RECEPTION DATA PROCESSING SYSTEM

PURPOSE:To speed up the collection of a received data and to improve the utilizing efficiency of the title system by implementing the procedure of reception data transmission executed between a communication adaptor and a processor and the data transmission between a data communication equipment and a communication adaptor in parallel. CONSTITUTION:When a data fetching request is given from a data communication equipment 100-1 to a communication adaptor 102-1, an asynchronous interruption signal is given from the communication adaptor 102-1 to the processor 104. Thus, the fetch start of a received data from the communication adaptor 102-1 to the processing unit 104 is informed. When the fetching of a reception data sent from the data communication equipment 100-1 is finished, it is given from the communication adaptor 102-1 to the processor 104 as the end report of a command SR by the asynchronous interrupt. The fetching of reception data of the data communication equipment 100-1 and the procedure to transmit the received data to the processor 104 are implemented in parallel in the communication adaptor 102-1. Thus, the collection of the received data is quickened and the utilizing efficiency of a computer system 200 is enhanced.
