Abstract: Aspects of the disclosure provide a video decoding system. The video decoding system can include a decoder core configured to selectively decode independently decodable tiles in a picture, each tile including largest coding units (LCUs) each associated with a pair of picture-based (X, Y) coordinates or tile-based (X, Y) coordinates, and memory management circuitry configured to translate one or two coordinates of a current LCU to generate one or two translated coordinates, and to determine a target memory space storing reference data for decoding the current LCU based on the one or two translated coordinates.
