Zusammenfassung:When storing data of an array of data in memory in a graphics processing system, respective memory regions are allocated for storing blocks of the data array, with the allocated region of memory for a block of the data array corresponding to a maximum possible size of the block of the data array when compressed, and being divided into a plurality of memory allocation sub-blocks, having at least one sub-block having a first, larger size and at least one sub-block having a second, smaller size. Blocks of the data array are compressed using a compression scheme, with each compressed block being stored in one or more of the sub-blocks of its allocated memory region.
