Abstract
A virtual-to-virtual page table maps a main surface containing the actual data and a metadata or auxiliary surface that gives information about compression of the main surface. In order to access the metadata that corresponds to main surface, an additional virtual-to-virtual table may be used ahead of the regular page table mapping to avoid the need to pass the metadata base address and x, y coordinates across a pipeline which may result in multiple memory writes.
