CPU

Memory can refer to main memory, cache or register stack, etc. used to hold an instruction currently being executed. When an instruction is executed, it is first fetched from memory into the data register (DR) and then transferred to IR. Instructions are divided into opcode and address code fields, consisting of binary digits. In order to execute any given instruction, the opcode must be tested in order to identify the required operation. The instruction decoder does the job. The output of the opcode field in the instruction register is the input to the instruction decoder. Once the opcode is decoded, a specific signal for a specific operation can be sent to the operation controller.

Program Counter: A counter that indicates the address of the next instruction to be executed in the program, also known as the instruction counter. It has the functions of an instruction address register and a counter. When an instruction is executed, the program counter is used as an instruction address register, and its content must have been changed to the address of the next instruction, so that the program can continue to run.

Motor controllers can be divided into DC motor controllers and AC motor controllers according to their current forms. Motors can be divided into DC motors, brushless DC motors and stepper motors according to their driving methods. The drive can also be divided into a unipolar stepper motor drive circuit and a bipolar stepper motor drive circuit.
