In computer architecture, microcode is a layer of low-level control data or instructions used to implement a processor's instruction set architecture or internal control sequences. It consists of hardware-level operations that carry out higher-level machine code instructions or direct internal sequencing in many digital components. In many modern Intel and AMD general-purpose processors, common instructions are decoded directly into internal micro-operations, while microcode is used mainly for more complex instructions, special cases, and processor updates.
