PURPOSE:To make use of the system at high efficiency by exchanging ready signals and enable signals between a transmitting station and plural receiving stations and taking frame synchronism. CONSTITUTION:A frame of small capacity is prescribed as a unit of data transfer, and enable signals are transmitted from a transmitting station (data processing section) to all receiving stations when all ready signals from all receiving stations (data processing section) that require data come out, and at the same time data for one frame are sent out to a bus. Each receiving station generates next ready signal when the data for one frame are received, and such operation is repeated for each frame. Thereby, synchronism of the whole is taken for frame unit by ready signals and enable signals even if time of reception of data for one frame in receiving stations is different, and data of large capacity made by assembling of frame are transferred to plural receiving stations simultaneously. |
