FPGA Interpolators With Reconfigurable and Multifrequency Approximate Computing using HEVC Fractional Pixel

Suma Gurulingaiah Charantimath | Ravi S M

Abstract: Applicable in different fields and markets, low energy high efficiency video coding (HEVC) codecs and their constituting elements have been heavily studied. Fractional pixel interpolation is one of its most costly blocks. In this work, a field programmable gate array implementation of HEVC fractional pixel interpolation, outperforming literature solutions, is proposed. Approximate computing, in conjunction with hardware reconfiguration, guarantees a tunable interpolation system offering energy versus quality tradeoff to further reduce energy.
