  2. x86 instruction listings - Wikipedia

    en.wikipedia.org/wiki/X86_instruction_listings

    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 ...

  3. Instruction set architecture - Wikipedia

    en.wikipedia.org/wiki/Instruction_set_architecture

    In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. [1] A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation of that ISA.

  4. Comparison of instruction set architectures - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_instruction...

    An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.

  5. RISC-V instruction listings - Wikipedia

    en.wikipedia.org/wiki/RISC-V_instruction_listings

    The RISC-V instruction set refers to the set of instructions that RISC-V compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor.

  6. Machine code - Wikipedia

    en.wikipedia.org/wiki/Machine_code

    In computer programming, machine code is computer code consisting of machine language instructions, which are used to control a computer's central processing unit (CPU). For conventional binary computers , machine code is the binary representation of a computer program which is actually read and interpreted by the computer.

  7. Minimal instruction set computer - Wikipedia

    en.wikipedia.org/wiki/Minimal_instruction_set...

    A MISC CPU cannot have one instruction as that is a one instruction set computer. [4] The implemented CPU instructions should by default not support a wide set of inputs, so this typically means an 8-bit or 16-bit CPU. If a CPU has an NX bit, it is more likely to be viewed as being a complex instruction set computer (CISC) or reduced ...

  9. x86 assembly language - Wikipedia

    en.wikipedia.org/wiki/X86_assembly_language

    x86 assembly language is a family of low-level programming languages that are used to produce object code for the x86 class of processors. These languages provide backward compatibility with CPUs dating back to the Intel 8008 microprocessor, introduced in April 1972.
