Greg, I have a question. How does a RT-FIFO differ from a regular Queue (found in the Synchronization palate)? It seems to me (after doing some reading about the RT-FIFO here), that the two are essentially the same thing. The only apparent difference is that an RT-FIFO would be specifically for Real-Time applications, while the other queue is for others. Can you please explain the difference between the two and when to use one over the other?
Thanks,
Phil
