          <datacite:description descriptionType="Other">多くの公開鍵暗号は多ビット整数乗算を必須とするため，乗算器の性能はそれらのためのハードウェアの性能に影響を与える．Wallace tree 乗算器は，ビット数を n とし配線遅延を無視すると，処理時間は log n に比例する．従って例えば，正しく設計するならば 64 ビット乗算器と 128 ビット乗算器との処理時間の差は理論的にはわずかである．本稿は，配線遅延以外の性能が予定通りとなり，ハードウェアの記述が容易な，更にパイプライン化が容易な，任意のビット数の Wallace tree 乗算器の構成法を提案する．</datacite:description>
          <datacite:description descriptionType="Other">Performance of multipliers influences one of hardwares for many public key cryptographies because such cryptographies require many large-bit integer multiplications. It is known that processing time of n bit Wallace tree multiplier is proportional to log n ignoring wiring delay. Therefore, the difference between processing time of 64 bit multiplier and one of 128 bit multiplier is a little in theory when multipliers are correctly designed. This paper proposes a design method of Wallace tree multiplier with arbitrary bit which has easy hardware description and correctness, and can be easily pipelined.</datacite:description>
