  2. Instruction set architecture - Wikipedia

    en.wikipedia.org/wiki/Instruction_set_architecture

    A given instruction set can be implemented in a variety of ways. All ways of implementing a particular instruction set provide the same programming model, and all implementations of that instruction set are able to run the same executables. The various ways of implementing an instruction set give different tradeoffs between cost, performance ...

  3. 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.

  4. Bloom's taxonomy - Wikipedia

    en.wikipedia.org/wiki/Bloom's_taxonomy

    Bloom's taxonomy is a framework for categorizing educational goals, developed by a committee of educators chaired by Benjamin Bloom in 1956. It was first introduced in the publication Taxonomy of Educational Objectives: The Classification of Educational Goals.

  5. Computer architecture - Wikipedia

    en.wikipedia.org/wiki/Computer_architecture

    The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.

  6. 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 ...

  7. Flynn's taxonomy - Wikipedia

    en.wikipedia.org/wiki/Flynn's_taxonomy

    Flynn's taxonomy is a classification of computer architectures, proposed by Michael J. Flynn in 1966 [1] and extended in 1972. [2] The classification system has stuck, and it has been used as a tool in the design of modern processors and their functionalities.

  8. Machine code - Wikipedia

    en.wikipedia.org/wiki/Machine_code

    Every processor or processor family has its own instruction set. Instructions are patterns of bits, digits, or characters that correspond to machine commands. Thus, the instruction set is specific to a class of processors using (mostly) the same architecture. Successor or derivative processor designs often include instructions of a predecessor ...

  9. Addressing mode - Wikipedia

    en.wikipedia.org/wiki/Addressing_mode

    The various addressing modes that are defined in a given instruction set architecture define how the machine language instructions in that architecture identify the operand(s) of each instruction. An addressing mode specifies how to calculate the effective memory address of an operand by using information held in registers and/or constants ...
