摘要:
An apparatus may include a memory to store a set of triangle vertices in a triangle, a processor circuit coupled to the memory and a cache to cache a set of triangle vertex indices corresponding to triangle vertices most recently transmitted through a graphics pipeline. The apparatus may also include an autostrip vertex processing component operative on the processor circuit to receive from the memory the set of triangle vertices, compare an index for each vertex of the set of triangle vertices to determine matches to the set of cached triangle vertex indices, and shift a single vertex index into the cache, the single vertex index corresponding to a vertex miss in which a given vertex of the set of triangle vertices does not match any vertex index of the set of cached triangle vertex indices when exactly two matches to the set of cached triangle vertex indices are found.
