| Abstract |
携帯器器および家電のLSI部を設計する際は, 設計者が音声, 画像をはじめ器機出力の品質および仕様を考慮して, ハードウェアおよびソフトウェアの設計最適化を行っている.我々はワード幅が出力品質にもたらす影響に着目し, 出力品質駆動設計(output-quality-driven)最適手法を提案している.本論文では, 出力品質の最適化を考慮した動作記述の作成とハードウェア設計手法について提案する.
D...esigners of mobile or household appliances often optimize both hardware and software in order to make products which complies to a designated output quality specification. Noticing that word-width can affect the output quality, we come into a novel optimization method that we call ″output quality driven″optimization method. In this paper, we will overview our recent reseaches on system description and hardware design deploying the aforementioned optimization method.show more
