Claim 3:
4. The method of claim 1, wherein using the information to control the early culling tester comprises:
when the early culling tester is to perform an early culling test that accesses the first culling test data buffer:
determining whether to stall the early culling test based on whether the information indicates that a processing stage of the graphics processing pipeline after the early culling tester is expected to access the same position in the first culling test data buffer; and
when it is determined to stall the early culling test, stalling the early culling test; and
when it is not determined to stall the early culling test, performing the early culling test without stalling; and

when the early culling tester is to perform an early culling test that accesses the second culling test data buffer:
determining whether to stall the early culling test based on whether the information indicates that a processing stage of the graphics processing pipeline after the early culling tester is expected to access the same position in the second culling test data buffer; and
when it is determined to stall the early culling test, stalling the early culling test; and
when it is not determined to stall the early culling test, performing the early culling test without stalling.
