Image processing apparatus

摘要

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.
