摘要
文章讨论了USB外设接口的软硬件实现,其中重点研究了用硬件描述语言在FPGA中实现USB通信协议,同时提供与USB线收发器和MCU的接口,简述了MCU中的Firmware和PC端的客户程序。既可作为单片专用接口电路实现,也可以作为IPCore嵌入到其他SOC应用中。
To realize the USB peripheral device,hardware in FPGA,firmware in MCU a nd client software in PC,it is a system level design which must consider the h ardware and software in a general view.Here special aspect is focused on the US B protocol realized in FPGA which can be designed with HDL.It also provides a i nterface with the line driver and the application with user's software.After v erification,it can be realized as a single chip or as a IP core into other SOC applications.
