用户对仪器的选择，不受设备类型或供应商的限制。 也用于描述一个过程。

1、控制存储器(contmMemory)用来存放各机器指令对应的微程序。译码器用来形成机器指令对应的微程序的入口地址。当将一条机器指令对应的微程序的各条微指令逐条取出，并送到微指令寄存器时，其微操作命令也就按事先的设计发出，因而也就完成了一条机器指令的功能。对每一条机器指令都是如此。

2、微指令的宽度直接决定了微程序控制器的宽度。为了简化控制存储器，可采取一些措施来缩短微指令的宽度。如采用字段译码法分段译码。显然，微指令的控制字段将大大缩短。，一些要同时产生的微操作命令不能安排在同一个字段中。为了进一步缩短控制字段，还可以将字段译码设计成两级或多级。

The user's choice of instrument is not limited by the type of equipment or the supplier. Also used to describe a process.

1, control memory (contmMemory) is used to store the corresponding microprogram of each machine instruction. A decoder is used to form the entry address of a microprogram corresponding to a machine instruction. When each microinstruction of the microprogram corresponding to a machine instruction is taken out one by one and sent to the microinstruction register, the microoperation command is issued according to the prior design, and thus the function of a machine instruction is completed. This is true for every machine instruction.

2, the width of the microinstruction directly determines the width of the microprogram controller. In order to simplify the control memory, some measures can be taken to shorten the width of the microinstructions. If the field decoding method is used for segmentation decoding. Obviously, the control field of the microinstruction will be greatly shortened. Some microoperation commands to be generated at the same time cannot be arranged in the same field. To further shorten the control field, field decoding can also be designed to be two or multiple levels.
