A method for managing a buffer queue that stores a data queue, wherein the data queue comprises a set of n data elements, n being at least zero. A head pointer is stored at a first location, which may be in a cache controlled by a first processor. The head pointer indicates a head buffer of the buffer queue. The first processor reads the head pointer to determine the head buffer of the buffer queue when a data element is to be removed from the data queue. The first processor reads a next pointer of the head buffer to determine whether the data queue is empty. The first processor determines that the data queue is empty when the next pointer has a first value, which indicates that the head buffer is a dummy buffer. |
