20130198419 | LOCK-FREE FIFO - One embodiment of the present invention sets forth a technique that allows multiple producers and/or consumers to access a first-in first-out sub-system (FIFO) using a “lock-free” mechanism.

However, each producer and consumer is provided with an indication of whether their respective access was successful. Unsuccessful accesses may be retried in the following clock cycle, so that simultaneous accesses are serialized. | 08-01-2013 |
