APPLICATION NOTE

MPEG2 Main Profile Video Decoding on ST100

By Maurizio COLOMBO

ABSTRACT

This document reports the results of the porting of a MainProfile@MainLevel MPEG-2 decoder on ST120.

This is the standard notably used for DVD.

CONCLUSION

The optimized application needs 228.4 MCycles/s to decode 25 PAL frames/s in the case of M=3, N=12,

bitrate=15 Mbps. In this evaluation we assume that all the data are into the XY internal memories (ideal

DMA).
