Abstract
A method is used to access a sub-region of a two or more dimensional data region, in which said region is composed of a patchwork of individually addressable tiles. A hardware assisted mechanism is used to address, reformat, and composite data from each tile to produce a row-major subregion data stream to the consuming device. This method abstracts information about how the desired region is stored and addressed, so that further processing steps can process the data as a contiguous two or more dimensional space without regard to how the data is composited. This is particularly useful for doing image processing on graphics processing systems where source data is often stored in separately managed and addressed tiles.
