Method of determining the state of a tile based deferred rendering processor and apparatus thereof

A tile based deferred rendering processor, comprising:

• a generator operable to generate information indicating the state of the tile based deferred rendering processor when processing a unit of data during a geometry phase and to generate a batch identifier that identifies a batch of data being processed during the geometry phase;
• a store operable to store the batch identifier processed during the geometry phase in association with the state of the tile based deferred rendering processor when processing the batch identifier;
• the generator being further operable to generate information indicating the state of the tile based deferred rendering processor when processing the batch identifier during a rasterisation phase;
• and
• an output device operable to output the stored batch identifier and the stored state information relating to the processing of the unit of data when the state of the tile based deferred rendering processor meets a condition.

A non-transitory computer readable storage medium storing a computer program therein, the computer program, when executed by a processor, causes the processor to perform a method of determining a state of a tile based deferred rendering processor, the method comprising:

• generating information indicating the state of the tile based deferred rendering processor when processing a unit of data during a geometry phase;
• generating a batch identifier that identifies a batch of data being processed during the geometry phase;
• storing the batch identifier processed during the geometry phase in association with the state of the tile based deferred rendering processor when processing the batch identifier;
• generating information indicating the state of the tile based deferred rendering processor when processing the batch identifier during a rasterisation phase;
• and
• outputting the stored batch identifier and the stored state information relating to the processing of the unit of data when the state of the tile based deferred rendering processor meets a condition.
