目录描述:处理器模块

它与内部存储器（Memory）和输入/输出（I/O）设备合称为电子计算机三大核心部件。 CPU从逻辑上可以划分成3个模块，分别是控制单元、运算单元和存储单元，这三部分由CPU内部总线连接起来。

控制单元是整个CPU的指挥控制中心，由指令寄存器IR(Instruction Register)、指令译码器ID(Instruction Decoder)和操作控制器OC(Operation Controller)等，对协调整个电脑有序工作极为重要。它根据用户预先编好的程序，依次从存储器中取出各条指令，放在指令寄存器IR中，通过指令译码(分析)确定应该进行什么操作，然后通过操作控制器OC，按确定的时序，向相应的部件发出微操作控制信号。操作控制器OC中主要包括节拍脉冲发生器、控制矩阵、时钟脉冲发生器、复位电路和启停电路等控制逻辑。

Directory description: Processor module

It, together with internal Memory (Memory) and input/output (I/O) devices, is called the three core components of electronic computers. The CPU can be logically divided into three modules, namely the control unit, the computing unit and the storage unit, which are connected by the internal bus of the CPU.

The control unit is the command and control center of the whole CPU, consisting of Instruction Register IR(Instruction Register), instruction Decoder ID(Instruction Decoder) and Operation Controller OC(Operation Controller), etc. It is very important to coordinate the whole computer to work in order. According to the user's pre-programmed program, it takes out each instruction from the memory in turn, puts it in the instruction register IR, determines what operation should be carried out through instruction decoding (analysis), and then sends a microoperation control signal to the corresponding component by operating the controller OC, according to the determined timing. The operation controller OC mainly includes the control logic of beat pulse generator, control matrix, clock pulse generator, reset circuit and power off circuit.
