  • Device and method for buffer protection
    Patent number: 6643263
    Abstract: Overflow protection is provided for a buffer of a first-in-first-out type, able to store a first number of messages from a digital module. Pace messages are created and sent to the buffer from the digital module, addressed to the first module, and the pace in which they are sent and received is kept track of. The criterion for sending pace messages is based on the number of sent messages. The sending of 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 risk of overloading the buffer.
