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 ...
