A Detailed Look Inside the Intel ® NetBurst ™ Micro-Architecture of the Intel Pentium ® 4 Processor P age 8 The SSE instructions are useful for 3D geometry, 3D rendering, speech recognition, video encoding and decoding.
A Detailed Look Inside the Intel ® NetBurst ™ Micro-Architecture of the Intel Pentium ® 4 Processor P age 9 Intel ® NetBurst™ Micro-architecture The Pentium ® 4 processor is the first hardware implementation of a new micro-architecture, the Intel NetBurst micro-architecture.
A Detailed Look Inside the Intel ® NetBurst ™ Micro-Architecture of the Intel Pentium ® 4 Processor P age 10 Overview of the Intel ® NetBurst TM Micro-architecture Pipeline The pipeline of the In.
A Detailed Look Inside the Intel ® NetBurst ™ Micro-Architecture of the Intel Pentium ® 4 Processor P age 11 µops called traces, which are stored in the execution trace cache. The execution trace cache stores these µops in the path of program execution flow, where the results of branches in the code are integrated into the same cache line.
A Detailed Look Inside the Intel ® NetBurst ™ Micro-Architecture of the Intel Pentium ® 4 Processor P age 12 Prefetching The Intel NetBurst micro-architecture supports three prefetching mechanisms: § the first is for instructions only § the second is for data only § the third is for code or data.
A Detailed Look Inside the Intel ® NetBurst ™ Micro-Architecture of the Intel Pentium ® 4 Processor P age 13 The Static Predictor . Once the branch instruction is decoded, the direction of the branch (forward or backward) is known.
A Detailed Look Inside the Intel ® NetBurst ™ Micro-Architecture of the Intel Pentium ® 4 Processor P age 14 § selecting IA-32 instructions that can be decoded into less than 4 µ ops and/or have.
A Detailed Look Inside the Intel ® NetBurst ™ Micro-Architecture of the Intel Pentium ® 4 Processor P age 15 Port 3 . Port 3 supports the dispatch of one store address operation per cycle. Thus the total issue bandwidth can range from zero to six µops per cycle.
A Detailed Look Inside the Intel ® NetBurst ™ Micro-Architecture of the Intel Pentium ® 4 Processor P age 16 b) avoiding the need to access off-chip caches, which can increase the realized bandwidth compared to a normal load-miss, which returns data to all cache levels.
A Detailed Look Inside the Intel ® NetBurst ™ Micro-Architecture of the Intel Pentium ® 4 Processor P age 17 branches are resolved. However, speculative loads cannot cause page faults. Reordering loads with respect to each other can prevent a load miss from stalling later loads.
デバイスIntel NetBurstの購入後に（又は購入する前であっても）重要なポイントは、説明書をよく読むことです。その単純な理由はいくつかあります：
Intel NetBurstをまだ購入していないなら、この製品の基本情報を理解する良い機会です。まずは上にある説明書の最初のページをご覧ください。そこにはIntel NetBurstの技術情報の概要が記載されているはずです。デバイスがあなたのニーズを満たすかどうかは、ここで確認しましょう。Intel NetBurstの取扱説明書の次のページをよく読むことにより、製品の全機能やその取り扱いに関する情報を知ることができます。Intel NetBurstで得られた情報は、きっとあなたの購入の決断を手助けしてくれることでしょう。
Intel NetBurstを既にお持ちだが、まだ読んでいない場合は、上記の理由によりそれを行うべきです。そうすることにより機能を適切に使用しているか、又はIntel NetBurstの不適切な取り扱いによりその寿命を短くする危険を犯していないかどうかを知ることができます。
ですが、ユーザガイドが果たす重要な役割の一つは、Intel NetBurstに関する問題の解決を支援することです。そこにはほとんどの場合、トラブルシューティング、すなわちIntel NetBurstデバイスで最もよく起こりうる故障・不良とそれらの対処法についてのアドバイスを見つけることができるはずです。たとえ問題を解決できなかった場合でも、説明書にはカスタマー・サービスセンター又は最寄りのサービスセンターへの問い合わせ先等、次の対処法についての指示があるはずです。
