摘　　要：微处理器与协处理器之间的同步问题是微处理器和协处理器协调一致工作的基础 .文中结合机载嵌入式 16位的微处理器NCS2 86 /协处理器NCS2 87系统的设计 ,提出了应用微程序实现微处理器 /协处理器在指令级的同步 .通过布局布线验证了应用微程序实现指令级同步的正确性与有效性 .The synchronization between microprocessor and coprocessor is the base of proper working between them. This paper brings forward the method using micro-programming to realize the synchronization between microprocessor and coprocessor on instruction level, combined with the design of microprocessor NCS286/coprocessor NCS287 system. Finally it is shown that micro-programming is much suitable for instruction level synchronization due to the result of its layout.
