View source for Instruction set

An '''instruction set''', or '''instruction set architecture''' ('''ISA'''), is the part of the computer architecture related to programming, including the native data types, instructions, registers, addressing modes, memory architecture, interrupt and exception handling, and external I/O. 

An ISA includes a specification of the set of opcodes (machine language), and the native commands implemented by a particular processor.

An instruction set is the interface between a computer's [[software]] and its [[Computer hardware|hardware]], and thereby enables the independent development of these two computing realms.
