摘　　要：详细论述了基于NiosⅡ软核处理器的PWM外设模块的整个设计过程,最后构建SOPC系统,并在开发装置上进行了功能验证。文中所述的方法对于开发其它的用户自定义外设具有一定借鉴意义,按照Avalon总线规范将各种自定义外设的驱动程序集成到SOPC Builder的硬件抽象层中,进行设计复用,可以大大提高设计效率和提升数字系统的性能。The designing process of PWM＇ peripheral module had been detailed based on NiosⅡ, build the SOPC system and undertakes a functional verification on it. The design gives some referential help for developing other user-defined peripherals and it could improve the design efficiency and promote the performance function of the digital system by the means of integrating various user-defined peripheral driver in the rule of Avalon bus into the hardware abstract layer of SOPC Builder for design muhiplxing.
