在很多的电路设计中硬盘仍是解决海量数据存储、降低设计成本的最佳选择之一。为实现硬盘数据的高效可靠读写，文中在对ATA协议及已有硬盘控制器研究的基础上，提出了一种高效的IDE硬盘控制器设计方案。该硬盘控制器实现了ATA协议规定的PIO和UDMA操作，可支持不同速率的寄存器传输和数据传输，支持16位CRC校验，具有灵活、高效的特点。同时，该控制器还具有标准的PLB和DCR总线接口，可直接用于具有CoreConnect总线架构的电路设计，具有很好的可移植性。目前，该控制器已成功应用于某音视频处理芯片中，很好地完成了音视频数据的存储和读写，数据传输稳定可靠，读写速率接近理论最大值。

Hard disk is still a good solution to solve the problem of mass data storage and reducing the design cost in the circuit design. In order to realize the efficient and reliable reading and writing for hard disk data,based on the research of ATA protocol and existing hard disk controller,propose an efficient IDE controller design scheme. The hard disk controller support PIO and UDMA transmission of ATA protocol,which can support register transmission and data transmission with different speed ratio,and 16 bit CRC check,with flexi-ble and efficient feature. At the same time,the controller also has the standard PLB and DCR bus interface,can be directly used for circuit design with CoreConnect bus structure with good portability. At present,the controller has been successfully applied to a video and audio processing chip,completing the data storage and reading and writing of audio and video well,the data transmission is stable and reliable, and the rate is close to the theoretical maximum.
