after the supply of power supply voltage is stopped. After the power flicker occurs, the signal processing circuit in the wireless tag is returned to the state before the supply of power supply voltage is stopped and can restart signal processing. Consequently, the command sequence can be restarted from the middle.
