磁阻开关电机控制器

电机控制器 品质保证

控制器分组合逻辑控制器和微程序控制器,两种控制器各有长处和短处。组合逻辑控制器设计麻烦,结构复杂,一旦设计完成,就不能再修改或扩充,但它的速度快。微程序控制器设计方便,结构简单,修改或扩充都方便,修改一条机器指令的功能,只需重编所对应的微程序;要增加一条机器指令,只需在控制存储器中增加一段微程序,但是,它是通过执行一段微程。具体对比如下:组合逻辑控制器又称硬布线控制器,由逻辑电路构成,完全靠硬件来实现指令的功能。


Controller combinational logic controller and micro program controller, two kinds of controller each has strengths and weaknesses. Combinational logic controller design problem, the structure is complex, once the design is completed, will not be able to modify or extend again, but its speed is fast. Convenient microprogram controller design, simple structure and is convenient to modify or extend, modify the function of a single machine instruction, only need to reweave the corresponding micro program; To add a machine instruction, need to increase in control storage period of microprogram, however, it is by performing a micro range. Specific contrast is as follows: combinational logic controller is also called the hardwired controller, composed of logic circuit, completely rely on hardware to realize the function instruction.
