Abstract
PURPOSE: To achieve a buffer memory of a large capacity not limited with a processor, by directly accessing the buffer memory with a wide address space with a simple address converting function, even if the address space of a microprocessor is narrow.
CONSTITUTION: A facsimile picture signal coded with a facsimile multiplexer 3 is transferred to a data transfer controller 2 with sub-block. Through the control of a microprocessor 6, the facsimile picture signal from the circuit 3 is stored in the memory 9 via a bus 104 at a multiplex transfer device 10. An address signal from this device 6 is address-converted 7 and stored in a header section in the memory 9, and the picture signal is read out and stored in a magnetic disc device 12. The picture signal in the device 12 is stored in the memory 9 through the control of a magnetic disc channel 11, the header is read out via the circuit 7 and compared with the information from a central processing device 1. As a result, when the picture signal is confirmed as a picture signal to be transmitted, the signal is transmitted to the device 3.
