PURPOSE:To realize the mutual data conversion of a format of an information processing system and a format of a communication processing system by a simple constitution, in a bus conversion circuit being a device which transfers image data between an information processing part and a communication processing part. CONSTITUTION:This circuit is equipped with a memory 1 which stores the image data of the information processing system and the encoded data of the communication processing system, and a bus conversion circuit 3 which controls a bi-directional data transfer, and a data inversion and normal rotation between the memory 1 and a communication processing circuit 5 which processes the data of the communication processing system. The bus conversion circuit 3 is controlled by a control circuit 4 corresponding to the transferring operation between the memory 1 and the communication processing circuit 5, at the time of encoding the image data of the memory 1, and at the time of decoding the encoded data of the memory 1. |
