Analysis of Memory Access Optimization for Motion Compensation Frames in MPEG-4

Haitham Habli, Johan Ersfolk, Johan Lilius, Analysis of Memory Access Optimization for Motion Compensation Frames in MPEG-4. In: Jari Nurmi, Jarmo Takala, Olli Vainio (Eds.), 2009 International Symposium on System-on-Chip Proceedings, 114–117, IEEE, 2009.

Abstract:

One of the big sources for energy consumption in modern video coding
algorithms is the access to the reference frame, that is required in
the motion compensation calculations. It is challenging to decrease
this energy consumption because of the irregularity of the access. In
this paper we evaluate an approach in which we presort the motion vectors
so as to increase the locality of the accesses.
