Abstract:
1. A method for synchronizing a data interchange in a semiconductor substrate integrated electronic circuit comprising a transmitter block and a receiver block connected through a communication network, comprising: generating a data signal having a transmission period on a first line, the data signal sent at a first instant from said transmitter block to be received by the receiver block; generating on a second line a congestion signal sent from the receiver block to the transmitter block when a congestion event of the receiver block occurs in order to interrupt the transmission of said data signal; and generating on a third line a synchro signal sent at a second instant from said transmitter block, this synchro signal indicating to the receiver block that the data signal on the first line comprises a new datum, wherein the congestion signal interrupts also the transmission of said synchro signal when a congestion event of the receiver block occurs, and wherein the second instant for sending said synchro signal for communication over the third line is delayed with respect to the first instant for sending the data signal for communication over the first line.
