Title: SYSTEM AND METHOD FOR OUT-OF-STREAM ORDER COMPRESSION OF MULTI-MEDIA DATA TILES IN A SYSTEM ON A CHIP
Abstract:
Various embodiments of methods and systems for out-of-stream-order compression of image data tiles in a system on a chip ("SoC") of a portable computing device ("PCD") are disclosed. In an exemplary method an input data transaction comprising an uncompressed data tile is received. A header pixel of at least one sub-tile of the received uncompressed data tile is extracted, where the sub-tile comprises a plurality of data blocks received in an input order. The plurality of data blocks are encoded in the input order, an Tdx code for each of the plurality of encoded data blocks is stored in a stream buffer. The header pixel, a BFLC code for each of the plurality of encoded data blocks, and the Idx code for each of the plurality of encoded data blocks from the stream buffer are packed into an output format.
