    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.
