嵌入式USB主机系统的研究与设计

Research and Design of Embedded USB Host System

摘要:

介绍了USB主机的核心机制及设计方法。系统创新性的拓展了USB体系的结构，抛开了PC，把USB主机引入到嵌入式系统中，从硬件到软件，完全自主设计。整个系统没有依托任何嵌入式操作系统，因而具有普通意义。

Abstract:

The key technique and the design method of embedded USB host system are discussed.The system extends the structure of USB and brings USB Host into embedded system.The system doesn't depend on any OS.Its hardware,drivers and software of USB host are developed independently.
