          <datacite:description descriptionType="Other">ステレオ距離画像生成処理に対し，VLIW型メディアプロセッサFR-V，およびメディア演算命令を塔載した汎用マイクロプロセッサを用い，処理速度および消費電力の観点から評価，比較を行った．いずれのプロセッサでもメディア演算命令を用いることで飛躍的に処理速度が向上したが，特にFR550は処理速度，消費電力の両点において最も優れた結果が得られ，モバイル製品等への組込み用プロセッサとして適していることを示す．また，FR550に絶対差の総和を求める拡張命令の存在を仮定すると，サイクル数を約28%削減でき，さらに命令並列度の改善を施すことにより，これを約36%まで引き上げることができることを示す．</datacite:description>
          <datacite:description descriptionType="Other">This paper describes an evaluation of media-enhanced superscalar processors and FR-V: a media-enhanced VLIW processor, using an application program for stereo depth extraction. We evaluate the delay and the power consumption of each processor, and the result shows that FR550 is most superior to the others in energy-delay product. Also it is shown that 28% of the execution cycles can be eliminated by the additional instruction which calculates the sum of absolute differences directly. Furthermore, increasing the available number of media-operations in a VLIW improves the performance by 36%.</datacite:description>
