摘要： A method and system for implementing programmable texture lookups from texture coordinate sets. The method includes the step of generating a plurality of texture coordinates using a shader module. The shader module executes floating point calculations on received pixel data to generate the texture coordinates. A plurality of texture values are fetched using the texture coordinates. The fetching is performed by a texture unit coupled to receive the texture coordinates from the shader module. The fetching of the texture values is programmable with respect to the texture coordinates such that the number of texture coordinates are decoupled from the number of textures.

摘要： Apparatuses and methods for detecting position conflicts during fragment processing are described. Prior to executing a program on a fragment, a conflict detection unit, within a fragment processor checks if there is a position conflict indicating a RAW (read after write) hazard may exist. A RAW hazard exists when there is a pending write to a destination location that source data will be read from during execution of the program. When the fragment enters a processing pipeline, each destination location that may be written during the processing of the fragment is entered in conflict detection unit. During processing, the conflict detection unit is updated when a pending write to a destination location is completed.

摘要： A programmable graphics system and method for processing high precision graphics data represented in one or more data formats in one or more passes. Graphics program instructions executed by the system control the processing and format conversion of the data. The program instructions and the data are stored in a memory accessible by the system. Within the memory, contiguous memory entries can contain program instructions or data represented in different formats. The format used to represent a particular data element within the data, is specified in the state information maintained in the system and is used to configure format conversion units within the system. High precision data, such as floating color, is processed by the programmable graphics system and output via a digital to analog converter (DAC) for display.

摘要： One embodiment of the present invention sets forth a technique for ensuring cache access instructions are scheduled for execution in a multi-threaded system to improve cache locality and system performance. A credit-based technique may be used to control instruction by instruction scheduling for each warp in a group so that the group of warps is processed uniformly. A credit is computed for each warp and the credit contributes to a weight for each warp. The weight is used to select instructions for the warps that are issued for execution.
