A Detailed Look Inside the Intel ® NetBurst ™ Micro-Architecture of the Intel Pentium ® 4 Processor P age 5 About this Document The Intel ® NetBurst ™ micro-architecture is the foundation for the Intel ® Pentium ® 4 processor.
A Detailed Look Inside the Intel ® NetBurst ™ Micro-Architecture of the Intel Pentium ® 4 Processor P age 6 Introduction The Intel ® Pentium ® 4 processor, utilizing the Intel ® NetBurst TM mic.
A Detailed Look Inside the Intel ® NetBurst ™ Micro-Architecture of the Intel Pentium ® 4 Processor P age 7 computations to operate on packed double-precision floating-point data elements and 128-bit packed integers.
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.
Un punto importante, dopo l’acquisto del dispositivo (o anche prima di acquisto) è quello di leggere il manuale. Dobbiamo farlo per diversi motivi semplici:
Se non hai ancora comprato il Intel NetBurst è un buon momento per familiarizzare con i dati di base del prodotto. Prime consultare le pagine iniziali del manuale d’uso, che si trova al di sopra. Dovresti trovare lì i dati tecnici più importanti del Intel NetBurst - in questo modo è possibile verificare se l’apparecchio soddisfa le tue esigenze. Esplorando le pagine segenti del manuali d’uso Intel NetBurst imparerai tutte le caratteristiche del prodotto e le informazioni sul suo funzionamento. Le informazioni sul Intel NetBurst ti aiuteranno sicuramente a prendere una decisione relativa all’acquisto.
In una situazione in cui hai già il Intel NetBurst, ma non hai ancora letto il manuale d’uso, dovresti farlo per le ragioni sopra descritte. Saprai quindi se hai correttamente usato le funzioni disponibili, e se hai commesso errori che possono ridurre la durata di vita del Intel NetBurst.
Tuttavia, uno dei ruoli più importanti per l’utente svolti dal manuale d’uso è quello di aiutare a risolvere i problemi con il Intel NetBurst. Quasi sempre, ci troverai Troubleshooting, cioè i guasti più frequenti e malfunzionamenti del dispositivo Intel NetBurst insieme con le istruzioni su come risolverli. Anche se non si riesci a risolvere il problema, il manuale d’uso ti mostrerà il percorso di ulteriori procedimenti – il contatto con il centro servizio clienti o il servizio più vicino.
