ABSTRACT:
In an image processing apparatus, an objective address signal is compared with at least one preceding address signal, provided prior to the objective address signal, to obtain a control signal. A unit of data corresponding to the objective address signal is read from a memory. A processor performs a predetermined processing to the unit of data to obtain renewal data. The renewal data are written to its original address in the memory. According to the control signal, a controller controls reading and writing access to the memory.
