On the Implementation of MPEG-4 Motion Compensation Using the TMS320C62x
This application report describes the implementation of MPEG-4 motion compensation on the Texas Instruments (TI) TMS320C62x digital signal processor (DSP). MPEG-4 is a standard for coding of audiovisual information being developed by the Motion Picture Experts Group (MPEG).
MPEG-4 became an International Standard in December 1998. Motion compensation is a basic component of MPEG-4 and other video compression standards such as MPEG-1, MPEG-2, H.261, H.263, and H.263+. Code development flow to increase performance is discussed. Implementation issues, such as memory access pattern and code size versus performance, are also examined.
