  • Method and system to share circular buffer without using locking mechanism
    Patent number: 6802066
    Abstract: A software buffer is implemented without using notoriously slow locking mechanisms by employing a so-called atomic microprocessor operation to increment a counter tracking the total number of messages inserted into the buffer by various processes. In this manner, a unique slot is guaranteed to be assigned to each respective message to be inserted. Additionally, a count of the total number of removed messages is used to handle situations where two messages are assigned the same slot due to buffer overflow.
