The products described in this document may contain design defects or errors known as errata which may cause the product to deviate from published specifications. Current characterized errata are available on request. Intel® AES-NI requires a computer system with an AES-NI enabled processor, as well as non-Intel software to execute the instructions in the correct sequence. AES-NI is available on select Intel® processors. For availability, consult your reseller or system manufacturer. For more in- formation, see http://software.intel.com/en-us/articles/intel-advanced-encryption-standard-instructions-aes-ni/. Intel® Hyper-Threading Technology (Intel® HT Technology) is available on select Intel® CoreTM processors. Requires an Intel® HT Technology- enabled system. Consult your PC manufacturer. Performance will vary depending on the specific hardware and software used. For more infor- mation including details on which processors support HT Technology, visit http://www.intel.com/info/hyperthreading. Intel® Virtualization Technology requires a computer system with an enabled Intel® processor, BIOS, and virtual machine monitor (VMM). Func- tionality, performance or other benefits will vary depending on hardware and software configurations. Software applications may not be com- patible with all operating systems. Consult your PC manufacturer. For more information, visit http://www.intel.com/go/virtualization. Intel® 64 architecture Requires a system with a 64-bit enabled processor, chipset, BIOS and software. Performance will vary depending on the specific hardware and software you use. Consult your PC manufacturer for more information. For more information, visit http://www.in- tel.com/info/em64t. Enabling Execute Disable Bit functionality requires a PC with a processor with Execute Disable Bit capability and a supporting operating system. Check with your PC manufacturer on whether your system delivers Execute Disable Bit functionality.

ABOUT THIS MANUAL The Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volume 1: Basic Architecture (order number 253665) is part of a set that describes the architecture and programming environment of Intel® 64 and IA-32 architecture processors. Other volumes in this set are: • The Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volumes 2A, 2B & 2C: Instruction Set Reference (order numbers 253666, 253667 and 326018). • The Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volumes 3A, 3B & 3C: System Programming Guide (order numbers 253668, 253669 and 326019). The Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volume 1, describes the basic architecture and programming environment of Intel 64 and IA-32 processors. The Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volumes 2A, 2B & 2C, describe the instruction set of the processor and the opcode structure. These volumes apply to application programmers and to programmers who write operating systems or executives. The Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volumes 3A, 3B & 3C, describe the operating-system support environment of Intel 64 and IA-32 processors. These volumes target operating-system and BIOS designers. In addition, the Intel® 64 and IA-32 Architectures Software Developer’s Manual, Volume 3B, addresses the programming environment for classes of software that host operating systems. 1.1 INTEL® 64 AND IA-32 PROCESSORS COVERED IN THIS MANUAL This manual set includes information pertaining primarily to the most recent Intel 64 and IA-32 processors, which include: • Pentium® processors • P6 family processors • Pentium® 4 processors • Pentium® M processors • Intel® Xeon® processors • Pentium® D processors • Pentium® processor Extreme Editions • 64-bit Intel® Xeon® processors • Intel® CoreTM Duo processor • Intel® CoreTM Solo processor • Dual-Core Intel® Xeon® processor LV • Intel® CoreTM2 Duo processor • Intel® CoreTM2 Quad processor Q6000 series • Intel® Xeon® processor 3000, 3200 series • Intel® Xeon® processor 5000 series • Intel® Xeon® processor 5100, 5300 series • Intel® CoreTM2 Extreme processor X7000 and X6800 series • Intel® CoreTM2 Extreme processor QX6000 series • Intel® Xeon® processor 7100 series • Intel® Pentium® Dual-Core processor • Intel® Xeon® processor 7200, 7300 series • Intel® Xeon® processor 5200, 5400, 7400 series • Intel® CoreTM2 Extreme processor QX9000 and X9000 series • Intel® CoreTM2 Quad processor Q9000 series • Intel® CoreTM2 Duo processor E8000, T9000 series • Intel® AtomTM processor family • Intel® CoreTM i7 processor • Intel® CoreTM i5 processor • Intel® Xeon® processor E7-8800/4800/2800 product families • Intel® Xeon® processor E5 family • Intel® Xeon® processor E3-1200 family • Intel® CoreTM i7-3930K processor • 2nd generation Intel® CoreTM i7-2xxx, Intel® CoreTM i5-2xxx, Intel® CoreTM i3-2xxx processor series • Intel® Xeon® processor E3-1200 v2 product family • 3rd generation Intel® CoreTM processors • Next generation Intel® CoreTM processors P6 family processors are IA-32 processors based on the P6 family microarchitecture.
