DATA TRANSFER REQUEST SYSTEM

摘要

PURPOSE:To simplify the processing unit by providing a request transmission means and sending a transmission request of a transmission data outputted from a transmission section and an extracting request of a reception data outputted from a reception section to the processing unit via the same queue. CONSTITUTION:A transmission section 300 applies multiple processing to a transmission data sent in response to the request from the processing unit 100 and sends the result to plural communication lines 200. A reception section 400 applies multiple processing to the reception data reached from the plural communication lines 200 and gives a request of extraction to the processing unit 100. A request transmission means 500 sends the transmission request of a transmission data outputted from the transmission section 300 and the extraction request of the reception data outputted from the reception section 400 to the processing unit 100 via the same queue. Thus, the processing unit 100 has only to supervise the common request transmission means to extract the transmission request of the transmission data to the transmission section 300 and the extraction request of the reception data to the reception section 400 in the order of first-come to the same queue and the supervisory point for the transmission request and the extraction request is unified.
