Method of and apparatus for encoding and decoding data

摘要

Each block of texture data elements is encoded as a block of texture data that includes: data indicating how to generate a set of data values to be used to generate data values for a set of the texture data elements that the block represents; data indicating a set of integer values to be used to generate the set of data values to be used to generate data values for a set of the texture data elements that the block represents; data indicating a set of index values indicating how to use the generated set of data values to generate data values for texture data elements of the set of texture data elements that the generated set of data values is to be used for; and data indicating the indexing scheme that has been used for the block.

1. A method of encoding a set of texture data elements to be used in a graphics processing system, comprising:
encoding by processing circuitry the set of texture data elements as a block of texture data representing the texture data elements; storing by the processing circuitry in the texture data block:
data indicating how to generate a set of data values used to generate data values for a set of the texture data elements that the block represents,data indicating a set of integer values used to generate the set of data values used to generate data values for a set of the texture data elements that the block represents,data indicating a set of index values indicating how to use the generated set of data values to generate data values for texture data elements of the set of texture data elements that the generated set of data values is used for, anddata indicating the indexing scheme that has been used for the block.
