[VTA] issue with TLPP design

The hardware guide on VTA says that the dependence tokens (which are used to synchronize between RAW and WAR Queues) are information less. This effectively kills all the task level parallelism because, whenever Producer Q has some items left to be notified, the consumer cannot continue with its task, even if there is no dependency between these tasks. I am sure I am missing something here. Can you please explain the synchronization operation in a little bit more detail. @thierry
