1. A method of data processing, comprising:
receiving at least one bitstream including a plurality of bits, each of the plurality of bits corresponding to a position in the at least one bitstream, and each of the plurality of bits being associated with color data, wherein the plurality of bits includes a set of floating point bits and a set of exponent bits;
arranging an order of the plurality of bits in the at least one bitstream by moving one or more floating point bits of the set of floating point bits and one or more exponent bits of the set of exponent bits in the at least one bitstream, such that at least two of the plurality of bits corresponds to an updated position in the at least one bitstream, wherein the one or more floating point bits are moved to a beginning of the order of the plurality of bits or an end of the order of the plurality of bits;
converting, upon arranging the order of the plurality of bits, the color data associated with each of the plurality of bits in the at least one bitstream; and
compressing, upon converting the color data associated with each of the plurality of bits, the plurality of bits in the at least one bitstream.
