Microprogramming is the concept of microprogramming was developed by Maurice Wilkes in 1951, by means of diode matrices for the memory element. A microprogram consists of a sequence of micro-instructions in a microprogramming.
Microprogramming (i.e. writing microcode) is a way that can be employed to execute machine instructions in a CPU fairly easily, often using less hardware than with other methods. It is a set of very full and rudimentary lowest-level routines which controls and sequences the actions needed to carry out (perform) particular instructions, at times also to decode (interpret) them. A machine instruction implemented by a series of microinstructions is therefore loosely similar to how an interpreter implements a high-level language statement by means of a series of machine instructions.
