DEVICE AND METHOD FOR BUFFER PROTECTION

The present invention relates to overflow protection of a buffer of a first- in- first-out type, able to store a first number x of messages from the digital module. The method is characterised by creating and sending pace messages to the buffer from the digital module, addressed to the first module itself, an d keep track of the pace in which they are sent and received. The criterion fo r sending pace messages is based on the number of sent messages. The sending o f messages is halted if a criterion, based on the number of sent pace messages and the number of received pace messages, determines that there exists a ris k for overloading the buffer. The device comprises means for creating a pace message, a pace sender for sending the pace message, a receiver for receivin g the pace message, and means for halting the process of sending messages.
