Hi, friends,
Is it easy to design a USB 2.0 HOST controller with the code base of USB 2.0 DEVICE core in the svn repo? What should I start from? Thanks a lot! Regards, Huang |

Hi,
If you want to design host then just define ur register level architecture first. Like define registers for send request,receive status...etc. after u define your register level architecture in protocol layer u need to make just one controller module inside device IP core. So using ur register level architecture u can call this controller to send tokens or receive token. let me know if u have any problem.. Best Regards: Ravi |

As ravi said first build datapath and then write controller to controll data transfer to deside what is to be sent and when.Same as you do a processor.
