Abstract:
Cache thrashing or over-accessing of a cache can be reduced by reversing the order of traversal of a triangle on different granularities. In the case where triangles are not grouped, the traverse order may be reversed on each triangle. In cases where triangles are grouped, the traversal order may be reversed with each group change. However, when motion is excessive, for example beyond a threshold, then the traversal order reversal may be disabled.
