指令寄存器：在触发时钟的正沿触发下，寄存器将数据总线送来的指令存入寄存器；
累加器用于存放当前的结果，它也是双目运算的一个数据来源；
算术逻辑运算单元根据输入的8种不同操作码实现相应的加、与、异或、或等8种基本操作运算；
状态控制器实际上就是一个状态机，它是CPU的控制核心，用于产生一系列的控制信号，启动或停止某些部件。CPU何时进行读指令、读写I/O端口、对ROM数据的读取等操作，都是由状态机来控制的；
-Instruction Register: The trigger is edge triggered clock, the register will be sent to the instruction data bus into the register accumulator for storing the current results, it is also a source of data binary operator arithmetic logic operation unit 8 according to the input different realization of corresponding processing operation code, AND, XOR, or 8 kinds of basic operations such as computing state controller is actually a state machine, which is the control of CPU core, used to generate a series of control signals to start or to stop some of the components. CPU when the read instruction, read and write I/O ports, read the data on the ROM and other operations are controlled by the state machine
