摘　　要：针对目前国内微处理器实验教学方面的局限性,设计了一种面向教学的16位微处理器。微处理器的运算器运用了一个加法器实现多种操作的方法,占用资源少、执行速度高。同时,采用微程序控制方法可以使处理器的运行过程更加清晰,克服了传统实验不灵活性的缺点,并为实验者留有创新空间。微处理器使用VerilogHDL语言设计实现,支持多种寻址方式,指令系统完善,可实现一般微处理器的功能操作,最后给出了微处理器运行实验结果。To solve the limitations of microprocessor experiments in our coungry,a 16 bit microprocessor is presented.The arithmetic unit is designed by a adder,which cost less resource and run in higher speed,can implement kinds of operations.The design adopting micro-program controlling,which make the working process of the microprocessor clear,conquer the disadvantage of the conventional experiments,the students also can realize the innovating idea in this microprocessor.The microprocessor,which supports kinds of addressing mode and has a complete instruction system,is programmed by verilogHDL and capable of computing operations as a general CPU.The run process is presented in the end.
