Abstract

In a graphics processing system, when using a graphics texture that is stored in memory as YUV texture data, the YUV texture data is stored in the texture cache from which it is to be read when generating a render output such that the data values for a chrominance data element and its associated set of one or more luminance data elements of the texture are stored together as a group in the cache. The group of data in the cache is tagged with an identifier for the data values of the chrominance data element and its associated set of one or more luminance data elements that is useable to identify the chrominance data element and its associated set of one or more luminance data elements in the cache, and that is indicative of a position in the YUV graphics texture.
