<p>An arrangement is disclosed for conditionally compensating for skewing in the reception of data words transmitted over duplicated data transmission links. Each data word is serially transmitted over two links of different lengths having the same destination. A first counter is provided for counting each of the bits of the data word received over the first link, and a second counter is provided for counting each of the bits of the data word received over the second link. When one of the counters reaches a predetermined number indicating that the complete data word has been received, a determination is made if the present count in the other counter is within an allowable number of counts of the predetermined number. If this relationship exists, then the system waits for the other counter to reach the predetermined number, and then both complete data words are serially compared and the data word is executed. However, if the transmission of the data word over one link is too much slower than over the other link, then the first complete data word is immediately gated out and executed without waiting for the complete reception of the data word over the other link.</p> |
