Abstract
PURPOSE: To shorten the selection time by previously selecting an euipment to which a signal is to be transferred next by using a timing signal in transfer during the transfer operation of one equipment and then by outputting a bus use permission signal at the same time as the end of the transfer.
CONSTITUTION: Once requenst signals are generated by equipment AWC, the contents are set to register 5 to perform selection operation 6 and equipment number A is selected and set to register 10 to send selective signal A out from decoder 7. At the timing when signal A has been removed by transfer tag 2, the contents of request signal line 2 is set to register 5. To send a transfer end signal, signal B is sent out immediately since next selective signal B is determined as an input to register 10. The time when signal B is selected is zero because it is done in parallel to the transfer of signal A. Similarly, the selection time for signal C is zero. Even if register 5 would be set at the trailing edge of the transfer tag, a next transfer equipment number is only determined as an input to register 10 until the transfer end signal after the selection time.
