【摘要】 随着DSP技术的发展,美国模拟器件公司(ADI)Blackfin 53x系列微处理器以其优越的性能,在嵌入式系统中得到了越来越广泛的应用,本文完成了基于Blackfin 53x处理器的ATA IDE硬盘的驱动程序的设计。ATA IDE硬盘的总线接口方式与控制时序和ADSP-BF53x的EBIU接口的总线控制时序一致,可将EBIU直接与硬盘的IDE接口相连。文中给出了硬件电路设计方案和对IDE硬盘读写编程的流程图,并详细介绍了软硬件实现中的关键技术。本文所做的工作具有很强的实用性。更多还原

【Abstract】 With the development of DSP technique,the Blackfin 53x processor of Analog Dev-ice,Inc is more and more popular in embedded systems by its outstanding trait..Based on Black-fin 53x,this paper designed the driver of ATA IDE disk.The bus interface mechanism and timing control ofATA IDE disk is consistent with the Blackfln 53x’s EBIU,the IDE interface can be directly connected with EBIU.The paper showed the hadware circuit digram and the flow chart of reading and writing software that IDE works,and the key technologies in the realization were introduced in detail.The job of this paper has a great utiliy value.更多还原
