A method and an apparatus for generating a signature representative of the content of a region of an array of data in a data processing system, where the region of the array of data comprising plural data positions, and each data position having an associated data value or values. A data value or values for a data position of the region of the data array is/are generated. The data value or values for the data position of the region of the data array is/are written to storage that stores the region of the data array as it is being generated. A signature representative of the content of the region of the data array is generated in parallel with the data value or values for the data position of the region of the data array being written to the storage.

A data processing system comprises processing circuitry arranged to generate data to form an output array of data, processing circuitry arranged to store the generated data in an output buffer 15 by writing compressed blocks of data representing particular regions of the output array of data to the output buffer, processing circuitry 14 arranged to read a compressed block of data representing a particular region of the array of data from the output buffer, processing circuitry 16 arranged to acquire meta-data from the compressed block of data, and processing circuitry 21 arranged to process the block of data. The acquired meta-data is used to affect the processing of the block of data.

The present invention facilitates efficient and effective image processing. A network can comprise: a first system configured to perform a first portion of lighting calculations for an image and combing results of the first portion of lighting calculations for the image with results of a second portion of lighting calculations; and a second system configured to perform the second portion of lighting calculations and forward the results of the second portion of the lighting calculations to the first system. The first and second portion of lighting calculations can be associated with indirect lighting calculations and direct lighting calculations respectively. The first system can be a client in a local location and the second system can be a server in a remote location (e.g., a cloud computing environment). The first system and second system can be in a cloud and a video is transmitted to a local system.

A method for rendering content includes initiating a rasterization of a complete version of webpage content, the webpage content including a set of webpage elements, and setting an original tile pixel resolution of the set of webpage elements to be the same as a screen pixel resolution of a display on a content display device. The method includes rasterizing the set of webpage elements at a lower tile resolution onto a tile buffer, the lower tile pixel resolution differing from the original tile pixel resolution by a scaling factor. The method includes scaling up the set of webpage elements rasterized at the lower tile pixel resolution to the screen pixel resolution of the display. Finally, the method includes compositing the rasterized set of webpage elements onto a display during the rasterization of the complete version of the webpage content, and then compositing the complete version of the webpage content.

The device and method described in this application relate generally to graphics processing systems utilizing the tile based rendering technique and more specifically relate to the processing of the framebuffer data in graphics processing applications. The present invention discloses techniques to reduce the bandwidth needed to access the color data stored in the framebuffer. A method for adaptive lossy delta based compression of color data is disclosed. The error rate, that is the amount of color data lost during the lossy compression process, is controlled by various parameters of the rendered tiles produced by the graphics processing system. The compression process is driven by a dedicated unit which enables informed compression decisions with controllable error rate so as the output color data can be reliably decompressed to produce the original color data with minimal or no errors.

A dual scan out display system and method for performing the same are described. In one embodiment, the computing system comprises a display and a controller to provide data for separate portions of the display simultaneously using dual scanout.

A semiconductor device includes; a first memory that stores first and second layer image data portions used to generate first and second frame images on a display device, a second memory that stores a change map, a display controller that generates positional information associated with an image data portion in response to the change map, and an interface that receives image data and positional information and generates a command for updating the image data.

Embodiments of the invention relate to an intelligent title cache system and more particularly to a real-time image motion including an optimized crawl and live video mapping in the intelligent title cache system. Real-time image motion through active 2D transformations on individual pre-rendered image layers enables the real-time flexibility to support features such as smooth, low overhead crawls and live video mapped to graphic surfaces.

An apparatus to facilitate memory tiling is disclosed. The apparatus includes a memory, one or more execution units (EUs) to execute a plurality of processing threads via access to the memory and tiling logic to apply a tiling pattern to memory addresses for data stored in the memory.

A method and system of transmitting a plurality of area-of-interest video codestreams is described. A first video codestream and one or more second video codestreams are generated from a plurality of large format images that are captured. The first video codestream has a first plurality of areas-of-interest selected from the plurality of large format images and the one or more second video codestream have at least a second plurality of areas-of-interest from the same plurality of large format images. The first video codestream is generated at a first frame rate and each of the second video codestreams is generated at a second frame rate. The first and second video codestreams are combined to obtain a combined video codestream. The combined video codestream is then transmitted to a computer system that regenerates the first video codestream and the one or more second video codestreams at their respective frame rates.
