YOKOGAWA CP461-50 处理器模块

我们都知道CPU的根本任务就是执行指令，对计算机来说最终都是一串由“0”和“1”组成的序列。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：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。

We all know that the fundamental task of a CPU is to execute instructions, and for a computer, it is ultimately a sequence composed of "0" and "1". The CPU can be logically divided into three modules, namely control unit, computing unit, and storage unit, which are connected by the internal bus of the CPU. Control unit: The control unit is the command and control center of the entire CPU. The instruction register (IR), Instruction Decoder ID (InstrucTI on Decoder) and Operation Controller OC (OperaTI on Controller) are very important for coordinating the orderly work of the entire computer. According to the user's pre programmed program, it takes out each instruction from the memory in turn, places it in the instruction register IR, determines what operation should be carried out through instruction decoding (analysis), and then sends micro operation control signals to the corresponding parts according to the determined timing by operating the controller OC. The operating controller OC mainly includes control logic such as beat pulse generator, control matrix, clock pulse generator, reset circuit, and start stop circuit.
