Abstract: A system may include a first device, a second device, a third device, and a serial link between the second device and the third device. The first device may be configured to deliver to the second device an information stream having a transmission fault tolerance associated with a transmission by the second device to the third device over the serial link. A related method may include, during the transmission over the serial link, phases for synchronization between the second and third devices, and during each synchronization phase, the first device may continue to deliver the information stream to the second device.

Abstract: A method for transmitting data in series includes producing a scrambled signal by applying a scrambling using a pseudo-random sequence to an incoming serial signal conveying the data and producing an outgoing serial signal. The scrambled signal is monitored to detect occurrences of one or more data patterns. In response to the detection of one or more occurrences, one or more actions are taken to protect data in the output signal.

Abstract: The invention relates to a method for serial data transmission, comprising the steps consisting in computing the running disparity (RD) of a bit stream that is being transmitted; when the running disparity reaches a threshold (T), computing a point disparity on a subsequent frame (S) of the stream; if the point disparity has the same sign as the threshold, inverting the states of the bits of the frame in the transmitted bit stream; and inserting into the transmitted bit stream a polarity bit having a state signalling the inversion.

Abstract: A device for transmitting a signal over a serial link includes a transmission processor to carry out, before transmission over the serial link, a scrambling process on successive initial packets of the signal to form a scrambled packet for each initial packet. The transmission processor includes an encoding circuit to carry out an encoding process on each initial packet to deliver an encoded packet. The encoding process includes, for each current initial packet starting from the second, encoding of the current initial packet with the preceding scrambled packet. Calculation circuitry determines, for each initial packet, a bit disparity of the encoded packet and determination of a cumulative bit disparity. Comparison circuitry carries out a comparison process involving the bit disparity of the encoded packet and the cumulative disparity, with the scrambled packet being the encoded packet or the inverted encoded packet, depending on the result of the comparison process.
