Communication interface |
摘要 |
A communication interface for interconnecting a computer with at least one other device has a link output circuit and a link input circuit. A link output on one device is connected to a link input on another device by a data line 25 and a parallel strobe line 26. Data is transmitted on the data line 25 in serial bit strings forming a succession of tokens of predetermined lengths. Signal transitions are provided on the parallel strobe line 26 where no signal transition occurs on the data line 25. Each token includes a bit indicating the length of the token and a parity bit providing a check on bits in a preceding token. <IMAGE> |
