摘要：
A signal processor comprises a plurality of processing circuits for carrying out various kinds of processing which differ from one another; a memory circuit provided commonly for respective processing circuits, and a control circuit for carrying out access control between the respective processing circuits and the memory circuit, characterized in that the control circuit carries out address control in different units in accordance with the respective processing circuits. Alternatively, the address control can reflect the different processing priority of different types of data. The processing circuits may be image data I/O means, audio data processing means, encoding/decoding means, error correction means and encoded data I/O means.
