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.
An important point after buying a device Intel NetBurst (or even before the purchase) is to read its user manual. We should do this for several simple reasons:
If you have not bought Intel NetBurst yet, this is a good time to familiarize yourself with the basic data on the product. First of all view first pages of the manual, you can find above. You should find there the most important technical data Intel NetBurst - thus you can check whether the hardware meets your expectations. When delving into next pages of the user manual, Intel NetBurst you will learn all the available features of the product, as well as information on its operation. The information that you get Intel NetBurst will certainly help you make a decision on the purchase.
If you already are a holder of Intel NetBurst, but have not read the manual yet, you should do it for the reasons described above. You will learn then if you properly used the available features, and whether you have not made any mistakes, which can shorten the lifetime Intel NetBurst.
However, one of the most important roles played by the user manual is to help in solving problems with Intel NetBurst. Almost always you will find there Troubleshooting, which are the most frequently occurring failures and malfunctions of the device Intel NetBurst along with tips on how to solve them. Even if you fail to solve the problem, the manual will show you a further procedure – contact to the customer service center or the nearest service center
