可编程中断控制器的仿真

Simulink可用作建模、分析和仿真各种动态系统的交互环境,通过Simulink提供的丰富模块资源和工具箱资源,用户很方便建立仿真模型。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Intel 8259A可编程中断控制器(PIC),介绍了利用Simulink对计算机接口电路进行仿真的过程。通过调用Simulink的模块库创建可编程芯片的仿真,删除芯片中多余的引脚,简化了各块芯片的复杂线路,突出了使用Simulink仿真的高效性和准确性。

Simulation of Programmable Interrupt Controller

The Simulink can be used to establish the model,analysis and simulation a variety of interaction environment for dynamic system.Through the abundant module resources and the toolbox resources provided by simulation,user could establish to simulate model expediently.Because there is few programmable interface chip module in the Simulink module library,IC simulation is 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 8259A programmable interrupt controller(PIC),how to simulate computer interface circuit in Simulink is introduced and discussed.Transferring the module store of Simulink creates the simulation of programmable interface chips,by deleting redundant pins and simplifying complicate lines of each chip,it stands out the high efficiency and veracity by using Simulink.
