1.In this paper, according to the research of the microinstruction design and developing platform of the CISC microprocessor, the microinstruction format is defined, the microprogramming controller is designed and the developing platform of microprogramming is constructed, which includes the microinstruction compiler and emulation model of microprocessor.
论文结合微处理器的设计,对CISC结构微处理器的微程序设计和开发平台进行了深入研究,定义了“龙腾”C1微处理器的微指令格式,完成了微程序控制器的设计,建立了微程序开发平台,包括微处理器的微指令汇编器、微指令仿真模型。
2.The time in which one microinstruction is executed. In general, several microcycles are required to execute one instruction.
执行一个微指令所需的时间，通常执行一条指令需要若干个微周期。
3.Most CISC or VLIW processors are microprogrammed processors,horizontal microinstruction is widely used for its high degree of parallelism,efficiency and flexibility,it is necessary to encode one or several groups of mutually exclusive microoperations in different fields in optimizing the microcode ROM.
大多数CISC处理器和VLIW处理器都采用微程序控制,水平型微指令因其并行能力强、效率高和灵活性强而被广泛使用,为了优化设计微程序控制器,需对水平型微指令中互斥的微操作命令进行字段编码。
