An instruction set architecture (ISA) is one of the most important interfaces in a computer system because it divides soft-ware from hardware. Most widely used ISAs were developed decades ago and are propriet-ary. This may make sense because hardware implementations were and are mostly propri-etary and most software was proprietary when

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.

The core LE1 CPU is a configurable, 8-stage pipeline VLIW engine with a proprietary Instruction Set Architecture (ISA) supporting both partial and full predication and pipelined, multi-input, multi-output (MIMO) instruction extensions.

Instruction Sets “Instruction set architecture is the structure of a computer that a machine language programmer (or a compiler) must understand to write a correct (timing independent) program for that machine” –IBM introducing 360 (1964) an instruction set specifies a processor’s functionality • what operations it supports

MOST WIDELY USED INSTRUCTION SET ARCHITECTURES (ISAS) ARE PROPRIETARY, WHILE MUCH SOFTWARE INNOVATION IS FACILITATED BY BEING OPEN. MIGHT HARDWARE INNOVATION ALSO BE ACCELERATED BY ISAS BEING OPEN?
