USB 1.1 Function IP Core

Description

USB 1.1 slave/device IP core. Default configuration is 6 endpoints:
1 Control, 1 Isochronous IN, 1, Isochronous Out, 1 Bulk IN, 1 Bulk
Out, 1 Interrupt IN. Includes control engine, providing full enumeration
process in hardware - no external micro-controller necessary.
Derived from my USB 2.0 Function IP core, except all the high speed
support logic has been ripped out and the interface was changed from
shared memory to FIFO based.

A basic test bench is now included as well. It should be viewed
as a starting point to write a more comprehensive and complete
test bench.

I expect the users of this core to have some fundamental USB knowledge
and be familiar with the UTMI specification and with the general USB
transceivers (e.g. from philips). If you are not familiar with these two
you should check out www.usb.org and read up on this subject ...

Features

Dependencies

To use this IP core, you must also download the USB 1.1 PHY , Generic FIFOs and the Generic memories models.
