The microprograms provided by a manufacturer to be used on their microprogrammed computer are generally called "firmware" or "microcode. " Firmware refers to software that is stored in non-volatile memory (such as ROM or EEPROM) and is responsible for controlling the low-level operations of the computer's hardware. Microcode is a specific type of firmware that controls the behavior of the microprocessor or control unit within the computer, specifying the sequence of micro-operations to perform for each machine instruction.
