USB 1.1 Device 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

USB 1.1 Compliant Function
Hardware enumeration support
No micro controller/CPU required
FIFO based interface
Written In Verilog
Fully Synthesisable
Tested in Hardware
