A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes a graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. The graphics pipeline renders and prepares images for display at least in part in response to polygon vertex attribute data and texel color data stored as a texture images in an associated memory. An efficient texturing pipeline arrangement achieves a relatively low chip-footprint by utilizing a single texture coordinate / data processing unit that interleaves the processing of logical direct and indirect texture coordinate data and a texture lookup data feedback path for “recirculating” indirect texture lookup data retrieved from a single texture retrieval unit back to the texture coordinate / data processing unit. Versatile indirect texture referencing is achieved by using the same texture coordinate / data processing unit to transform the recirculated texture lookup data into offsets that may be added to the texture coordinates of a direct texture lookup. A generalized indirect texture API function is provided that supports defining at least four indirect texture referencing operations and allows for selectively associating one of at least eight different texture images with each indirect texture defined. Retrieved indirect texture lookup data is processed as multi-bit binary data triplets of three, four, five, or eight bits. The data triplets are multiplied by a 3×2 texture coordinate offset matrix before being optionally combined with regular non-indirect coordinate data or coordinate data from a previous cycle / stage of processing. Values of the offset matrix elements are variable and may be dynamically defined for each cycle / stage using selected constants. Two additional variable matrix configurations are also defined containing element values obtained from current direct texture coordinates. Circuitry for optionally biasing and scaling retrieved texture data is also provided.

The present invention enables efficient matrix multiplication operations on parallel processing devices. One embodiment is a method for mapping CTAs to result matrix tiles for matrix multiplication operations. Another embodiment is a second method for mapping CTAs to result tiles. Yet other embodiments are methods for mapping the individual threads of a CTA to the elements of a tile for result tile computations, source tile copy operations, and source tile copy and transpose operations. The present invention advantageously enables result matrix elements to be computed on a tile-by-tile basis using multiple CTAs executing concurrently on different streaming multiprocessors, enables source tiles to be copied to local memory to reduce the number accesses from the global memory when computing a result tile, and enables coalesced read operations from the global memory as well as write operations to the local memory without bank conflicts.

A matrix data processor is implemented wherein data elements are stored in physical registers and mapped to logical registers. After being stored in the logical registers, the data elements are then treated as matrix elements. By using a series of variable matrix parameters to define the size and location of the various matrix source and destination elements, as well as the operation(s) to be performed on the matrices, the performance of digital signal processing operations can be significantly enhanced.

Methods and control systems are provided for displaying an image electronically encoded in the form of illumination values using a two-dimensional matrix of image elements, each element adapted to covert energy to emit the light when an illumination value is written thereto. In accordance with one method, an array of elements including less than all of the elements in the matrix are defined to display the image so that the amount of energy consumed by the elements of the matrix when displaying an image using the elements of the array is lower than the amount of energy that the elements of the matrix would consume in displaying the image using all of the elements of the matrix.
