System and method for effectively performing image rotation procedures in a compressed domain

摘要

A system and method for effectively performing image rotation procedures in a compressed domain includes a compression module that performs data compression upon input data blocks to create compressed data blocks that have irregular storage sizes when packed into a display buffer. A rotation module stores compression storage information corresponding to the compressed data blocks into a rotation memory. A decompression module may then access the compression storage information from the rotation memory to locate and read certain of the compressed data blocks in pre-defined image rotation sequences for providing to a display device.
