摘要
USB接口逐渐成为嵌入式系统的标准接口,PPMC是VISO组织提出的带有PCI接口的最小嵌入式系统。文章介绍了一种用于PPMC系统的USB接口的软硬件设计,使得PPMC系统可以类似U盘那样和PC机通讯。该设计采用模块化方法,符合USB1.1标准,稍作修改后,即可以达到USB2.0标准要求。
This paper introduces a design of USB 1.1 interface for the PPMC-based embedded system, which can make the embedded system communicate with the PC in the way U-disk works. All the design is implemented in modeling methodology and can meet the standard of USB1.1. With little improvement the design can meet the standard of USB 2. 0.
