Filed: 1987-03-11
Abstract: PURPOSE:To use a buffer while packing its memory from its end by discriminating the necessity of a received frame and resetting the address generating circuit designating the address of the reception buffer to be restored in case of an undesired frame. CONSTITUTION:A sequence circuit 4 selects the 1st buffer 5 and the 2nd buffer 7 alternately for each reception frame and gives a signal to corresponding address generating circuits 6, 8. The address generating circuit gives an address to each buffer and stores a reception frame.
