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. The ISA provides the only way through which a user is able ...

In computer science, an instruction set architecture, 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, is called an implementation. In general, an ISA defines the supported instructions, data types, registers, the hardware support for managing main memory, …

The instruction set architecture ( ISA ) is a part of the processor architecture. The ISA is defined as entire group of commands implemented into the processor’s microarchitecture. The ISA works an interface between the hardware and software. The ISA defines the set of commands that the processor can perform to execute the program instructions.

In computer science, an instruction set architecture ( ISA) is an abstract model of a computer. It is also referred to as architecture or computer architecture. A realization of an ISA, such as a central processing unit (CPU), is called an implementation .
