Abstract
An AD converting apparatus which is provided with a data update flag 3b for storing a first value ('1') when an analog signal is newly converted by an AD converter 1 to digital data and is stored into a data register 3a, and for storing a second value ('0') when the contents of the data register 3a are read out externally in a state under which the first value has been stored, and which eliminates a wasteful operation such that the data having already been used is used again to perform an arithmetic operation, by building in a hardware capable of indicating whether the data after AD conversion has already been used once or not, and thus improving processing speed as a whole; and a data processor in which the AD converting apparatus is built in.
