The control of the central feeding system can basically be divided into two parts: control components and executive components. The control of the central feeding system is the control component, while the arithmetic unit, memory, and peripheral equipment are the execution components relative to the centralized feeding control.
One connection between the centralized feeding control component and the executive component is through the control line. The control component sends various control commands to the execution component through the control line, usually this kind of control command is called a micro command, and the operation performed by the execution component after receiving the micro command is called a micro operation. Another connection between the control part and the execution part is feedback information. The execution component reflects the operation situation to the control component through the feedback line, so that the control component issues new micro-commands according to the status of the execution component, which is also called "status test". Micro-operations are a group of basic operations in the execution component.
Centralized feeding control basically uses feedback signals, and then processes the signals to output a controllable signal. Feedback signal, processing signal, output signal.
