A graphics processing system for processing polygons includes a cache 25 with cache lines 30, 40 for storing data entries, each line having a tag 31, 41 for identifying the data stored in the line. The polygons have vertices with which pieces of vertex attribute data 43 are associated. The system also includes processing circuitry which writes, to a line in a first set of lines 30, data entries associated with pieces of vertex attribute data 43. The pieces of vertex attribute data 43 are associated with the vertices of a polygon. The processing circuitry also writes a tag 31 including a polygon identifier to identify the polygon associated with the data entries to the line in the first set of lines 30, and writes, to a second set of lines 40 of the cache 25, data entries associated with pieces of vertex attribute data 43. The processing circuitry also writes tags 41 including vertex identifiers to the second set of lines 40 to identify the vertices associated with the data entries. |
