1、指令控制器

指令控制器是控制器中相当重要的局部，它要完成取指令、分析指令等操作，然后交给执行单元〔ALU或FPU〕来执行，同时还要形成下一条指令的地址。

2、时序控制器

时序控制器的作用是为每条指令按时间顺序提供控制信号。时序控制器包括时钟发生器和倍频定义单元，其中时钟发生器由石英晶体振荡器发出非常稳定的脉冲信号，就是CPU的主频；而倍频定义单元那么定义了CPU主频是存储器频率〔总线频率〕的几倍。

3、总线控制器

总线控制器主要用于控制CPU的内外部总线，包括地址总线、数据总线、控制总线等等。

1, command controller

The instruction controller is a very important part of the controller, which needs to complete operations such as fetching instructions, analyzing instructions, and then handing them to the execution unit (ALU or FPU) for execution, and at the same time forming the address of the next instruction.

2. Timing controller

The function of a timing controller is to provide a control signal for each instruction in chronological order. The timing controller includes a clock generator and a frequency doubling definition unit, wherein the clock generator sends a very stable pulse signal from the quartz crystal oscillator, which is the main frequency of the CPU; The frequency doubling definition unit then defines that the CPU frequency is several times the memory frequency (bus frequency).

3. Bus controller

The bus controller is mainly used to control the internal and external buses of the CPU, including the address bus, data bus, control bus and so on.
