Intel® 64 and IA-32 Architectures Optimization Reference Manual

INTRODUCTION• Chapter 10: Power Optimization for Mobile Usages — This chapter providesbackground on power saving techniques in mobile processors and makes recommendationsthat developers can leverage to provide longer battery life.• Appendix A: Application Performance Tools — Introduces tools for analyzingand enhancing application performance without having to write assembly code.• Appendix B: Intel Pentium 4 Processor Performance Metrics — Providesinformation that can be gathered using Pentium 4 processor’s performancemonitoring events. These performance metrics can help programmers determinehow effectively an application is using the features of the Intel NetBurst microarchitecture.• Appendix C: IA-32 Instruction Latency and Throughput — Provides latencyand throughput data for the IA-32 instructions. Instruction timing data specific tothe Pentium 4 and Pentium M processors are provided.• Appendix D: Stack Alignment — Describes stack alignment conventions andtechniques to optimize performance of accessing stack-based data.• Appendix E: The Mathematics of Prefetch Scheduling Distance —Discusses the optimum spacing to insert PREFETCH instructions and presents amathematical model for determining the prefetch scheduling distance (PSD) foryour application.• Appendix F: Summary of Rules and Suggestions — Summarizes the rulesand tuning suggestions referenced in the manual.1.3 RELATED INFORMATIONFor more information on the Intel ® architecture, techniques, and the processorarchitecture terminology, the following are of particular interest:• Intel ® 64 and IA-32 Architectures Software Developer’s Manual (in five volumes)http://developer.intel.com/products/processor/manuals/index.htm• Intel ® Processor Identification with the CPUID Instruction, AP-485http://www.intel.com/support/processors/sb/cs-009861.htm• Developing Multi-threaded Applications: A Platform Consistent Approachhttp://cachewww.intel.com/cd/00/00/05/15/51534_developing_multithreaded_applications.pdf• Intel ® C++ Compiler documentation and online helphttp://www.intel.com/cd/software/products/asmo-na/eng/index.htm• Intel ® Fortran Compiler documentation and online helphttp://www.intel.com/cd/software/products/asmo-na/eng/index.htm• Intel ® VTune Performance Analyzer documentation and online helphttp://www.intel.com/cd/software/products/asmo-na/eng/index.htm1-3
