+; * Notes:
+; *
+; * This implementation makes use of 16 bit fixed point version of two multiply
+; * constants:
+; *        1.   sqrt(2) * cos (pi/8)
+; *        2.   sqrt(2) * sin (pi/8)
+; * Because the first constant is bigger than 1, to maintain the same 16 bit
+; * fixed point precision as the second one, we use a trick of
+; *        x * a = x + x*(a-1)
+; * so
+; *        x * sqrt(2) * cos (pi/8) = x + x * (sqrt(2) *cos(pi/8)-1).
+; *
+; * For the second constant, because of the 16bit version is 35468, which
+; * is bigger than 32768, in signed 16 bit multiply, it becomes a negative
+; * number.
+; *        (x * (unsigned)35468 >> 16) = x * (signed)35468 >> 16 + x
