- * B = Y' * Ycoef + Ublue * U'
- *
- * where X' = X * 8 - Xoffset (multiplication is performed to increase
- * precision a bit).
- * Since it operates in YUV420 colorspace, Y component is additionally

- * Input:
- * mm0 - U (4 elems), mm1 - V (4 elems), mm6 - Y (8 elems), mm4 - zero register
- * Output:
