    Instruction set architecture - Wikipedia

    https://en.wikipedia.org/wiki/Instruction_set_architecture

    In computer science, an instruction set architecture (ISA), also called computer architecture, is an abstract model of a computer. A device that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation. In general, an ISA defines the

    An ISA may be classified in a number of different ways. A common classification is by architectural complexity. A complex instruction set computer (CISC) has many specialized instructions, some of which may only be rarely used in practical programs. A

    Machine language is built up from discrete statements or instructions. On the processing architecture, a given instruction may specify:
    • opcode (the instruction to be performed) e.g. add, copy, test
    • any explicit operands:

    09/11/2008 · An instruction set, or instruction set architecture (ISA), is a list of all the commands (instructions), with all their variations, that a processor can execute. Instructions include: Arithmetic such as add and subtract; Logic instructions such as and, or, and not; Data instructions such as move, input, output, load, and store

    https://it.wikipedia.org/wiki/Instruction_set

    L'instruction set, in informatica ed elettronica, è l'insieme di istruzioni macchina che descrive quegli aspetti, visibili a basso livello al programmatore, dell'architettura di un calcolatore, definita in inglese come instruction set architecture o in acronimo ISA. L'espressione è a volte usata anche per distinguere l'insieme suddetto di caratteristiche dalla microarchitettura che è …

    29/12/2021 · One Instruction Set. The so called Ultimate Reduced Instruction Set Computer (URISC) or One Instruction Set Computer (OISC) is programmed by only one instruction. This instruction must make it possible to decide, to move data, to calculate, and to jump to different targets in the instruction stream. This is only possible with a complex instruction.

    What is instruction set architecture (ISA)?
    An instruction set architecture (ISA) is an abstract model of a computer. It is also referred to as architecture or computer architecture.
    en.wikipedia.org/wiki/Instruction_set_architecture
    What is an instruction set?
    An instruction set is the part of the computer architecture related to programming. An ISA includes a specification set of opcodes ( machine language ), which are the native commands implemented in a particular central processing unit design. Computers with different microarchitectures can share a common instruction set.
    simple.wikipedia.org/wiki/Instruction_set
    What is the difference between a computer architecture and instruction set?
    This is actually a simplification as computer architecture often has a few more or less "natural" datasizes in the instruction set, but the hardware implementation of these may be very different.
    en.wikipedia.org/wiki/Comparison_of_instruction_set_arc…
    What makes ISAS the most fundamental architecture in computing?
    The binary compatibility that they provide make ISAs one of the most fundamental abstractions in computing . An instruction set architecture is distinguished from a microarchitecture, which is the set of processor design techniques used, in a particular processor, to implement the instruction set.

    https://docs.google.com/presentation/d...

    Computer program consists of a sequence of instructions; instruction = verb + operand(s) stored in memory as 1’s and 0’s; called machine code. Instructions are fetched from memory; The program counter (PC) holds the memory address of the next instruction (or operand). The instruction is stored internal to the CPU in the instruction register (IR).

    Reduced Instruction Set Computer ist eine Designphilosophie für Computerprozessoren. Der Begriff wurde 1980 von David A. Patterson und Carlo H. Séquin geprägt. Das Designziel war der Verzicht auf einen komplexen, für die Assemblerprogrammierung komfortablen Befehlssatz hin zu einfach zu dekodierenden und schnell auszuführenden Befehlen. Dies ermöglichte zudem …
