【摘要】 基于TMS32 0VC5 40 7控制的综合驱动器电子组件 (IDE)硬盘的存储器可以用于各种需要大容量数据存储的脱机系统中。文中介绍了TMS32 0VC5 40 7(以下简称C5 40 7)和PDIUSBD1 2 (以下简称D1 2 )的特点及IDE硬盘接口的IDE接口协议 ,它包括IDE接口、IDE寄存器和对硬盘的寻址方式。在此基础上 ,介绍了C5 40 7与IDE硬盘接口及D1 2的连接 ,并且给出了它们之间的连接图。然后介绍了系统的软件的设计 ,其中包括C5 40 7对D1 2的控制、PC机上的应用软件的设计和C5 40 7对硬盘的一个扇区进行读写的软件实现 ,最后给出了对一个扇区进行读写的程序流程。该系统已经实现 ,性能稳定。更多还原

【Abstract】 The embedded hard disk on the TMS320VC5407 can be used in the conditions that require mass storage without PC. In this paper, the characters of TMS320VC5407 and PDIUSBD12 are introduced. The IDE protocol is also introduced in this paper, which including the IDE interface, the registers of IDE and the mode of searching address. Basing on these knowledge, this paper introduces the connections among C5407 and the IDE hard disk and D12, giving the graph of their connections. At last, this paper introduces the software design of this embedded system and gives the figure of the read/write a sector software flow.更多还原
