摘要
在NiosⅡ系统设计中,SoPC Builder开发环境提供许多常用的设备模型,供开发者在系统中添加和调用。而对于其他新设备设计人员可以按照Avalon总线规范将设备驱动程序集成到SoPC Builder的硬件抽象层中,同样可以加载使用,方便了用户开发一个自定制的片上系统。介绍NiosⅡ嵌入式系统内集成Avalon总线的PWM从外设,将PWM应用在嵌入式智能小车监控系统。
In the design of Nios Ⅱ system,SoPC Builder integrates many generic devices mode for developer to use. But for other devices,the driver can be integrated into hardware abstract layer of the SoPC Builder according to Avalon bus norms. It also can be loaded and develops a User - Defined SOC conveniently. The method of designing a User - Defined Avalon device through integrating PWM in the Nios Ⅱ system,and PWM is applied on intelligent vehicle system are introduced.
