In the x86 assembly language, the TEST instruction performs a bitwise AND on two operands. The flags SF, ZF, PF are modified while the result of the AND is discarded. The OF and CF flags are set to 0, while AF flag is undefined. There are 9 different opcodes for the TEST instruction depending on the type and size of the operands. It can compare ...
Linux becomes the first OS kernel to fully support x86-64 (on a simulator, as no x86-64 processors had been released yet). [23] 2001 Microsoft releases Windows XP 64-Bit Edition for the Itanium's IA-64 architecture; it could run 32-bit applications through an execution layer. [citation needed] 2003
AMD Opteron, the first CPU to introduce the x86-64 extensions in April 2003 The five-volume set of the x86-64 Architecture Programmer's Manual, as published and distributed by AMD in 2002. x86-64 (also known as x64, x86_64, AMD64, and Intel 64) [note 1] is a 64-bit extension of the x86 instruction set architecture first announced in
The x86 instruction set refers to the set of instructions that x86-compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor. The x86 instruction set has been extended several times, introducing wider registers and datatypes as well as new ...
In April 2003, AMD released the first x86 processor with 64-bit general-purpose registers, the Opteron, capable of addressing much more than 4 GB of virtual memory using the new x86-64 extension (also known as AMD64 or x64). The 64-bit extensions to the x86 architecture were enabled only in the newly introduced long mode, therefore 32-bit and ...
SSE2 is an extension of the IA-32 architecture, based on the x86 instruction set. Therefore, only x86 processors can include SSE2. The AMD64 architecture supports the IA-32 as a compatibility mode and includes the SSE2 in its specification. [1] [2] It also doubles the number of XMM registers, allowing for better performance.
Minimum configuration of 1GB RAM and 100 megabytes of free hard disk space, 1.80 GHz or faster 2 cores and x86/x64 compatible architectures. Also compatible with Windows Surface Pro and Surface Pro 2 tablets. Note - AOL Tech Fortress is not supported on Mac devices or operating systems.
The Thread Information Block (TIB) or Thread Environment Block (TEB) is a data structure in Win32 on x86 that stores information about the currently running thread. It descended from, and is backward-compatible on 32-bit systems with, a similar structure in OS/2. [1] The TIB is officially undocumented for Windows 9x.
