A method for performing Tile to Raster (T2R) conversion includes: receiving tile input data including a stream of a plurality of tiles each having a tile height, a tile input width, a macroblock width (MBW), and data bits; segmenting the tile input data based on a total number of virtual square tiles; segmenting a Tile Buffer (TB) into one or more of the virtual square tiles based on the received tile input data; and performing a raster-scanning operation on each of the segmented tile input data and the segmented TB based on the total number of virtual square tiles to generate raster data.

In a system and method for write hazard handling a memory management unit policy is pre-computed for a write request using an address that is at least one clock cycle before data. The pre-computed memory management unit policy is registered and used for controlling a pipeline stall to ensure that a non-bufferable write is pipeline-protected, so that no non-bufferable location is bypassed from within the pipeline, and so that a subsequent non-bufferable read will get data from a final destination. A read request is bypassed only after a corresponding write request is updated in a write pending buffer. The write request is decoded with the write request aligned to data. The write request is registered in the write pending buffer. Arbitration logic is allowed to force the pipeline stall for a region that will have a write conflict. Read requests are stalled to protect against write hazards.
