Abstract
PURPOSE: To control many communication lines with one control unit, by transferring directly receiving data from the communication control unit to the buffer for message processing on the main memory and by eliminating the buffer for editing on the main memory.
CONSTITUTION: Main memory 3 and communication control unit 1 are connected by data bus 73 to transfer directly receiving data from unit 1 to receiving buffer 74 for message processing on memory 3. That is, byte assembling and decomposing part 51 of unit 1 monitors receiving data from communication line 52, and reports detection of the start flag pattern to control part 54 when the start flag pattern is detected. Control part 54 updates contents of memory block designating part 59. When data receiving of frames is started, addresses, information, and so on are transferred from the memory block, which is designated by designating part 59, to buffer 74 on memory 3. As a result, the buffer for editing on memory 3 can be eliminated, and many communication lines can be controlled by one control unit.
