9468/33-08-10 控制器分組合邏輯控制器和微程序控制器,兩種控制器各有長處和短處。
組合邏輯控制器設計麻煩,結構復雜,一旦設計完成,就不能再修改或擴充,但它的速度快。
9468/33-08-10 微程序控制器設計方便,結構簡單,修改或擴充都方便,修改一條機器指令的功能,只需重編所對應的微程序;要增加一條機器指令,只需在控制存儲器中增加一段微程序,但是,它是通過執行一段微程。
9468/33-08-10 具體對比如下:組合邏輯控制器又稱硬布線控制器,由邏輯電路構成,完全靠硬件來實現指令的功能。
9468/33-08-10 Controllers are divided into combinational logic controllers and microprogrammed controllers. Both controllers have their own strengths and weaknesses.
9468/33-08-10 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.
9468/33-08-10 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.
9468/33-08-10 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.
