摘　　要：针对目前PALMOS5操作系统还不能支持USB-HOST功能的问题,提出一种基于PALMOS5的USB主机端协议栈的实现方案。该文首先讨论在PDA上开发USB-HOST功能的必要性,并提出解决方案的总体架构。接着针对该总体构架的每一个部分具体分析其实现,并分析方案的可扩展能力,最后通过实现对USB存储设备的支持来验证方案的可行性。Considering the problem of not supporting USB-HOST function on PALM OS5,a project is put forward,which is used to provide a solution of supporting the said function on PALM OS5.This paper first discusses the necessity of enabling the communications between USB devices and PDA.Then,the whole architecture of the project is presented and each part of the architecture is discussed in details.And the project's expandability is also analyzed in the following part of the paper.At last,a sample USB Host Stack which supports USB Mass Storage device is implemented to support the project.
