摘　　要：本文详细阐述了便携式DVD与硬盘集成的整体系统方案,并对硬盘选取以及主要芯片类型进行了详细介绍。在简单介绍HDD接口以及主解码驱动相关部分的基本构造的基础上,详细阐述了系统中HDD电源,主解码芯片的DDR选型,SATA硬盘接口,主解码芯片PCI接口转USB接口等如何实现,并且详细描述了系统在Linux系统下如何进行系统及硬盘的调试。充分体现了本系统在H D D与P D V D结合以及实现方面的突出特点。This paper describes the overall system integration scheme of applying hard disk for portable DVD, and introduces the disk type and main chips in details. It is on the basis that simply introduces the HDD interface and the relevant parts of the main decoding driver, and then more introduces the HDD power system, the selection of main decoding chip DDR, SATA hard disk interface, and how to realize the main decoding chip PCI interface converting USB interface. At last it has a brief description of debugging hard disk in the Linux system. It reflects fully the outstanding feature of this system in integrating HDD and PDVD.
