1. A method of processing video data in a video decoding system, comprising:
receiving input data associated with a current picture comprising a plurality of Virtual Pipeline Data Units (VPDUs), wherein each VDPU is a fixed size;
performing a decoding process to decode Coding Units (CUs) in the current VPDU and generate decoded samples of the current VPDU, wherein each CU coded in a Current Picture Referencing (CPR) mode is decoded by fetching decoded samples in a reference block stored in a CPR referring buffer; and
updating the CPR referring buffer by storing the decoded samples of the current VPDU when finishing the decoding process of the current VPDU, wherein the CPR referring buffer is updated one VPDU by one VPDU.
