P243211B2M0C88K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。
P243211B2M0C88K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。
P243211B2M0C88K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。
P243211B2M0C88K Controllers are divided into combinational logic controllers and microprogrammed controllers. Both controllers have their own strengths and weaknesses. The combinational logic controller is troublesome to design and has a complex structure. Once the design is completed, it cannot be modified or expanded, but it is fast.
P243211B2M0C88K Microprogrammed controllers are easy to design, simple in structure, and easy to modify or expand. To modify the function of a machine instruction, you only need to reprogram the corresponding microprogram; to add a machine instruction, you only need to add a microprogram in the control memory. However, it does so by executing a mini-routine.
P243211B2M0C88K The specific comparison is as follows: Combinational logic controllers, also known as hard-wired controllers, are composed of logic circuits and rely entirely on hardware to implement instruction functions.
