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.
Intel EP80579, a system-on-a-chip based on the 90 nm Dothan Pentium M, aimed at embedded applications. [62] Possibly Tolapai Spring, Arizona, USA. 2007 Tonga: CPU Pentium II Mobile processor, 250 nm. Probably the island nation of Tonga. 1998 Topcliff Chipset Intel EG20T PCH, for use with Atom E600 series (Tunnel Creek) processors. Reference ...

The default OperandSize and AddressSize to use for each instruction is given by the D bit of the segment descriptor of the current code segment - D=0 makes both 16-bit, D=1 makes both 32-bit. Additionally, they can be overridden on a per-instruction basis with two new instruction prefixes that were introduced in the 80386:
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
The GNU Assembler (GAS) inline assembly functions support these instructions (accessible via GCC), as do Intel primitives and the Intel inline assembler (closely compatible to GAS, although more general in its handling of local references within inline code). GAS supports AVX starting with binutils version 2.19.
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. [2]
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 ...
