PURPOSE:To keep high transfer efficiency, by reconnecting a request signal after queue, if the preparation for transfer is not finished when the request is read out from the queue. CONSTITUTION:A transfer control section 5 reads out a request signal from a queue memory 6 in the order of write. When the preparation for transfer is finished, a memory address corresponding to a channel is generated to a memory address forming section 7 through a memory address control line 107 and the data transmission is instruced trough a data transmission control line 109 to a data transmission section 4 at the same time. If the preparation of transfer is not finished, the control section 5 controls a request signal changeoever switch 9 and rewrites the request signal read out to the memory 6 through a rewrite line 105. |
