Patent ID: 7804854

Claim:
A method for transmitting, between a monitoring circuit integrated with a microprocessor and an analysis tool, digital messages, each message comprising at least one data packet, the method comprising: a/ for each message of the digital messages, dividing each data packet of a digital message into at least one successive segments of a same predetermined size, each segment of the successive segments being classified according to at least one of the five following types of segments: a first type of segment, each segment classified as the first type containing a message start; a second type of segment, each segment classified as the second type containing intermediary data; a third type of segment, each segment classified as the third type containing a packet end; a fourth type of segment, each segment classified as the fourth type containing a message end; or a fifth type of segment, each segment classified as the fifth type being an empty segment; b/ sending, by the monitoring circuit, at a same time as each segment of the successive segments, an identification signal characterizing a type difference between a considered segment and a previous segment; and c/ reconstituting, by the analysis tool, the packets of the digital message by arranging end to end the successive segments containing data of a same packet; wherein a segment of the successive segments having both the start and the end of the digital message is classified as the fourth type of segment, and wherein, if the message that includes at least one data packet comprises a plurality of data packets and if a segment of the successive segments has both the start of the digital message and the end of a first packet among the plurality of packets of the digital message, the segment is classified as the third type of segment.
