MIPS SIMDテクノロジーとBaikal-T1プロセッサー

• アナログ回路の形での実装
  デジタル機器の優位性にもかかわらず、世界と人間の感覚は依然としてアナログのままです。 好むと好まざるとにかかわらず、情報をデジタル形式で「排他的に」処理する場合でも、ADCに入る前にフィルタを設定する必要があります。 同様に、アナログコンポーネントには、積分器、微分器、加算器などを実装できます。 アナログエレクトロニクスの優位性の数十年にわたって、エンジニアはさまざまな問題を解決するために膨大な経験を積んでおり、優れた開発者（デジタルエレクトロニクスでさえ）はこの遺産を考慮に入れています[ D1 ]。

  
  

• マイクロコントローラーソフトウェアの実装
  処理された信号はほとんどなく、数学は複雑ではないか、リソースを必要としませんか？ この場合、ADC、低動作周波数、および省エネオプションを備えた比較的安価なマイクロコントローラーは非常に選択肢です。 必要に応じて、ボトルネックをアセンブラーで記述できます。

  
  

• FPGA実装
  速度、並列処理、スケーリングのソリューションに高い要件がある場合、数学をVerilogまたはVHDLのモジュールとして説明し、処理に必要な周波数で動作できるFPGAを選択します。 ソリューションが非常に成功し、その幅広い複製に意味がある場合-ASIC [ L3 ]の世界へようこそ。

  
  

• システムオンチップの形でのハードウェアとソフトウェアの実装
  システムは複雑すぎて完全にVerilogで記述することはできません。別のロジックを高級言語でプログラミングし、実際にすべてをLinuxから管理しますか？ この場合、ソリューションはSoC（System-on-a-Chip、SoC）です。完成したプロセッサコア（Nios II、MIPSfpgaなど）を取得し、必要な周辺モジュールで重み付けします。トリッキーな数学を実行します。 一部の操作は、プロセッサー命令[ L4 ]として使用可能にできます。 はい、将来、これはASICでも実装できます。

  
  

• デジタル信号プロセッサ（DSP）の使用
  実際、ここでは、プロセッサコア、独自の周辺機器、および高速デジタル信号処理専用のコマンドセットを備えた既製のチップを購入します。 その周りに、決定[ L10 、 L5 ]を構築します。

  
  

• 汎用プロセッサソフトウェアの実装
  各プロセッサメーカーは、特定の数学演算のパフォーマンスを最適化する独自のアーキテクチャソリューションを提供しています。 また、ソフトウェア開発者のタスクは、必要に応じて、メーカーが提供する機能を使用して計算を高速化することです。 これは、以下のMIPSプロセッサで説明するものです。

  
  
• コンピューティングにグラフィックコントローラーを使用する
  現在のリストをより完全にするために、最も複雑でリソースを大量に消費する計算をビデオカード[ L6 、 L7 ]に入れる可能性に言及することを忘れないでください。
