In this paper, we propose an efficient GMC hardware architecture for MPEG-4 ASP@L5. Based on analysis of affine model, the proposed memory arrangement and cascaded scheduling reduce the impact of irregular memory access and improve processing ability. It can process 30 fps at only 25 MHz. The implementation result shows that total gate count is 19.3K and internal memory size is 1.28Kb. It is suitable to be integrated into MPEG-4 ASP encoders and decoders. © 2005 IEEE.application/pdf161647 bytesapplication/pdfAdvanced Simple Profile; Advanced simple profiles; Affine model; Coding tools; Encoders and decoders; Gate count; Global motion compensation; Hardware architecture; Internal memory; Memory access; Processing ability; Motion compensation; Motion Picture Experts Group standardsconference paper10.1109/ISCAS.2005.14649582-s2.0-67649090846
