Abstract: Conservative rasterization hardware comprises hardware logic arranged to perform an edge test calculation for each edge of a primitive and for two corners of each pixel in a microtile. The two corners that are used are selected based on the gradient of the edge and the edge test result for one corner is the inner coverage result and the edge test result for the other corner is the outer coverage result for the pixel. An overall outer coverage result for the pixel and the primitive is calculated by combining the outer coverage results for the pixel and each of the edges of the primitive in an AND gate. The overall inner coverage result for the pixel is calculated in a similar manner.

Abstract: Overlay and screen recording techniques are described that enables separate recordings of a screen and one or more overlays that were displayed on the screen during recording. In one example, pixel values of an overlay are blended with pixel values of a screen to paint the overlay onto the screen in a transparent manner that is imperceptible to the human eye but allows for original screen pixel values to be recovered from areas of the screen that were visually occluded by the overlay. This enables a user to display recording controls and visual cues on their screen without having to worry about the overlay visually occluding any screen content during the recording. One or both of the separately recorded screen and overlay streams can then be output for playback to enable viewing of the individual streams without loss in quality or content of the individual streams.

Abstract: A method of managing display data involves maintaining caches (25, 29) of most recently used tiles of display data at a host (21) and at a display control device (22). The caches (25, 29) are synchronised so that they contain the same data in the same locations. When the host (21) generates a tile that needs encoding and transmitting, it checks to see if that tile is already stored in the host cache (25). If so, it sends a cache ID to the display control device (22); otherwise, it encodes and sends the tile. When the display control device (22) receives data, it identifies it either as a cache ID or as an encoded tile. If it is a cache ID, the data is retrieved from the display control device cache (29) and sent for display (23); otherwise, it decodes the tile and sends it for display (23). Both caches (25, 29) are updated so that the tile is indicated as the most recently accessed item in each cache (25, 29).

Abstract: In one embodiment of the present invention a cache unit organizes data stored in an attached memory to optimize accesses to compressed data. In operation, the cache unit introduces a layer of indirection between a physical address associated with a memory access request and groups of blocks in the attached memory. The layer of indirection—virtual tiles—enables the cache unit to selectively store compressed data that would conventionally be stored in separate physical tiles included in a group of blocks in a single physical tile. Because the cache unit stores compressed data associated with multiple physical tiles in a single physical tile and, more specifically, in adjacent locations within the single physical tile, the cache unit coalesces the compressed data into contiguous blocks. Subsequently, upon performing a read operation, the cache unit may retrieve the compressed data conventionally associated with separate physical tiles in a single read operation.
