ABSTRACT:
Redundant changes of tracked state issued by an application are filtered out by comparing the new state value with the old value, and if they are the same, no update is made. State changes are collected in on-chip memory and added to the bin if the state vector associated with the bin is out of date. State changes within a bin are done incrementally in temporal order, and a bin is only brought up to date prior to adding in a new primitive if the state has changed since the last primitive was added to it.
