Now the work is accomplished. Any comments or feedback is welcome. I have write several testing programs to test the new FIFO system and the result shows that it works well. I also put attention to the previously reported FIFO bugs and am happy to see that a well known FIFO bug(see PR 76525, 76144, 94772, etc) is eliminated. You can find these testing programs in my perforce branch: //depot/projects/soc2009/fifo/fifo_test/functionality/... More tests will be added next week. -- Regards, Zhao
