In [[computer science]], an '''instruction''' is a single operation of a [[central processing unit|processor]] defined by an [[instruction set architecture]]. In a broader sense, an "instruction" may be any representation of an element of an executable program, such as a [[bytecode]]. |
|||
==Clubs== |
|||
On traditional architectures, an instruction includes an [[opcode]] specifying the operation to be performed, such as "add contents of memory to register", and zero or more [[operand]] specifiers, which may specify [[processor register|registers]], memory locations, or literal data. The operand specifiers may have [[addressing mode]]s determining their meaning or may be in fixed fields. |

In [[very long instruction word]] (VLIW) architectures, which include many [[microcode]] architectures, multiple simultaneous operations and operands are specified in a single instruction. |
|||

|||
The size or length of an instruction varies widely, from as little as four bits in some [[microcontroller]]s to many hundreds of bits in some VLIW systems. Most modern processors used in [[personal computer]]s, [[mainframe]]s, and [[supercomputer]]s have instruction sizes between 16 and 64 bits. In some architectures, notably most [[Reduced Instruction Set Computer]]s, instructions are a fixed length, typically corresponding with that architecture's [[word (computing)|word size]]. In other architectures, instructions have variable length, typically integral multiples of a [[byte]] or a [[halfword]]. |

|||
The instructions constituting a program are rarely specified using their internal, numeric form; they may be specified by programmers using an [[assembly language]] or, more commonly, may be generated by [[compiler]]s. |
