USB 2.0 Function Core :: Overview
Other project properties
This is a USB 2.0 compliant core. USB 2.0 allows data transfers of 480 Mb/s. Because of the high interface speed, an external PHY will be required with this core. A industry standard PHY interface for USB has been developed. This interface is called USB Transceiver Macrocell Interface or UTMI for short. The host interface of the USB core will be WISHBONE SoC compliant. More information about the USB standard and a full specification can be found at www.usb.org More information about the WISHBONE SoC and a full specification can be found here. The UTMI specification (and various other useful USB papers) can be downloaded from here. For further information, questions and general discussions related to the USB core, please visit the USB Mailing list.
