 | | An instruction set, or instruction set architecture (ISA), describes the aspects of a computer architecture visible to a programmer, including the native datatypes, instructions, registers, addressing modes, memory architecture, interrupt and exception handling, and external I/O (if any). |
 | | An ISA is a specification of the set of all binary codes (opcodes) that are the native form of commands implemented by a particular CPU design. |
 | | "Instruction set architecture" is sometimes used to distinguish this set of characteristics from the microarchitecture, which is the set of processor design techniques used to implement the instruction set (including microcode, pipelining, cache systems, and so forth). |
