ISA
Instruction Set Architecture
ISA is the acronym for Instruction Set Architecture.
What is Instruction Set Architecture?
A standardized interface between the software and the hardware of a computer system, and it provides the foundation for operating systems and applications to run on a wide variety of hardware platforms. By specifying the ISA, hardware vendors are able to build compatible devices, and software vendors can create software that can run on any compatible hardware platform.
In the context of open systems, an open ISA refers to a computer architecture that is publicly specified and standardized, allowing for interoperability and collaboration between hardware and software vendors. Open ISA specifications are typically developed by open standards organizations, and the goal is to ensure that the ISA remains freely available and accessible for anyone to implement and use. Examples of open ISA architectures include the RISC-V ISA and the OpenPOWER ISA.
