Managing per-tile event count reports in a tile-based architecture

A computing device configured to track per-tile event counts in a tile-based architecture, the computing device comprising:

• a memory;
• and
• a tiling unit coupled to the memory and configured to:
• cause a screen-space pipeline to load a first count value associated with a first cache tile into a count memory,
• cause the screen-space pipeline to process a first set of primitives that intersect the first cache tile,
• cause the screen-space pipeline to store a second count value,
• cause the screen-space pipeline to process a second set of primitives that intersect the first cache tile, and
• cause the screen-space pipeline to store a third count value.

A method for tracking per-tile event counts in a tile-based architecture, the method comprising:

• causing a screen-space pipeline to load a first count value associated with a first cache tile into a count memory,
• causing the screen-space pipeline to process a first set of primitives that intersect the first cache tile,
• causing the screen-space pipeline to store a second count value, and
• wherein at least one primitive in the first set of primitives causes the screen-space pipeline to detect an event type and increment the count memory.
