摘要
采用TOP-DOWN设计方法,在DE2开发平台上完成音频播放器设计。设计主要包括NiosⅡ软核处理器、音频控制器、I2C控制器和IDE接口等IP核构成的NiosⅡ系统,在此基础上完成μClinux操作系统移植以及完成基于HAL层的音频驱动器的驱动程序开发,最后用C语言在NiosⅡ系统上编写应用程序进行测试。该实现方法即是下一代消费类电子发展的趋势,也是集成电路发展的一个趋势。
Using TOP - DOWN design method to develop audio player in the DE2 platform. The system mainly consists of Nios Ⅱ soft - core processor,audio controller,I^2C controller,IDE interface and other IP core. It completes the μClinux operating system transplantation and driver drives of HAL, using C language write test bench for it. The method is trend of the next generation of consumer electronics and IC.
