Intel ADX was first supported in the Broadwell microarchitecture. [ 1 ] [ 2 ] The instruction set extension contains just two new instructions, though MULX from BMI2 is also considered as a part of the large integer arithmetic support.
AMX was introduced by Intel in June 2020 and first supported by Intel with the Sapphire Rapids microarchitecture for Xeon servers, released in January 2023. [3] [4] It introduced 2-dimensional registers called tiles upon which accelerators can perform operations. It is intended as an extensible architecture; the first accelerator implemented is ...
Windows: supported in Windows 7 SP1, Windows Server 2008 R2 SP1, [23] Windows 8, Windows 10. Windows Server 2008 R2 SP1 with Hyper-V requires a hotfix to support AMD AVX (Opteron 6200 and 4200 series) processors, KB2568088; Windows XP and Windows Server 2003 do not support AVX in both kernel drivers and user applications.
These were however documented by Intel only starting with the subsequent P6 (microarchitecture); [6] their more recent formal name is Virtual-8086 Mode Extensions, abbreviated VME [7] (older documentation may use "Virtual 8086 mode enhancements" as the VME acronym expansion). [6] Some later Intel 486 chips also support it.
The XSAVE instruction set extensions are designed to save/restore CPU extended state (typically for the purpose of context switching) in a manner that can be extended to cover new instruction set extensions without the OS context-switching code needing to understand the specifics of the new extensions.
Advanced Vector Extensions (AVX), Gesher New Instructions (GNI), is an advanced version of SSE announced by Intel featuring a widened data path from 128 bits to 256 bits and 3-operand instructions (up from 2). Intel released processors in early 2011 with AVX support. [7] AVX2 is an expansion of the AVX instruction set.
AMD was the first to introduce the instructions that now form Intel's BMI1 as part of its ABM (Advanced Bit Manipulation) instruction set, then later added support for Intel's new BMI2 instructions. AMD today advertises the availability of these features via Intel's BMI1 and BMI2 cpuflags and instructs programmers to target them accordingly.
ADX (file format), a streamed audio format; Authenticated Data Experiment, an early release of Bluesky's decentralized social network protocol; Average directional movement index, a technical indicator of trend strength in prices of a financial instrument such as a stock or bond
