PURPOSE:To enable downstream data transfer at the same time and to shorten the data transfer time of a microprocessor by reading data out of a FIFO memory. CONSTITUTION:When one of microprocessor systems on a data link sends data, a microprocessor 101 stores the data in the FIFO memory 102 and also stores the data in a downstream data link 142 at the same time. The reception of the data is known from a reception signal 115 outputted from the FIFO memory 102 and the received data stored in the FIFO memory 102 is read out and then processed. |
