How does the US National Boxing Tournament work?

I need to know the tournament format breakdown for the Amatuer US Nat'l Boxing Tournament (quarterfinals, semifinals, etc.). Also, do all the fights happen in one day? In other words, say I'm a middleweight, do I compete in all the quarterfinals, semifinals, medal fight, etc. all in one day? --I ask this because I know some fighting tournaments like K1 does this format. As well, is this tournament setup the same way as the Olympics (boxing attire, rounds, minutes, scoring, overall format)?
