Abstract:
A method for clocked serial data transmission of data blocks of identical block length between a first and a second transmission device, comprising:a) sending a data block as a sent data block in a first block cycle from the first to the second transmission device, b) receiving the data block as a received data block at the second transmission device, and returning the received data block as a returned data block to the first transmission device, c) receiving the returned data block at the first transmission device, comparing the returned data block with the sent data block, and generating a comparison result during a second clock cycle, d) in a third clock cycle, d1) in case of a comparison result signaling correspondence, continuing the data transmission from the first to the second transmission device by sending a further data block, or d2) in case of a comparison result signaling non-correspondence, suspending the data transmission from the first to the second transmission device for the third clock cycle, and e) in the second transmission device, e1) in case of a detection of a single clock cycle with suspended data transmission, overwriting the received data block received in the first clock cycle with a next subsequent received data block following the suspended data transmission, or e2) in case of a detection of two successive clock cycles with suspended data transmission, overwriting the received data block and a data block received immediately following the received data block with the next subsequent received data block following the suspended data transmission and another data block received immediately following the next subsequent received data block, respectively.
