Microoperations are non-decomposable operations that always require corresponding control signals (known as microoperational control signals or microoperational commands). A digital computer can be basically divided into two parts – the control part and the executive part. The controller is the control component, and the computer, memory, peripheral equipment is the executive component relative to the controller. One connection between the control and the executive is through the control line. The control unit issues various control commands to the executive unit through the control line. Usually, such control commands are called microcommands, and the operations performed by the executive unit after accepting the microcommands are called microoperations. Another connection between the control and the executive is feedback. The executive unit reflects the operation situation to the control unit through the feedback line, so that the control unit can issue new microcommands according to the state of the executive unit, which is also called “state testing”. Microoperations are a set of basic operations in an executive unit. Because of the structure of the data path, microoperations can be divided into
