A METHOD OF DETERMINING THE STATE OF A TILE BASED DEFERRED RENDERING PROCESSOR AND APPARATUS THEREOF

摘要

A method of determining the state of a tile based deferred rendering processor is described. The method comprising the steps of: generating information indicating the state of the tile based deferred rendering processor when processing a unit of data during the geometry phase; generating an identifier that identifies the unit of data being processed during the geometry phase; storing the identifier identifying the unit of data processed during the geometry phase in association with the state of the tile based deferred rendering processor when processing the identified unit of data; generating information indicating the state of the tile based deferred rendering processor when processing the identified unit of data during the rasterisation phase; and outputting the stored 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. An apparatus therefor is also described.
