An RTE ring structure.
The producer and the consumer have a head and a tail index. The particularity of these index is that they are not between 0 and size(ring)-1. These indexes are between 0 and 2^32 -1, and we mask their value when we access the ring[] field. Thanks to this assumption, we can do subtractions between 2 index values in a modulo-32bit base: that's why the overflow of the indexes is not a problem.
