Abstract

A real-time MPEG-2 video codec system, called theKAIST image computing system (KICS), was developed using multiplemultimedia video processors (MVP, TMS320C80). The number ofcomputations and optimum implementation of the MPEG-2 algorithm wereanalyzed for real-time processing. An MVP simulator was used toperform the timing analysis for the real-time MPEG-2 encoding anddecoding, and it verified the design of the KICS. Task partitioningand mapping of the MPEG-2 algorithm to multiple MVPs were performedbased on load-balancing, minimum data I/O, and the properties of theMVP. The KICS uses five MVPs for MPEG-2 real-time encoding of a mainprofile at the main level whereas it uses three MVPs for real-timedecoding.
