  • Method and apparatus for exchanging data between transactional and non-transactional input/output systems in a multi-processing, shared memory environment
    Patent number: 6757756
    Abstract: The present invention relates to a queuing system, implemented in the memory of a computer by the execution of a program element. The queuing system includes a queue with a plurality of memory slots, a write pointer and a read pointer. The write pointer permits to enqueue data elements in successive memory slots of the queue. The read pointer permits to dequeue data elements from the queue memory slots for processing, where these data elements are potentially non-dequeuable. Upon identifying a non-dequeuable data element in a particular memory slot of the queue, the read pointer is capable to skip over the particular memory slot and move on to a successive memory slot.
