PURPOSE:To shorten a processing time by storing a data on a processing queue in the main storage of a main processor after the processing is over and at the same time providing a table to a secondary processor to store the address of the processing queue of transmission of the data on the main storage. CONSTITUTION:A communication controller 3 consists of the main processor 1 and the secondary processor 2. The processor 2 secures the correspondence to the address of a main storage 1-2 corresponding to the processing queue stored in a buffer 1-1 after the generation of a transmission request. Then the processor 1 sets the head addresses of the corresponding addresses to the table 2-1 of the processor 2 in the order of earlier transmission. When the processor 2 receives the request of transmission from the processor 1, the processor 2 detects the first head address stored in the table 2-1 and transmits first the data on the corresponding head address of the storage 1-2 onto a circuit 4. The processor 2 repeats the transmission until all head addresses of the table 2-1 are through and informs the end of transmission to the processor 1. In such a way, the processing time is shortened with the controller 3.
