That is one one the differences between some applications with real data fr=
om some applications with complex data. My point was that users with DCT ap=
plications should look to DCT specific literature for efficient implementat=
ions rather that to literature on how to pack DCTs into architectures optim=
ized for complex data to avoid the costs of unnecessary packing and unpacki=
ng. and achieve higher efficiency.
