ABSTRACT:
In an encoding or decoding process for compressible data, non-raster ordered bitstreams of transform data are rearranged in memory so later data access is contiguous, efficiently allowing processing in a single cache line. In an encoder, rearrangement can utilize a buffer copy that enables address calculation to performed only once per block.
