Hardware video accelerators are used on mobile devices to provide support for energy efficient real time High Definition (HD) video decoding. Recently, the rise of multi-core architectures on those devices increased their performances and make real time HD video decoding possible using parallel processing on the GPP cores only. What is even more interesting to know is the level of energy efficiency this kind of multi-core General Purpose Processor (GPP) can achieve as compared to hardware video accelerators.
