12. The system of claim 10 , further comprising: a bit copy logic coupled to an output of the XOR logic, wherein the bit copy logic is configured to copy any right-most 1 bits of color-specific data portions of the fourth data word to a sixth data word, and a bit mask logic coupled between the XOR logic and the right shifter, wherein the bit mask logic is configured to mask any right-most 1 bits of color-specific data portions of the fourth data word to 0 bits; wherein the right shifter is configured to perform the right shift on the bit masked fourth data word.
12. The system of claim 10 , further comprising: a bit copy logic coupled to an output of the XOR logic, wherein the bit copy logic is configured to copy any right-most 1 bits of color-specific data portions of the fourth data word to a sixth data word, and a bit mask logic coupled between the XOR logic and the right shifter, wherein the bit mask logic is configured to mask any right-most 1 bits of color-specific data portions of the fourth data word to 0 bits; wherein the right shifter is configured to perform the right shift on the bit masked fourth data word. 13. The system of claim 12 , wherein the sixth data word is a fractional portion of average of the first and second data words, further comprising: a second summer; and a third summer; wherein the AND logic, the XOR logic, the bit copy logic, the bit mask logic, the right shifter, and the first summer are configured with regard to an additional pair of received data words to generate a seventh data word that is a non-fractional portion of the average of the additional pair of received data words and to generate a fractional portion of the average of the additional pair of received data words; wherein the AND logic, the XOR logic, the bit copy logic, the bit mask logic, the right shifter, and the first summer are configured with regard to the fifth data word and the seventh data word to generate an eighth data word; wherein the second summer is configured to sum the sixth data word and the fractional portion of the average of the additional pair of received data words; and wherein the third summer is configured to sum the eighth data word and a non-fractional portion of the sum of the sixth data word and the fractional portion of the average of the additional pair of received data words.
