Abstract: 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.

Abstract: An imaging device capable of executing image processing is provided. Analog data (image data) acquired through an imaging operation is retained in a pixel, and data obtained by multiplying the analog data by a given weight coefficient in the pixel can be extracted. The data is taken into a neural network or the like, whereby processing such as image recognition can be performed. Since an enormous amount of image data can be retained in pixels in an analog data state, processing can be performed efficiently.
