Abstract

PURPOSE:To enhance both the transfer efficiency and the reliablity by securing a switch to the error correction control when many data errors exist due to the noise at the transmission line. CONSTITUTION:In the normal time, the transmission data of memroy 1 is transferred to unit 1 via control part 2, switch part 11, error detection code control part 3, transmission part 4, transmission line 5, reception part 6, error detection control part 7, switch part 15 anc control part 8 respectively. When the error occurrence frequency which is detected through control part 7 due to the noise increment at the transmission line exceeds the prescribed value, the switch of the control made is informed from control part 14 to the transmitter side. And the operation of part 4 is discontinued via control part 10 to switch both the transmitter and the receiver sides to the error correction mode. After this, the transmission data is transmitted via switch part 12 and control part 9 where the error correction code is added. And the date error is corrected at the receiver side via the error correction code and through control part 13.
