Abstract: A method for processing video image data including a plurality of different image data types begins by providing tasks to be performed on each different image data type. The image data is divided into a plurality of groups based on the image data type. A set of arithmetic operations required to accomplish the tasks provided for the corresponding image data type is determined. Each arithmetic operation is assigned to one of a plurality of commonly used arithmetic units which performs the arithmetic operation, whereby each image data type is transformed in accordance with the corresponding provided tasks. The transformed image data of each group is combined, completing the processing.

Abstract: Multi-thread video data processing for use in a computer video display system. The parameters of vertex data are grouped into a plurality of groups. The computation needs of each group are broken down into several arithmetic operations to be performed by corresponding arithmetic units. The units concurrently process the vertex data.

Abstract: An apparatus and method allows efficient processing of vertex data received in any suitable format. The method and apparatus accesses stored vertex data that may be stored in a plurality of different formats. A single copy of the received vertex data is stored in memory so that the system does not require a block of memory containing differing formats of the vertex data. The apparatus and method utilizes a universal vertex data fetching mechanism which controls retrieval of vertex data stored in the first format in memory based on multi-format description data. As such, the vertex data that may be received in one of a plurality of formats, is effectively coded so that a data fetcher may appropriately fetch vertex parameter data from suitable addresses independent of the format in which the vertex data was received.
