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.

Jan 21, 2022 · In this article, we look at what an Instruction Set Architecture (ISA) is and what is the difference between an 'ISA' and Microarchitecture. An ISA is defined as the design of a computer from the Programmer's Perspective.

CI 50 (Martin/Roth): Instruction Set Architectures 4 What Is An ISA? ¥ISA (instruction set architecture) ¥A well-define hardware/software interface ¥The ÒcontractÓ between software and hardware ¥Functional definition of operations, modes, and storage locations supported by hardware ¥Precise description of how to invoke, and access them

An Instruction Set Architecture (ISA) defines the communication rules between the hardware and software of the computer. The ISA is a design principle (conceptual) and not stored in a computer’s memory.

An Instruction Set Architecture (ISA) is part of the abstract model of a computer that defines how the CPU is instructed and controlled by the software. The ISA acts as an interface between the hardware and the software.

The objectives of this module is to understand the importance of the instruction set architecture, discuss the features that need to be considered when designing the instruction set architecture of a machine and look at an example ISA, MIPS.

An Instruction Set Architecture (ISA) is part of the abstract model of a computer that defines how the CPU is controlled by the software. The ISA acts as an interface between the hardware and the software, specifying both what the processor is capable of doing as well as how it gets done.

Jan 11, 2022 · An instruction set architecture or ISA is one of the three major components of a computer architecture alongside microarchitecture and systems design. It specifically corresponds to a conceptual or abstract model of a computer.

Apr 22, 2025 · At its core, the Instruction Set Architecture (ISA) is the abstract model of a computer that defines how software controls the hardware.

Instruction set architecture is a set of processor design technique used to implement the instruction workflow on hardware ISA basically tells how your processor is going to process your program instruction.
