Low-energy motion estimation memory system with dynamic management

Low-Power Motion Estimation Processor with 3D Stacked Memory

Motion estimation (ME) is a key encoding component of almost all modern video coding standards. ME contributes significantly to video coding efficiency, but, it also consumes the most power of any component in a video encoder. In this paper, an ME processor with 3D stacked memory architecture is proposed to reduce memory and core power consumption. First, a memory die is designed and stacked wi...

Low omplexity motion estimation for long term memory motion ompensation

Dynamic Visual Motion Estimation

Visual motion is the projection of scene movements on a visual sensor. It is a rich source of information for the analysis of a visual scene. Especially for dynamic vision systems the estimation of visual motion is important because it allows to deduce the motion of objects as well as the self-motion of the system relative to the environment. Therefore, visual motion serves as a basic informati...

Low complexity motion estimation algorithm by multiresolution search for long-term memory motion compensation

We propose a new low complexity motion estimation (ME) algorithm using multiresolution motion search for long term memory motion compensation (LTMC, [1]). While multiresolution motion search has been used for standard single-frame motion compensation, here we introduce several novel techniques to exploit it efficiently in the context of LTMC. The proposed algorithm computes a coarse motion vect...

Low - Energy Asynchronous Memory

We introduce the concept of energy per operation as a measure of performance of an asynchronous circuit. We show how to model energy consumption based on the high-level language speciication. This model is independent of voltage and timing considerations. We apply this model to memory design. We show rst how to dimension a memory array, and how to break up this memory array into smaller arrays ...
