Abstract :
In the latest draft video compression standard, HEVC, a new 8-tap MC interpolation filter is adopted. For this component, we propose an efficient VLSI design which is composed of a reconfigurable filter, an optimized pipeline engine organization, and a filter reuse scheme. This results in 30% area saving from a non-optimized design. The proposed implementation supports a maximal throughput of QFHD@60fps. Our results also demonstrate the implementation cost of a well optimized HEVC interpolation component can be comparable to that of H.264, despite of the enhanced coding performance.
