Reducing Data-Memory Footprint of Multimedia Applications by Delay Redistribution
2007
Proceedings - Design Automation Conference
Preserved Fulltext
We show that this delay redistribution technique can signficantly reduce (up to 70%) the total on-chip memory required. ...
In this paper, instead of associating the playout delay solely with the output device, we propose to redistribute this delay among all the processing elements running the various tasks of the multimedia ...
The execution of some tasks of multimedia applications (e.g. VLD in MPEG-2) show high data-dependent variability. ...
