【摘要】 由于Simulink的模块库中,缺少各种可编程接口芯片模块,进行接口电路的仿真主要是通过确定电路的功能之后选择Simulink中的有关模块,对这些模块进行修改,重新封装,构建所需要的电路。结合Intel8255A可编程并行接口芯片(PPI),阐述了利用Simulink实现计算机接口电路仿真的过程。更多还原

【Abstract】 Because there was few programmable interface chip module in the simulink module library, IC (Interface Circuit) simulation was realized by constructing the circuits according to the function requirement and encapsulating them based on modifying the correlative module in Simulink.With the example of Intel 8255A programmable parellel interface (PPI) chip, how to simulate computer interface circuit in simulink was realized and elaborated.更多还原
