opkoodi
Opkoodi, or opcode, is the portion of a machine language instruction that specifies the operation the processor should perform. It is used by the instruction decoder to select the appropriate arithmetic, logic, control, or memory operation, which is then carried out in conjunction with operands such as registers or memory addresses.
The opcode forms a core part of an instruction set architecture (ISA). Depending on the architecture, opcodes
In human-readable form, opcodes are represented by mnemonics in assembly language, such as ADD, MOV, LOAD, or
Opkoodi design influences instruction density, decoding speed, and energy use. Differences between architectures—such as fixed-width RISC
