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 ...
Bit manipulation instructions sets (BMI sets) are extensions to the x86 instruction set architecture for microprocessors from Intel and AMD. The purpose of these instruction sets is to improve the speed of bit manipulation. All the instructions in these sets are non-SIMD and operate only on general-purpose registers.
The XOP (eXtended Operations [1]) instruction set, announced by AMD on May 1, 2009, is an extension to the 128-bit SSE core instructions in the x86 and AMD64 instruction set for the Bulldozer processor core, which was released on October 12, 2011. [2] However AMD removed support for XOP from Zen (microarchitecture) onward. [3]
APX is a new extension. It is not focused on vector computation, but provides RISC-like extensions to the x86-64 architecture by doubling the number of general-purpose registers to 32 and introducing three-operand instruction formats. AVX is only tangentially affected as APX introduces extended operands. [43] [44]
In computing, Streaming SIMD Extensions (SSE) is a single instruction, multiple data instruction set extension to the x86 architecture, designed by Intel and introduced in 1999 in its Pentium III series of central processing units (CPUs) shortly after the appearance of Advanced Micro Devices (AMD's) 3DNow!.
Instructions that have been added to the x86 instruction set in order to assist efficient calculation of cryptographic primitives, such as e.g. AES encryption, SHA hash calculation and random number generation.
Norton Guides manual and disks. Norton Guides were a product family sold by Peter Norton Computing.The guides were written in 1985 by Warren Woodford for the x86 Assembly Language, C, BASIC, and Forth languages and made available to DOS users via a terminate-and-stay-resident (TSR) program that integrated with programming language editors on IBM PC type computers.
Ralf Brown's Interrupt List (aka RBIL, x86 Interrupt List, MS-DOS Interrupt List or INTER) is a comprehensive list of interrupts, calls, hooks, interfaces, data structures, CMOS settings, memory and port addresses, as well as processor opcodes for x86 machines from the 1981 IBM PC up to 2000 (including many clones), [1] [2] [nb 1] most of it still applying to IBM PC compatibles today.
