GPU compressed texture processing method

The invention discloses a GPU compressed texture processing method. The method specifically comprises the following steps: further coding GPU compressed texture resources; employing a similar vector quantization method for processing a data block; recalculating the pixel palette index by controlling the mean square error; employing a differential coding thought as reference, removing spatial redundancy, generating a pixel palette index dictionary, performing YCoCg transformation and discrete wavelet compression on pixels in all the data blocks, further removing the data redundancy, and finallyprocessing and interweaving data streams based on a finite state entropy coding method of an asymmetric digital system to generate efficient compressed texture resources. The invention has the beneficial effects that the storage size of compressed texture resources is reduced; the data redundancy is reduced, and the decoding performance and the loading efficiency are improved; the occupation of avideo memory is reduced,
