微技术抑遏的基本念念想是将辅导实际所需要的扫数抑遏信号存放在抑遏存储器中，需要时从这个存储器中读取。具体地，它会把操作抑遏信号编成微辅导，并存放在抑遏存储器中。一条机器辅导的功能频繁由好多条微辅导构成的序列来收场，这个微辅导序列被称为微技术。微辅导在抑遏存储器中的存储位置称为微地址。微技术抑遏的基欢喜趣还包括将机器辅导剖析为基本的微呐喊序列，在制造CPU时固化在抑遏存储器CM中。实际一条机器辅导时，CPU表率从CM中取出微辅导产生微呐喊。一条微辅导包含的微呐喊抑遏收场一步（一个节奏）操作，几许条微辅导构成一小段微技术，用来讲明实际一条机器辅导。通过这种神色，微技术抑遏约略收场辅导系统或某些特定抑遏功能，何况具有活泼性、简便性和资本效益等优点。它在当代处罚器抑遏单位的建立、高档话语撑捏、抑遏单位的用户定制、仿真以及革新操作系统等方面皆有环节孝顺。

The basic idea of microprogram control is to store all the control signals required for instruction execution in a control memory, and retrieve them from this memory when needed. Specifically, it encodes the operation control signals into microinstructions and stores them in the control memory. The function of a machine instruction is usually implemented by a sequence of many microinstructions, and this sequence of microinstructions is called a microprogram. The storage location of a microinstruction in the control memory is called a microaddress.

The basic principle of microprogram control also includes decomposing machine instructions into basic microcommand sequences, which are固化 (fixed or embedded) in the control memory (CM) during the manufacturing of the CPU. When executing a machine instruction, the CPU retrieves microinstructions from the CM in sequence to generate microcommands. Each microinstruction contains microcommands that control the implementation of one step (one cycle) of the operation. A series of microinstructions form a small segment of microprogram, which is used to interpret and execute a machine instruction.

Through this approach, microprogram control can implement instruction systems or certain specific control functions, and has the advantages of flexibility, simplicity, and cost-effectiveness. It has made significant contributions in the development of modern processor control units, support for high-level languages, customization of control units开云体育(中国)官方网站, simulation, and the improvement of operating systems.
