An architecture for affine motion estimation in real-time video coding

With the ever-increasing demand for real-time video applications, a dedicated and efficient architecture for motion estimation has become a necessity., In this paper, we present an architecture for affine motion estimation which meets the real-time application requirements. The architecture employs a modular memory structure for efficient pipelined parallel implementation of affine motion estimation using the one-dimensional hierarchical search (1DHS) algorithm. Implementation results in terms. of the number of clock cycles and PSNR values demonstrate the efficiency of the proposed architecture.
