Abstract:
The present invention provides a USB host controller and control method thereof. The USB host controller comprises a first controller, a second controller and a first memory. The first controller controls first transfer between a host and a USB device. The second controller controls second transfer between the host and the USB device. The first memory is coupled to the first controller and the second controller and is configured to temporarily store data transferred between the host and the USB device. The first controller accesses the first memory during the first transfer, and the second controller accesses the first memory during the second transfer.
