摘　　要：随着单片机技术越来越广泛的应用,使得串口资源愈显紧缺,为了解决这个问题,本文采用自顶向下的﹑模块化的设计思想,结合单片机的读写操作,设计了一多串口单一中断源的芯片,并采用ModelSim软件对所设计芯片进行逻辑和时序的仿真,本设计在实际应用中具有较高的参考价值。With the wider application of the MCU , there is a greater lack of serial resources. In order to solve the problem, this paper designs a chip that is processed from the top down and divided into many modules. VHDL is used in the design which makes it improved easily. The program is synthesised by ISE using Spartan-H E and emulated by ModelSim, which makes it more feasible and valuable in practice.
