摘要
设计了一种基于ARM Cortex-M4处理器内核的USB2.0主机系统,在ARM处理器上完成了USB2.0主机驱动程序开发,外接USB PHY通过ULPI接口连接ARM的USB控制器,从而将其从USB1.1升级成了USB2.0。该设计方法使USB设备能与ARM进行高速数据通信,可广泛应用于嵌入式系统设计中。
A USB2.0 host system based on ARM Cortex-M4 processor core is designed. To upgrade the USB1.1 to USB2.0, a USB2.0 host driver on the ARM is developed,and the USB PHY is connected to ARM through the ULPI interface. Using this method,USB devices can communicate with ARM in high speed,and this design can be widely used in the embedded system.
