Abstract
A graphics processorincludes after its tile rendering logic, a transaction elimination unitthat includes data block generation logicand block comparison logic. The block generation logicgenerates data blocks from the rendered tiles produced by the tile rendering logic. The data blocks are then stored in buffers. Comparison logicthen compares a new data block with the previous data block (which will already be stored in the buffers), and generates an output metadata bit indicating whether the blocks can be considered to be the same or not, on the basis of the comparison. The meta-data output bits are stored appropriately in a meta-data bitmapin main memorythat is associated with the output data array in question. If the blocks are determined to be different by the comparison logic then the new data block is written from the buffersto the frame bufferin the main memory. On the other hand, if the two blocks are considered to be similar to each other, the new block is not written into the data array in the frame buffer
