Define Instruction Set Architecture. What are the main objectives of ISA in computer systems.

Instruction Set Architecture (ISA):

An instruction set is the interface between a computer's software and its hardware, and thereby enables the independent development of these two computing realms. ISA is the set of basic instructions that a processor understands.

ISA includes functional definition of operations, modes, and storage locations supported by hardware and precise description of how to invoke, and access them.

The instruction set or the instruction set architecture (ISA) is the set of basic instructions that a processor understands. The instruction set is a portion of what makes up an architecture.


Two initial types of instruction set architecture are CISC (Complex Instruction Set Computer) and RISC (Reduced Instruction Set Computer).
