Abstract
A device for temporarily storing data output from a register or data obtained by processing the output data, a processing method therefor, a program, and the like is provided. A circuit (hereinafter, referred to as a selective memory cell) in which a plurality of switches and a signal storing circuit are connected is provided in a data processing device. The selective memory cell can selectively store necessary data. A result of a frequently performed process is stored in the selective memory cell. A process whose result is stored can be performed by only outputting the stored data instead of performing the whole process; thus, input data does not need to be transferred, which can result in a reduction in processing time.
