Abstract
A bus control system for controlling intermultiprocessor communication by polling, comprising a listener response signal line for transferring an end answer signal from a listener circuit to a talker circuit immediately when the transfer of data between the talker and the listener is finished, without waiting for the completion of data transfer within the receiving processor, whereby the bus occupation period is shortened.
