Abstract

PURPOSE: To reduce facility in scale on the whole by transferring (n) pieces of data separately by an input device and output device for high-speed data and then by sharing the transfer circuit of the input device, data line and output device in time-division mode for low-speed data.
CONSTITUTION: When data are transferred between data processors 1 and 2, high- speed data are transferred separately by couples of high-speed data output devices 51W5n and 81W8n, and high-speed data input devices 71W7n, and 101W10n connected to control lines 3 and 4 respectively. For low-speed data, low-speed data output devices 211 and 241, low-speed data lines 221 and 251, and low-speed data input devices 231 and 261 are connected in common and this transfer circuit is shared in time-division mode, reducing the facility in scale on the whole.
