摘要
本文对多媒体芯片Virgine G2嵌入USB主机控制器的软、硬件结构设计做了详细的介绍,给出了VG2与USB接口电路原理图,研发了基于μCOS-Ⅱ的主机控制器芯片的驱动程序。此设计已被合肥工业大学智能研究所应用在汽车数字视音播放系统中,达到了预期的数据传输效果。该方法对USB HOST的设计具有一定的参考价值。
In this paper,VG2 and USB interface circuit is presented .The design of USB host controller about The software and hardware structure is introduced in detail. The driver program of USB host controller based onμCOS-Ⅱis developed. This design is applied to the playing system of the Auto-digital-video-audio. Its effect is good. It can offer the reference to the USB host design to some extent.
